Who hasn’t dreamt of being at the summit by sunrise? Just 100 more meters to go. How do we picture the moment of arrival? First, stretch out on the alpine meadow, soak in the view. And then? Coffee! But not just any coffee—one that truly lives up to its name and makes us happy. Back home, we’ve got our fancy espresso machine, so we’re definitely not Team Nescafé. Even up here, we want the finest coffee experience and that cozy hygge moment. Because great taste knows no limits.

At the same time, space on our bikes or in our hiking backpacks is limited, and we don’t want to lug around too much gear. So, what does it take to brew the perfect summit coffee? The best portable coffee maker? The finest beans? Or maybe the perfect grinder? We’ll show you what we packed for bikepacking in the Dolomites.

You can find the full test at our sister magazine DOWNTOWN.

After a rainy trail session, you often ask yourself: when and how should you clean your bike? Ideally, before the mud gets a chance to turn into a stubborn dry crust on the frame. This is precisely where the Muc-Off mobile pressure washer comes into play: equipped with a 40V lithium-ion battery, a 500-watt motor, and a 20-liter water tank, this pressure washer promises a quick and thorough clean – either in the car park after a ride or outside your house if if you don’t have a garden with a hose pipe.

The pressure washer comes standard with four nozzles, each designed for different applications. A standout feature is the “Snow Foamer,” which, in combination with Muc-Off’s bike cleaner, produces a thick snow-like foam – whether you need this is up to you. Additionally, there is a nozzle specifically for bicycles (gentle), one for motorcycles (powerful), and an adjustable nozzle for particularly stubborn dirt (intense).

Assembling and disassembling the Muc-Off mobile pressure washer

The mobile pressure washer is designed to be intuitive and straightforward to use: simply insert the battery, fill the tank from the top, connect the hose to a nozzle and the unit using the click mechanism, and press the power button – one of the two buttons on the device. Switching to another nozzle can be a bit tricky at first but becomes easier with practice.

Switching from Eco to Boost mode is done via the second button on the back of the device. When dismantling, the connections between the hose and the nozzle or device need to be disengaged using a sliding mechanism. This works smoothly, though a bit of residual water might remain in the system; tilting the device briefly helps to drain it completely.

The Muc-Off mobile pressure washer in practice

For an extensive test, we took the Muc-Off Mobile Pressure Washer along on a major shoot in cold, wet weather. Initially, we tried to increase battery life by using the Eco mode but soon opted for more power. The Boost mode, in contrast, was quite impressive – a single charge in this mode is enough to clean up to seven muddy bikes.

A similar experience applied to the choice of nozzle: while the bike nozzle is certainly gentle on bearings and sensitive eMTB electronics, it’s also gentle on the dirt. The motorcycle nozzle, on the other hand, takes on the job with satisfying vigor. The combination of the motorcycle nozzle and Boost mode is particularly enjoyable– though you’ll have to be careful in sensitive areas of the bike.

The 20-liter water tank is sufficient for cleaning two very dirty bikes, making it practical for use in a parking lot after a ride or in front of a city apartment without access to a garden hose. Naturally, the main limitation of the mobile pressure washer is water supply: Muc-Off offers an additional water tank for transport in a car, as the pressure washer itself isn’t suitable for that purpose. At home, the tank can be filled from a tap or in the bathtub, although this means that you’ll have to carry the unit to the place where you’re washing the bike – on flat, smoother surfaces you can roll it on the sturdy wheels by pulling the handle.

Conclusions about the Muc-Off mobile pressure washer

While not every accessory managed to impress us, the Muc-Off mobile pressure washer performs its core task brilliantly. For a battery-powered pressure washer, the cleaning power is remarkable, especially with the right nozzle and in Boost mode. Both the battery life and the available water volume are suitable for the intended scenarios mentioned above. So, if you’re in the market for a battery-powered pressure washer for your bike, the Muc-Off’s mobile pressure washer is definitely worth considering.

• Mobile concept
• Easy assembly and disassembly
• Excellent cleaning performance
• Good battery life and water capacity

Crazy. We vividly remember that moment in July 2024, when the house of cards suddenly collapsed, and years of rock-solid conviction began to crumble. It was late at night, we were sitting in the lobby of the Gekko House hotel in Frankfurt. Once again, several new e-bike motors had been presented at Eurobike 2024, and we were the only magazine to be granted the opportunity to test a newcomer in the Taunus mountain range. Exclusively. Peter and Mike walked into the hotel lobby, covered in mud and still in their riding gear, sharing their first impressions. And one thing was immediately clear: some of the competitors are in for a serious wake-up call!

“The best e-bike motor for eMTBs doesn’t exist…”

2017 was the last year we crowned a winner in our motor comparison test. After that, it simply wasn’t feasible anymore. Our reason at the time: “There’s no longer a single best e-mountain bike motor; the market has diversified too much, and with the vast range of customization options, isolated evaluation of individual models makes little sense. Ultimately, the best motor is only as good as the bike it powers. If the bike’s core design is flawed, even the best motor won’t make it a great e-mountain bike.”

This still holds true today.

But what if…

…there were an ultimate eMTB motor? An e-bike motor capable of uniting seemingly contradictory qualities to outperform all other motors currently available on the market in many ways? A significantly more powerful motor that is also easier to control than any competitor? A motor with a much higher power-to-weight ratio? More app features combined with outstanding usability? And an integration that would make even the current market leaders look outdated? The ultimate question: does such a motor exist? Or just on the paper?”

Spoiler: Not only does the best e-bike motor of 2025 exist, but…

Forget the whole “opposites attract” yada yada – opposites can be united! The first representatives of a new generation of e-bike motors manage to combine all the qualities mentioned above. However, there are still open questions and uncertainties that only the 2025 season will answer. The fact is, not only have these new motor systems emerged, but are also leading to significantly better bikes that are easier to ride and more capable!

However, where there are winners, there are also losers: a bioproduct of this development is that light-support eMTBs are losing their relevance. Our 2024 light E-MTB comparison test with nine exciting bikes already showed that the era of light-support motors is coming to an end, and the choice between light-support and full-power is, in many respects, already becoming obsolete. At the same time, the overall design of the bike, together with the battery concept, is gaining increasing importance.

​​The good news: 2025 is set to be an outstanding year for e-mountain bikers, and from a technology standpoint alone, it’s well worth investing in a next-generation eMTB! Here’s a little teaser: for 2025, we have a clear winner in our well-known, extensive motor comparison test. And a best-buy recommendation too! Just keep reading to find out more! But remember: every motor is only as good as the bike its part of. And for the math-enthusiasts amongst us, we even have an equation:

Shit bike + awesome motor = Shit bike

2025 as the year of reckoning: a survival and positioning battle for motor manufacturers

Who’s got the stamina to succeed? For many motor manufacturers, 2025 is all or nothing! This model year brings more motor manufacturers than ever, numerous updates, and some incredibly exciting newcomers– which makes for an exceptionally fierce competition.

In fact, there are currently more motor manufacturers than bike brands can absorb. Development costs are still high, and on top of that, bike brands are currently acting prudently. Not because the bike market is performing poorly per se, but because projections are not being met, and some large manufacturers’ inventories remained overstocked from recent years. The critical question is: who’s betting on the right technology and can deliver a cohesive package that goes far beyond delivering maximum performance or successful integration and connectivity? Ultimately, it’s the details – and, of course, price points – that lead some bike brands to forgo even high-quality motors or regret their choices. Many motor manufacturers stumble because they produce motors with excellent performance but lack a globally functioning service network. In the end, it takes a strong overall package, not just a good motor.

This raises an exciting question: which motor brands will bike manufacturers actually choose to integrate and feature on their bikes over the coming years? Without a doubt, the pressure on motor manufacturers is massive – and that’s a good thing, especially for end users. Competition drives the market and, in the mid to long term, fosters innovation.

Always up to date: Our extensive e-bike motor comparison test

Our comprehensive motor comparison test includes all relevant systems currently available on the market, and is constantly updated to include the latest motor systems. The goal of this e-bike motor comparison is to provide you with the ultimate market overview, detailing the features, capabilities, strengths, and weaknesses of each system to fully support you in choosing your (next) eMTB. In addition to previously tested systems from Bosch, Brose, FAZUA, GIANT, Panasonic, Pinion, Shimano, Specialized, TQ, and Yamaha, we’re now adding the exciting new DJI Avinox and the Bosch Performance Line CX Gen5 motor. We were also the only magazine to test the ZF Bike Eco System in the new R RAYMON Tarok eMTB, though not yet in the lab or in direct comparison with its competitors – but don’t worry, we’ll catch up on that as soon as the motor is available!

Our test field – These are the e-bike motors we’ve tested

All ebike motors in the lab and on the trail: real-world insights beyond theory!

For our e-bike motor comparison test, we completed countless test runs with all motor systems, covering thousands of vertical metres, both up and downhill. We used the same test track for all motors to ensure consistent benchmarking, and used the same motors on different bikes and all types of terrain. But why on different bikes? Not every motor performs the same on every bike– the strengths and weaknesses of a drive also depend on the bike’s characteristics and overall concept. No other magazine tests such a large selection of current eMTBs as intensively or for as long as we do. As a result, we’ve built up extensive experience with numerous motor systems over months and years.

We also took over the lab at the renowned Velotec testing institute to put all motors through the wringer paces on the test bench. However, if you’re expecting large-scale graphs, we’ll have to disappoint you – or rather, educate you like a teacher: isolated data and impressive charts might look great might be very popular amongst some of our readers, but they rarely reflect the complex reality of an eMTB on the trail. Such charts often lead to premature and incorrect conclusions and should therefore ALWAYS be approached with caution.

There’s one clear reason for this: unlike a car, an eMTB is a human/machine hybrid. And since no two riders are alike, there are countless individual factors that influence how a motor performs and feels in real live scenarios. Even with cars, acceleration and horsepower figures alone say very little about how a vehicle handles on a racetrack, how well it corners, or how it performs under varying road conditions. That’s why we’ve carefully integrated the lab-test results into each test report, as they help support our practical insights and can add extra context. But generally speaking, what you don’t feel or perceive on the trail is just theory!

Top 7 – What Makes a good eMTB motor?

A high-quality motor system is made up of numerous critical factors that have a significant impact on the riding experience. But which features are especially important for getting the most out of your eMTB? Here are the top 7!

1. Power specs impress, but riding enjoyment rules.

Let’s start with the motor itself: raw performance data such as torque and peak power have the same allure as a car engine’s horsepower. Yet they should never take top priority. Whether you’re a beginner or a seasoned trail veteran, and whether you prioritise safety or speed, response behaviour, modulation, and power delivery are at least as important as power output and torque. Unfortunately, these qualities can’t be quantified in simple numbers. Optimal cadence range may serve as an indicator, but ultimately, many different factors come into play.

Here’s the background: some motors only reach full power at high pedalling cadences or respond poorly to pedalling asymmetries, meaning that certain riding styles may not allow you to draw the motor’s full power. Other motors, however, adapt better to some riding habits and enable less frequent and precise shifting, as their power is sufficient to handle even suboptimal cadences.

2. Your motor’s soundtrack: loud or quiet?

Another key factor is the noise and volume of the motor under load. Some drives get relatively loud at certain RPMs and load ranges, while others remain relatively quiet. Then there’s mechanical rattling, which is especially an issue with the Shimano EP801, the older Bosch CX Gen4, and the Bosch CX Race.

3. Batteries à la Carte: Modular battery concepts for every need

Every motor needs power– in other words, a battery. A practical selection of battery options with high energy density and frame-integrated designs is essential. A lightweight, well-integrated motor system offers clear advantages for bike brands, not only to achieve a low centre of gravity and improved handling, but also to create aesthetically pleasing bike designs. Sleek, seamless units or bulky, rectangular protrusions on the downtube or bottom bracket? We definitely have a preference…

Many manufacturers now offer modular battery concepts, which allow you to adjust battery capacity to your needs without carrying the extra weight of oversized batteries. Range extenders are a great option to expand the integrated battery. Furthermore, some bike brands design their models so customers can select the base battery size as well. One of them is Basque manufacturer Orbea, which secured the coveted ‘Best eMTB of 2024’ title in our extensive eMTB comparison test with the Orbea Wild, as well as the ‘Best Light eMTB of 2024’ with the Orbea Rise LT.

Using Orbea’s online configurator, both the Wild with its Bosch motor, and the Rise with its Shimano drive, can be configured with two different battery sizes and the additional range extender, which can be carried inside the bottle cage. Other brands like Merida, Moustache, FOCUS, Canyon, and newcomer Amflow give you different battery size options too –which we highly welcome. After all, having different options for the main battery is crucial for a bike tailored to individual needs, and an additional range extender ensures you’re prepared for any adventure!

4. Full Control: Smart Features or Frustrating Operation?

The motor’s ‘ecosystem’ determines whether handling is a pleasure or a pain. User-friendly remotes paired with an informative, clear, and easy-to-read display bring joy, while bulky, poorly placed remotes with oversized displays that add no value can be extremely. Intuitive apps make it simple to customise the motor’s characteristics, provide additional ride data and information, or even alert users about system errors. Extra features like smart navigation and integrated theft protection (with alarm and GPS) open up new possibilities for both daily use and adventures, giving you peace of mind when leaving your beloved bike unattended at a mountain hut for a quick break.

User needs vary greatly too: some want high information density and full functionality on their display, while others prefer a minimalist setup.

5. Additional hardware features of e-bike motors

Apart from integrating software features, some manufacturers go one step further and integrate other bike components like the drivetrain and brakes. Shimano and Bosch have their own ABS systems, which improve safety especially on loose surfaces. Bosch take it one step further and offer two different systems: the Bosch ABS is for moderate tours, while the ABS Pro is designed for trail riding – and delivers an impressive performance. Drivetrain specialists Shimano and SRAM not only have their own motor system, but are also integrating their drivetrains with an automatic function and other features into their ecosystem. We have already tested both systems in a direct comparison to tell you what the differences are and which eMTB rider types can benefit from an automatic drivetrain. Bosch, too, followed suit in summer 2024, developing the automatic Bosch eShift system in close collaboration with TRP. Pinion integrate the autoshift feature directly into their motor-gearbox unit, but other manufacturers also offer exciting e-bike motors with integrated gear shifting, which we have already tested in direct comparison.

6. When things go wrong: Spare parts and service for your e-bike motor

Beyond handling and usability, the technical design and redundancy of certain components are crucial too: can the bike still be powered on and used if, for example, the remote is damaged in a crash? The same goes for both external and internal battery charging. After-sales support and ease of maintenance play a vital role here, as spare parts and reliable local service are essential. Many of us keep our bikes for years, making these indispensable factors. Depending on where you live and ride, certain brands may not be viable options due to a lack of service. Some smart bike manufacturers even choose not to offer certain models in regions where service quality is poor, avoiding frustration for customers.

When buying, it’s critical to consider system reliability and the service network, especially if you’re outside the main e-bike markets like Central Europe. While service is often excellent there, it can be abysmal for some brands in more remote regions. In our e-bike motor comparison test, Bosch, Shimano, Specialized, and GIANT currently lead in service availability.

All these factors combined give each motor system in our comparison its own unique character. Price is also an important criterion, although a rather hard one to view in isolation since you’re purchasing a complete bike, not just the motor. Still, there are substantial differences in this regard too.

7. Pickier than Tinder: Find your perfect motor System match

Balancing act or specialty? Ultimately, the right motor system depends on the needs of each rider–you just need to find your match. While some e-bike motors cater to niche uses, focusing on low weight and ultra-sleek integration to the point where it’s nearly indistinguishable from a traditional bike, others are all-rounders that appeal to a wide range of riders.

But beware! We can’t stress this enough: don’t just buy a bike with closed eyes because of the motor system. The motor is only one cog in a larger machine, which only works as a cohesive package in conjunction with other components. Understanding these relationships is key to appreciating the bikes. That’s also good advice for Tinder

Shit bike + awesome motor = Shit bike: A Brief exposition

Before diving into the motors, we need to take a quick detour to discuss the latest generation of eMTBs and motor concepts. In summer 2024, we conducted our large light e-MTB comparison test with 9 current models. The shocking realisation? The era of light eMTBs is coming to an end.

With the latest generation of motor systems and battery concepts, categorization is no longer necessary: Light eMTBs may have been in the spotlight for the past few years, and were considered the pinnacle of innovation, but now they’re on the verge of extinction. Full-power motor systems are becoming increasingly smaller, more powerful, and lighter, rendering traditional ‘light support’ systems on eMTBs irrelevant in the long run. And it makes sense: why ride with a weaker motor and smaller battery when there are bikes with more power and greater battery capacity at nearly the same weight?

As mentioned above, the battery concept is becoming ever more crucial, even determining whether a bike qualifies as a light eMTB. Our 2024 light eMTB comparison test made this abundantly clear, with many lightweight eMTBs featuring full-power motors excelling in the rankings! Since our latest comparison test, several more motors have been introduced that push the boundaries even further.

How much battery capacity and motor power do I need?

Over recent years, battery capacity has been one of the hottest topics in the eMTB world. After engaging in a fierce battery arms race, most manufacturers have now settled on a balanced approach and offer a wide range of options to customers. What’s exciting: there’s a lot happening with batteries, and the differences are growing!

Earlier, we discussed modular battery concepts, integration, and energy density– and we’ll continue exploring these themes in this chapter! Let’s start with four common battery myths:

1. The bigger the battery, the bigger the range?

Trick question: Which battery capacity will take you farther – 320 Wh or 700 Wh? The only correct response is another question: with what motor is it paired? Isolated numbers tempt us to draw premature conclusions. There are many reasons why comparing battery sizes across different motor systems doesn’t make sense.

While battery capacity is an important reference point, range can only be accurately assessed in conjunction with the motor and its output. There are significant differences in both motor efficiency and power output.

If you ride a Bosch SX motor with a 400 Wh battery at a relaxed pace, you can actually achieve impressive range. But if you push it, drawing out its 600 W peak power over an extended period of time, you’ll quickly see the range estimates on your display plummet. This makes sense: it has the same peak power as its larger Bosch sibling, the CX. The maths is straightforward: higher energy consumption per hour (in watts) reduces the ride time before the 400 Wh battery runs out.

It’s the same story with a Specialized SL 1.2 motor and 320 Wh battery, though its maximum output is 240 W, which means that, mathematically, it can’t consume more than 240 Wh per hour at full power. This gives you, theoretically, about 1 hour and 20 minutes of ride time at maximum output before the battery depletes.

In real-world conditions, actual range depends on numerous factors such as efficiency, support level, rider weight, terrain, topography, cadence, pedalling style, bike components, and more. Additionally, many motor manufacturers don’t specify battery capacity precisely– either for marketing reasons or because incremental improvements in cell design and chemistry can increase actual capacity even within a model year.

2. The bigger the battery, the heavier the bike?

Really? While this rule of thumb held true for years, there are now significant differences in energy density– the battery capacity divided by battery weight (Wh/kg). This is due to several factors: the type of cells used and their chemistry, as well as the design, casing, and all safety-related technology. Another factor is how well the battery integrates into the bike, and the additional hardware required, like the mounts and brackets. After all, where’s the point in having a lightweight battery if the integration adds substantial weight to the frame? That’s why providing a table of different battery weights wouldn’t make much sense!

3. Power, weight, range– Pick two!

Not only does the size of the battery affect range but also plays a crucial role in the bike’s handling. This is why some bike manufacturers combine a full-power motor with a smaller battery, sometimes limiting the motor’s power via software slightly. This setup combines the punch of a powerful motor with a lighter overall package and the associated benefits. Good examples include the Orbea Rise LT, the Cannondale Moterra SL with the Shimano EP801, and the GIANT SyncDrive Pro2. If you enjoy short, punchy climbs and value more natural handling on descents, these could be great options.

As you can see, a strict categorization isn’t possible and always depends on the bike manufacturer’s implementation. Motors like the FAZUA Ride 60 and Bosch SX are designed as hybrid drives that want to strike the balance between weight and power. The Bosch Performance Line SX motor, for example, falls squarely in the ‘minimal-assist’ weight class while delivering peak performance closer to full-power motors. For sporty riding, it can even hold its own against many full-power motors.

If you’re after a light footed feel and opt for a light-support motor like the TQ HPR50, make sure it’s installed in a lightweight bike. Depending on how extreme you plan to go off-road, durability and component ruggedness are essential. Conversely, the bike’s nimble handling will be compromised if you add the heaviest motor system with a large, heavy battery. Avoid limiting yourself to two simple categories, and, instead, explore the diversity among systems and find the combination that best suits you.

Do you want powerful torque for the steepest technical climbs or gentler power for relaxed rides? A big battery for long tours or a smaller one for short trips and more natural handling? Full control and extensive riding data on the handlebar display, or a minimalist display-remote solution with a clean look? How much do you value the adjustability options of a motor system? Do you want to be able to fine-tune its behaviour to suit your needs, or are you happy with just hopping on and riding? Only you can answer these questions for yourself. With our e-bike motor comparison test, we aim to help you find the right product for your requirements and avoid costly mistakes or frustration.

4. Bonus: Power, weight, range– Choose all three!

The new DJI Avinox motor is the first of a new generation of motors where you no longer have to choose between maximum power, low weight, and long range. In the AMFLOW PL Carbon – the only bike currently available with the Avinox motor– you can already see where this journey is headed! Which brings us directly to the crucial question:

What’s the best e-bike motor of 2025?

The best shoe is worthless if it doesn’t fit comfortably. And it’s the same story with e-bike motors, with one key difference: not only must a motor suit your riding style and personal needs, but also match the character and overall design of the bike.

Highlights and lowlights of the e-bike motors from Our 2025 Comparison Test

Below, we provide an overview of the standout highlights and lowlights from our motor test field. This overview doesn’t aim to be exhaustive but rather to focus on specific features and qualities that either impressed or disappointed us, giving you a snapshot of what the current market offers.

The ultimate overview – e-bike motor comparison test

To provide you with a comprehensive overview of all relevant e-bike motors and essential insights for your next bike purchase, we’ll now break down each motor we tested, highlighting unique features, strengths, and weaknesses.

The crown jewel of this chapter: for the first time in seven years, we’re awarding both a Best in Test and BestBuy recommendation. Why now? Because we’re at the dawn of a new generation of e-bike motors, which combine the best of light-support and full-power systems or presenting complete, well-rounded motor setups that simplify the final buying decision– or at least point you in the right direction. Ultimately, remember that any motor is only as good as the bike it’s part of.

We’ve already explained that modern e-bike motors can be both lightweight and powerful. A bike’s character depends not only on the motor but also on the battery concept and the overall bike design – including geometry, kinematics, and components. While the best e-bike motors enable versatile bike concepts, some motors are better suited to specific uses. Below, we group similar motor concepts to provide a market overview and highlight the subtle differences. For a deep dive into each motor, click on the respective links.

Während die besten E-Bike Motoren sehr variable Bike-Konzepte zulassen, sind auch manche Motoren für eher spezielle Einsatzzwecke geeignet. Im Folgenden bündeln wir ähnliche Motorkonzepte, um euch eine Einordnung in den Markt zu geben und die feinen Unterschiede abzubilden. Um noch tiefer in jeden Motor einzutauchen, klickt einfach auf die jeweiligen Links.

The Specialized SL1.2 and TQ HPR50 set the standard for a natural ride feel on e-mountainbikes. Both motors deliver subtle support, even at maximum assistance, and are geared toward a sporty riding style, offering power comparable to the ECO mode of full-power motors. Both require higher pedalling cadence and the right gear choice.

With 60 Nm of torque and 350 W peak power, the FAZUA Ride 60 is amongst the more powerful light-support motors in our test. However, reliability is a major concern, as even with the right technical setup, performance is impacted by system failures. Despite promising specifications and multiple software updates, technical issues with the FAZUA Ride 60 have kept us from giving it a wholehearted recommendation. Similar issues are reported by users in forums like Pinkbike, though few publications are willing to address them openly. FAZUA’s new parent company, Porsche eBike Performance GmbH, is likely devoting most resources to developing its upcoming 2026 Porsche motor, meaning only limited improvements are expected.

The Bosch Performance Line SX feels even more powerful than the FAZUA Ride 60 and offers 600 W of peak power, leaning towards the full-power category. Despite its impressive performance, it is bulkier and not as easy to integrate into the frame as some other light-support drives. Thanks to the extensive configurability and Bosch’s reliable global support network, the Performance Line SX is a very good choice.

The Bosch Performance Line CX is a true classic. The 5th generation, released in fall 2024, is slightly lighter and smaller than its predecessor and includes an improved drivetrain to eliminate mechanical rattling. While delivering the same 85 Nm of torque and 600 W peak power as its predecessor, the CX (Gen5) brings enhancements in sensor technology and responsiveness, while at the same time ensuring a quieter ride.

While the Shimano EP801 doesn’t quite match the Bosch Performance Line CX in terms of sheer power, it excels with easy handling, proving an excellent choice for both beginners and advanced riders. Unlike Bosch, Shimano allow third-party batteries, creating more options for customised battery setups and frame designs. Additionally, the EP801 is available with a race-focused software similar to Bosch’s CX Race. We’re excited to see how it performs on the trail! Alongside the widely popular Shimano EP801 drive, the Japanese manufacturer also OFFERS the MORE COMPACT Shimano EP6 drive. This is almost identical in construction and delivers the same torque as the EP801, but relies on a cheaper and slightly heavier aluminium housing.

The GIANT SyncDrive Pro2, which is based on the Yamaha PW-X3, improves on its original platform with a smoother power delivery. Although the remote and display still lack information density, they are well integrated into the bike.

Until late 2024, the Panasonic GX Ultimate was the most powerful drive in our comparison test, churning out 95 Nm of torque. However, with its abrupt power delivery, it’s challenging to control, thus requiring an experienced rider to control it.

Brose Drive S Mag offers bike manufacturers unparalleled flexibility in motor integration and characteristics. While the overall quality depends heavily on the bike manufacturer’s implementation, the Drive S Mag delivers strong performance, and the model we tested provided a natural ride feel despite its high power.

The Specialized 2.2 motor, which is based on the Brose Drive S Mag, offers powerful torque with controlled power delivery, ranking high in terms of app features and connectivity within our test field.

The Pinion MGU E1.12 combines a responsive motor with Pinion’s internal gear hub. This motor-gearbox unit has the potential to revolutionise the e-bike market, though its somewhat clunky shifting performance currently limits its use primarily to touring bikes, where its low maintenance and smart shifting features shine. For trail-focused eMTBs, it’s less common.

Best Buy: Bosch Performance Line CX (Gen5)

The Bosch Performance Line CX motor has only gotten better with the 5th generation. Thanks to enhanced sensors, refined responsiveness, and a decoupled drivetrain, the Bosch CX (Gen5) is now lighter, slightly smaller, and, finally, quieter! The familiar metallic clunking noise is gone, allowing trail riders to enjoy a quiet descent. With the best global service network and proven technology, the Bosch CX is a rock-solid choice when shopping for a new eMTB, offering outstanding performance, a strong ecosystem, and a variety of battery and range extender options. This system is foolproof– provided you choose a bike that meets your needs!

Best in Test: DJI Avinox e-bike motor

No motor has caused as much buzz this year as the new DJI Avinox. After our initial test in the Taunus mountain range – you may remember that pivotal moment in the Frankfurt hotel lobby – it was clear: this motor plays in a league of its own, not only in terms of specs but also as far as ride performance, connectivity, and usability go. The DJI Avinox system impresses with a user-friendly app packed with features that overshadow the competition.

DJI’s debut is the first of a new generation of e-bike motors that simplify the eMTB market, reduce model lines, and take e-mountainbiking to the next level. Why? Because you no longer have to choose between light or full-power eMTB. In terms of energy density, power, and power-to-weight ratio, the DJI Avinox system outshines every other system currently available on the market– and does so at a very competitive price thanks to Amflow’s direct-to-consumer sales model.

However, as with any new player, there are some questions to be asked: currently, the Avinox system is only available on one bike, and we’re waiting to see when other brands will adopt it. Will a range extender be available in the future? And what about long-term durability and service quality, which are both major challenges for bike manufacturers? Only the future will answer these questions. Additionally, there are regulatory issues regarding operating licences in the U.S., where pending legislation aims to ban DJI drones – a factor preventing some American brands from collaborating with DJI.

These are typical challenges for a new system. The fact remains, though, that DJI’s reputation as a tech and direct-to-consumer brand is well deserved, as evidenced by this impressive debut – an instant game-changer that hints at where the e-bike market is heading. Thus, a well-deserved test victory! Congratulations! 恭喜 DJI!

Next question: what’s the best eMTB of 2025?

Once again, where there are winners, there are losers too. The 2025 model lineup not only offers more power, better customizability and usability, but also allows for better bike designs. From a technical point of view, 2025 is a good year to upgrade to a new eMTB. And even better: new motor systems like the DJI Avinox test winner and Bosch CX Gen5 Best Buy bring an undeniable increase in riding enjoyment!

You already know the equation: a poor bike + great motor = poor bike. That’s why we’re eagerly anticipating our upcoming eMTB comparison test, where we’ll be inviting over 30 of the hottest eMTBsof 2025. After all, the question of the best eMTB motor is always tied to the next question: what’s the best eMTB? We’re on it!

Glossary – The most important eMTB motor terminology and key figures

When discussing eMTB motors, it’s easy to get bogged down in semantics. To understand how these metrics actually affect the ride, we’ll provide you with brief and comprehensible summaries of the most important terms you’ll come across in our eMTB motor comparison test.

The torque of an eMTB motor

Expressed in Newton metres (Nm), torque serves to indicate how powerful a motor is. This key figure determines how vigorously the motor propels you forward on the trail. In practice, the amount of torque available is noticeable when pulling away, or when pedalling on steep uphills in heavy gears – i.e. at low pedalling cadences. Once you reach your cruising cadence, all motors operate well below the maximum torque specified by the manufacturers, and it’s factors like maximum power that play a bigger role. The software also plays a critical role, which is why motors sharing the same specified torque can feel very different on the trail. The best example of this is the Bosch Performance Line CX and CX Race motors, which don’t just have the same basic specs, but also rely on largely the same hardware. However, if you switch to Race mode on the CX Race variant, the power delivery is a lot less restrained, while the response is much more direct compared to the standard Bosch Performance Line CX motor.

The power output of eMTB motors

The power output is given in watts (W) and, in the EU, eMTB motors are limited to a continuous rated output of 250 W. However, this doesn’t mean that eMTB motors can’t exceed the 250-watt limit in “short bursts”. As a result, the maximum power output of all the motors on test is well above 250 W, with many of them capable of churning out more than twice that. A motor’s power output is the product of torque and cadence. This means that the power is heavily dependent on the cadence, i.e. how fast you’re pedalling. Furthermore, there’s a distinction between electrical and mechanical power. The electrical power is the power consumed by the motor, while the mechanical power is the one actually transferred to the ground, minus frictional losses incurred by the motor, drivetrain etc. For comparison’s sake, an average rider puts out about 100 watts of power. If you can produce 150 watts consistently, you can already count yourself among the fitter riders. On technical climbs, our test crew managed to push the power metre needle up to the 350 watt mark. A Tour de France rider can generate over 400 watts average power for an hour….

The assistance ratio of eMTB motors

This is the ratio of the motor’s output to the rider’s input. If a motor delivers 100% support, it matches the rider’s input (rider input times 1), effectively doubling the total output at the rear wheel (100 W rider input plus 100 W motor output equals 200 W total output, not considering energy losses in the form of friction and heat). The more powerful a motor is, the bigger the assistance ratio can be. The most powerful motors can put out up to four times the rider’s power and more. However, this is limited by the motor’s maximum power output, which currently hovers at around 600 W for most full-power motors. Once the eMTB motor reaches that limit, it runs out of steam. So, if you’re putting in 200 W with 400% assistance, the motor won’t magically produce 800 W if its maximum output is 600 W.

The pedalling cadence and eMTB motors

Pedalling cadence is measured in revolutions per minute (RPM) and refers to the speed at which you’re pedalling. Although cadence doesn’t get mentioned nearly as often as torque and power in your typical trailhead tech- talk, it has a major influence on both these fancy-sounding factors. As the cadence increases, the torque decreases, while the power increases until it reaches its peak. Cadence also plays a role in the effectiveness and efficiency of the motor. Most motors are only capable of unleashing their full power over a certain range of cadences. The earlier the full power is available, the better for racers and aggressive riders. That said, mellow riders who like to shuttle to the trailhead at lower cadences will benefit from this too – as long as the power delivery is easy to modulate and control. In addition, every motor has an optimal cadence range at which it performs most efficiently. With most motors, this sweet spot starts at around 60 and goes up to 100 RPM. The optimal cadence range has grown with the latest generation of motors – with exceptions like the Bosch SX. Pedalling within the optimal cadence range improves efficiency and effectiveness, resulting in optimal performance. Note: Speeding up your cadence doesn’t mean that you have to pedal harder – you can also downshift into an easier gear to optimise your pedalling speed. In order to call up all the available power, it’s particularly important to pedal within the optimal cadence range of minimal-assist motors! Several of the manufacturers display the current pedalling cadence on the display.

Sustained assistance of eMTB motors

The sustained assistance of an eMTB motor determines how long the motor keeps on churning after you’ve stopped pedalling. Depending on the motor, the length and power of the sustained assistance varies greatly. However, in the EU, the DIN EN standard limits it to two metres. A long sustained assistance is especially useful in technical terrain, allowing you to get up and over obstacles where you can’t pedal continuously. You can also benefit from the sustained assistance in other situations where you’ve got pedal clearance issues. The speed at which the sustained assistance cuts out ultimately affects the bike’s handling: an abrupt stop can feel like you’re hitting a wall, while a smoother fade-out results in a more natural-feeling experience.

The capacity and energy density of ebike batteries

The battery capacity, expressed in watt-hours (Wh), indicates how long a specified amount of power can be drawn from a battery. In theory, a 750 Wh battery could power a motor with a constant electrical power of 750 W for 1 hour. A minimal-assist motor that can draw a maximum of 300 W of electrical power can theoretically consume no more than 300 Wh per hour. In practice, of course, there are additional variables to consider, such as the ambient temperature, complicating an otherwise simple theory. And, as mentioned above, the mechanical output at the rear wheel is a different story altogether.
You’ve got to be careful when comparing the battery capacities of different bikes. The battery capacity must always be considered in relation to the motor and its average power output or consumption. Rather than looking for the biggest battery, it’s important to have the right battery concept for your intended use and bike. A bigger battery is always significantly heavier and considerably more expensive, too – it’s one of the most expensive ebike components. The energy density of the battery results from the battery capacity divided by the battery weight – and there are big differences between manufacturers. A compact battery provides around 200 Wh/kg. This is another one of those interesting figures that cannot be taken at face value. In the end, what really counts is the total weight of the bike and the weight distribution. What is the point of a lightweight battery if it’s hard to integrate and doing so adds unnecessary weight to the frame?

Behind the scenes: How we tested the eMTB motors on the trails and in the lab

Over the past 10 years, our E-MOUNTAINBIKE test crew has tested an incredible number of eMTB motors in a wide variety of bikes, accompanying the development of eMTBs from the very beginning. Accordingly, we’ve gained a wealth of experience over the years, which we were able to and did draw from during this eMTB motor comparison. At the time of testing, for example, we had already ridden the Bosch Performance Line CX motor in over 50 different bikes. We had also tested the still very new TQ HPR50 in 7 different bikes by that time. For a different perspective, we handed all the motors on test over to the renowned Velotech test laboratory in Schweinfurt, Germany, to compare our real-world impressions with lab results. As such, our test procedure was divided into a practical component with a large group of test riders from all walks of life and skill levels, and a theoretical component with the motors undergoing a range of lab tests.

Real-world tests – The most crucial part

To get the most comprehensive review of each system in our eMTB motor group test as possible, we compared the motors head-to-head on a predefined,diverse test track, adding our findings to those we’ve already gathered on various test bikes around the world. That way, we were able to accurately identify even minute differences between the eMTB motors. In preparation for this, we ordered 15 sets of MAXXIS tires, in order to rule out the biggest variable in terms of rolling resistance and traction – the tires. All our test bikes were set up the same way. Our test loop included everything an eMTB’s heart desires: gravel paths, steep chutes, a mix of flowing and technical climbs; up steep ridges, through deep ruts, and down steep drops, as well some stretches of tarmac, because dreams aren’t just made of loam! The eMTB motor systems weren’t spared on the descents either. And we didn’t stop at just testing the riding characteristics – we also focused on connectivity, pressing all the buttons, sliding all the sliders and twisting all the dials in the various tuning apps, using the navigation functions, and connecting other accessories. Our aim was to find the optimal settings and exploit the range of each setting to the full. We’ve rarely had so many emotions so close together while conducting our tests, including everything from amazement and enthusiasm to frustration and disappointment.

Lab tests – The nerdy part

After successfully learning all the terms in our glossary, now comes the experimental part with a few lessons in physics: the laboratory tests. We were able to do this at the renowned Velotech testing laboratory in Schweinfurt, Germany. Velotech are a globally recognised and accredited test laboratory in the field of micro mobility, led by Managing Director Marco Brust. Everything can be tested here: from luggage racks according to DIN EN ISO 11243, to our 13 eMTB motors. Their customers include big names from the eMTB industry, such as Bosch and CUBE. We occupied the lab at Velotech for more than three weeks, sparing no expense or effort in pursuit of the ultimate eMTB motor comparison.

To get as much information from the laboratory tests as possible, we measured both the electrical power and the mechanical power curve of each motor, i.e. how much current the motor draws from the battery during operation, and how much of that energy gets to the rear wheel in the form of mechanical power, minus all losses. We did so at different cadences and differing levels of rider input. The collected data allows us to analyse the eMTB motors’ effectiveness at different cadences, including power delivery, torque curve, efficiency, and any software-based restrictions. The result was about 800 data points per motor, filling acres of spreadsheets. We also conducted range tests to collect further data – but there are too many variables that influence the range for us to be able or willing to publish any kind of general ranking for the various motors on test.

An eMTB motor can churn out great values on the test bench but still not perform accordingly on the trail, since even 800 data points can’t represent reality.

Even if everything sounds nice and scientific in a laboratory, reality often looks very different – usually much messier. Therefore, lab values should be used with extreme caution. Ultimately, what matters is what you can feel and what is relevant on the trail. Especially in the case of eMTBs, the factors influencing the ride feel are incredibly complex and vary greatly. This is more noticeable than with cars, where the drivers and their personal traits and characteristics have a much less significant influence on the handling than riders do astride their eMTBs. Effectively, eMTBs are man/machine hybrids, meaning that they always have to be viewed and tested as such. An eMTB motor can churn out great values on the test bench but still not perform accordingly on the trail, since even 800 data points can’t represent reality. After all, we’re not here to play a game of Top Trumps, we’re here to ride bikes! Just because a motor has a little more torque or power doesn’t necessarily mean it’s better, or that it will actually help you negotiate technical climbs more easily, so instead of showboating with impressive graphs that only reflect half the truth, we used the most important and relevant lab results to substantiate our individual reviews within the appropriate context.

The laboratory test procedure

There are different ways to test motors. For us, there was just one option worth considering: to test the motor system as a whole, i.e. in a complete bike, because that is the most realistic. And we were able to do just that at Velotech! Below, we’ve outlined the lab test procedure for all the nerds amongst us.

To prepare for the laboratory tests, we fitted all bikes with control tires running identical pressures, checked the drivetrains, and lubricated the chains. As a result, the energy losses incurred by the rear wheel and drivetrain should be similar. Then the bikes were clamped to a test rig, which looks a little bit like a big, industrial roller trainer, with a roller resting on the rear wheel. The cranks are turned by an external motor, with a continuously variable speed and power. The speed and power of the external motor simulates the rider’s pedalling power and cadence. Drivetrain losses and rolling resistance can be calculated and accounted for by pedalling the bike with the motor switched off at a certain input power and then measuring how much of that power is transferred to the roller. For practical purposes, however, it’s important to understand that the actual mechanical power put out by the rear wheel is what counts.

First, Velotech project manager and physicist Florian Edelmann helped us determine the power and support ratio of the motors. To do so, the pedals were turned at a fixed cadence while simulating a linearly increasing rider input power, allowing us to measure the electrical and mechanical power. We also had the motors in our eMTB motor comparison set to the highest support mode. Why? Only the highest mode is comparable, because this is where the motor performs at its maximum. All other modes differ from manufacturer to manufacturer, or may be tuned by the bike brand, and therefore don’t allow for an accurate comparison. In addition, the various modes offer numerous customisation options, which makes them even less comparable. The power curves we obtained during this test provide information on how much the electrical and mechanical power output increases, what the ratio is between rider input and motor output, how many watts of rider input are needed for the motor to unleash its maximum power, and, finally, at what power it reaches its limit.

As we learnt in the glossary, both the motor’s performance and efficiency are heavily dependent on cadence. So we did a second test run, in which we tested with a specific, constant rider input power and an increasing cadence. For this, we set the rider’s power quite high at 250 watts, because the previous test showed that every motor unleashes its full power by this point – especially the motors with low support ratios. To cover the complete spectrum for our eMTB motor comparison, we started with a low cadence of 20 RPM and then gradually raised it to a maximum of 120, both of which are extremes at which hardly anyone pedals in reality. While doing so, we again measured the electrical and mechanical power. The results show how much the respective performance depends on the cadence. In other words, at which cadence the motor unleashes its maximum power, is most efficient, and at which cadence the power starts tapering off. In addition, it allowed us to detect the influence of the software: like whether the manufacturer even wants the motor to generate maximum power at a comfortable cadence or whether full power is reserved for those who are willing to put in the effort themselves. We repeated this test with a rider input power of 150 watts, which corresponds to the average power of a relatively fit rider. This test allowed us to draw various conclusions, such as whether an average rider can even manage to call up the motor’s maximum power (without pulling a muscle in the process), and whether riders would perhaps get the same performance from a smaller, less powerful motor without carrying the added weight of full-power models? Finally, which motor provides the most assistance if you want to take it easy yourself?

Details and features: What to look for on an eMTB motor

We already know that choosing the right eMTB system is about far more than the motor’s performance specs and battery capacity. Rather, the overall concept of the eMTB and motor system must suit your intended use and requirements. Nevertheless, there are numerous details and features on the various system components that you should look for.

Which eMTB displays and remotes are right for you?

Just as the grips and pedals serve as the contact points between the rider and the bike, the remote and display are the interface between the rider and the motor system. Depending on the manufacturer, you’ve got a wide range of options: from off-the-shelf products supplied by motor manufacturers, to in-house solutions from bike brands, and third-party products, such as those from system integrators FIT. Top dogs Bosch now offer a whole range of displays and remotes.

The eMTB motor remotes – Push the button

A remote is either your thumb’s best friend or greatest enemy. How friendly or antagonistic the relationship between your thumb and the remote turns out to be depends largely on your subjective needs and expectations. The range of remotes that we’ve fondled is correspondingly wide: including everything from clunky remotes with enough buttons to control a space shuttle, to incredibly minimalistic little levers.

While the minimalist approach usually offers simple operation and an unobtrusive look, extensive remotes usually provide more functions. In the latter case, there’s often just one function assigned per button, and menu items on the display can usually be accessed more directly. They also stand out more on the handlebars and can interfere with the brake and dropper levers, depending on the design. Ergonomics also play a role, because what good is the best remote if you can’t reach it, or only reach it by contorting your hand? Particularly big remotes, like the Bosch LED Remote and the FIT Basic Remote, stick out further from the handlebars than the minimalist TQ and FAZUA remotes, for example. As a result, you’ll have to lift your thumb further away from the grip and press the buttons at an awkward angle, which can be rather uncomfortable. While touring riders have fewer problems with this, it’s especially uncomfortable to remove your thumb further from the grip than absolutely necessary when you’re on the trail – whether you’re riding up or downhill. Remotes with lots of buttons also increase the chances of hitting the wrong button when riding on bumpy terrain, which is a problem you won’t have with small remotes that have just two or three buttons.

The haptics and feedback of the buttons also differ greatly between the different models and brands. While you can never be quite sure whether you’ve actually pressed the buttons on the Yamaha Remote because they have almost zero play, the FIT Basic Remote even provides vibration feedback. In general, a well-defined engagement point with a noticeable amount of smooth play before it, like you get from the Shimano EM800-L remote, feels most natural. Systems that are capable of emitting sound, like that of Specialized, provide additional feedback on the respective action.

The displays of eMTB motors – A minimalist LED or a flat screen TV?

The same applies to displays as to remotes: they’re available in abundance. Large colour displays, small colour displays, integrated displays in the remote, LEDs… You get the drift. Depending on the manufacturer, however, the different variants can be better or worse. TQ manage to provide all the necessary information via a minimalist black and white display in the top tube, whereas Yamaha provide just two rows of LED lights in a chunky block on the handlebar.

With the displays, you must ask yourself how much information you need while riding and how much information you can do without for the sake of a cleaner look and more intuitive operation. Trail-shredders that hang out mainly in their local woods will be fine with a minimalist combination of a small remote and a type of battery level indicator, like the Bosch System Controller or the FAZUA LED display. If, on the other hand, you require navigation on your eMTB and love having access to a wide variety of riding data on the go, you’re better off using a large, feature-rich display. But beware, displays can be a distraction while riding! And besides the type of display, its position is crucial, too. A display that’s positioned in front of the stem remains easily visible while riding, albeit exposed in the event of a crash, and it makes your bike look like a unicorn. The Brose display integrated into the remote ensures one of the cleaner looks in our eMTB motor comparison. One of its drawbacks is that it interferes with the brake lever and, above all, the system start button is positioned between the display and the brake lever, which makes it finicky to operate. For trail riders, integrated displays in the top tube are the most elegant solution, as is standard with TQ, FAZUA, Specialized and DJI.

Charging options for smartphones and other gadgets aboard eMTBs

Whether it’s a smartphone or GPS bike computer, both tend to run out of battery just when you need them most. All the better then that many eMTB motor systems offer integrated charging options, so you can charge your devices while riding. However, you shouldn’t completely rely on this either, because often the charging power is just enough to prevent your smartphone battery from dying while you’re using it to navigate. So, heading out the door with your smartphone battery at just 5% won’t get you very far even with a charging option on your ebike. The position of the charging port plays a major role here, too. You want it close to the head tube, in which case a short cable will suffice to charge your Garmin or smartphone while attached to the stem or handlebar. FAZUA have cleverly integrated a USB-C charging port under the LED display, where it’s within easy reach but well hidden and protected from the elements.

E-mountainbike motor apps – Frustration or joy?

All motors in our eMTB motor comparison have an app, which provides a useful interface with the system. Since these offer a wide variety of approaches and solutions, the question is: what should a good app be capable of? First, it must establish a connection between your smartphone and the eMTB system quickly and easily. Nothing is more annoying than having to jump through hoops or wait forever for the app and your bike to establish a connection. Bike computers or watches can also serve as an interface to the eMTB system, giving you access to additional information – particularly if you’re using a very minimalist display. Moreover, a good app should always let you tune the motor characteristics and customise the support modes. But more on this later.
Over-the-air software updates are a cool feature to keep your eMTB up to date. Systems that don’t yet have this capability can only be updated by plugging the bike into your laptop or taking it to a dealer, which is a hassle. All these functions, if properly implemented, already make a good app, providing everything you need. It’s also important that it takes just ONE app, so that you don’t have to switch between several apps for different functions or install other apps or add-ons to establish a connection.

In addition to these basic functions of a good app, some manufacturers offer additional features that, if implemented well, can expand the range of functions significantly. Navigation that includes an estimate of the range based on the route, its elevation profile, and the motor’s energy consumption can be immensely helpful when planning your route. At best, these work in combination with turn by turn instructions on the display. Being able to link it with platforms like Komoot and Strava is a plus, allowing you to directly synchronise your routes and ride data. Fun stats can also be a hit with your buddies while sipping on a well-deserved post-ride brew. For example, Specialized allow you to track your jump stats to see how much time you spent in the air during a ride. That way you can quickly put an end to the discussion about who collected the most airtime. The Bosch eBike Lock function and the Specialized System Lock provide added peace of mind in day-to-day life when leaving your bike parked outside or stopping for refreshments after a long day in the saddle. These functions let you disable the motor in the app, so thieves can’t just ride away with your bike in Turbo mode. However, it’s only the motor that’s disabled, so the eMTB can still be ridden like an analogue bike. Bosch go one step further with the ConnectModule: it allows you to track the location of your bike via the app, and can emit an alarm when the bike gets moved. However, you also need a paid subscription to unlock the function in the Bosch eBike Flow app. DJI’s comprehensive app allows you to customise several parameters of the riding modes, such as torque, the duration of the sustained assistance, pedal sensitivity and start-off power, and to display statistics from your tracked rides. The implemented GPS tracking function also lets you track your bike and customise the look of your touch display with countless functions. And all this in a user-friendly interface. However, this is just the tip of the iceberg, and DJI offer significantly more features than the competition with their app.

Different riding modes and customizability of the eMTB motors

Linear or dynamic e-mountainbike support modes?

The motor manufacturers in this test offer three to five different support modes as standard. In principle, the support modes can be divided into two categories, according to the type of support: dynamic and linear. Dynamic support modes adapt to the riding situation, meaning that the motor adjusts its support depending on the incline, cadence, or force applied to the pedals. Dynamic support modes provide a natural ride feel on level ground, where little support is needed, while letting the motor kick into high gear when you need it most, like on a steep, technical climb. By now, most high-quality motor systems come with one or more dynamic modes, with the most well-known probably being Bosch’s E-MTB mode. Linear modes, on the other hand, do not adapt the eMTB motor’s output according to the input or riding situation. Thus, they offer a fixed support ratio at which the support increases linearly with increased input.

Customizability of the ebike motor support modes

Most eMTB motor manufacturers allow you to customise the various support modes via an app. The adjustability varies greatly between the different motor systems. Some manufacturers, like Brose, offer just one dial per support mode, allowing you to adjust the intensity of each mode. With the Micro Adjust function, Specialized let you do this directly via the remote, even while riding. Other manufacturers take it a step further still. With Bosch, the support and dynamics of all modes can be adjusted from -5 to +5 in the eBike Flow app. In other words, it’s not just the intensity of the support that can be adjusted, but also the way it kicks in. In addition, you can set the maximum speed up to which a mode offers support, and the maximum torque. Specialized follow a similar path, allowing you to adjust four parameters in every support mode. The manufacturers in our eMTB motor comparison test also showed differences in the extent to which the modes can be adjusted. Bosch have a predefined framework within which adjustments can be made. Brose, on the other hand, let you drag the adjuster from 0 to 100 in any mode, so you can turn Eco mode into Turbo mode and vice versa. The FAZUA system is similarly unrestricted, even allowing you to configure entirely new personalised modes. Shimano take it to a whole other level with theirFine Tune mode, which gives you the option of configuring up to 15 individual support modes. It’s not just in their range of functions that the manufacturers differ, but also in clarity and user-friendliness. Regarding custom support modes and fine tuning, it’s up to you to decide how far you want to dive down this rabbit hole, or whether you’d be happy with the existing modes as they are and prefer to spend your time on the trails instead of fiddling with dials on a screen.

E-mountainbike batteries – An overview of the different battery concepts

Basically, the battery concepts of manufacturers can be categorised as monolithic or modular. The classic configuration is monolithic, where you’ve got one battery integrated on the bike, serving as your only power source. Most of the integrated batteries in the down tubes are removable, which offers advantages when transporting the eMTB, and allows you to take the battery indoors for charging. However, there are big differences in the battery covers and locking mechanisms used. Other batteries are permanently integrated, meaning they can’t be removed. With a modular system, the battery capacity can be expanded. This is done with range extenders – external batteries that attach externally to the frame and plug into the charging port. Range extenders vary in size from manufacturer to manufacturer, but they always function as an extension of the main battery. They usually attach to the bottle cage or a specially designed bracket, and connect to the main battery. The advantage of a modular system is that you can expand the battery capacity as needed. If you typically ride shorter routes and get along well with a smaller battery, but don’t want to miss out on longer rides at the weekend, you can simply up the capacity with a range extender and off you go. As a result, you don’t have to carry around unnecessary battery capacity and therefore weight on your post-work jaunts. In our eMTB motor comparison, the minimal-assist motors from TQ, Specialized, and Bosch all have the option of a range extender, but so do the full-power systems from GIANT and Pinion. In theory, some motors such as the Specialized SL 1.2 and the Bosch SX, can be powered solely by a range extender, without the main battery.

E-mountainbike battery durability – Service life, charging cycles, and storage

Manufacturers merely provide indications of the lifespan of eMTB batteries. Each battery has a specified number of charging cycles after which a certain % of residual capacity remains usable. That said, this information only serves as a rough guideline, and it’s difficult to prove or grasp in realistic terms. However, as a general rule of thumb, it can be said that bigger batteries should have a longer service life. On the one hand, this is simply because larger batteries don’t need to be charged as often – fewer charging cycles mean that the cell chemistry of the batteries is less affected. On the other hand, the bigger capacity allows you to keep the state of charge ranging between 30% and 80%, which is gentler on the battery. That said, no eMTB battery is exempt from wear and tear, unfortunately. Depending on the manufacturer and battery, the number of charging cycles that a battery will put up with varies. In most cases, however, you can expect to get between 500 and 1,000 charging cycles. If you ride your eMTB three times a week, fully draining and recharging the battery every time – that is, one full charging cycle per ride – the battery’s service life is just over 3 years, assuming the worst-case scenario of 500 charging cycles. However, even if this were the case, most batteries still have a decent amount of usable capacity remaining. In addition, the battery service life can be prolonged with the appropriate care: if you only recharge it halfway, you only use half a charging cycle. Furthermore, the storage of your battery also determines the speed at which it deteriorates. E-mountainbike batteries don’t like getting very hot or cold, with the ideal temperature ranging between 10°C and 20°C, so it is best not to store the battery in the garden shed when you’ve got frost or very high temperatures. If you’re not going to use your eMTB for a long time, like in the winter, make sure that the battery level doesn’t fall below 30%. Batteries don’t like being stored almost empty. While this is good general advice, you should always try to follow the manufacturer’s recommendations on storage and charging of your particular battery.

Market maturity and service network of eMTB motors

As described at the beginning, the development speed of eMTBs and especially eMTB motors is incredibly high. Unfortunately, this also results in products being introduced to the market prematurely, leaving customers to contend with all kinds of teething issues. We also got a taste of that in our big eMTB group test. Above all, we struggled with various issues still plaguing the new minimal-assist eMTB motor systems. In particular, FAZUA’s software has had various bugs since its launch in 2022. So, buying a newly launched eMTB motor can come with certain risks. And some of these problems are actually structural in nature, which, though they can be mitigated to an extent, can rarely be remedied completely. For example, the Brose Drive S Mag long had problems with the internal belt. Fortunately, the internals of the Brose motor have been slightly modified since that first faulty generation and the software has been improved, too, so the technical issues have been largely dealt with. Incidentally, the newly introduced Brose Drive³ Peak dispenses with the belt.

With the above in mind, it’s all the more important to be able to rely on a large and competent service and dealer network. After all, what good is the latest eMTB motor system if you run into a technical issue while on holiday but the closest service partner is on another continent? The likes of Bosch and Shimano have a very extensive network of dealers and service partners. In general, the bigger and more widely distributed a motor brand is, the better the chances of getting help at home or on holiday in the event of a defect.

Conclusions: high-performance maths to find the right bike

In the single motor reviews, you’ll find all relevant information and detailed insights into each motor system, with all its strengths, weaknesses, and potential. Although the overall design of a bike is what really matters, it’s always worth taking a closer look at all the motors currently available on the market to avoid unpleasant surprises and get the most value for your money! After all, there’s a second, highly mathematical equation to consider: great bike + bad motor = bad bike! In this context, “bad” doesn’t necessarily refer to motor performance; it can also refer to anything that can get you stranded in the woods, like an unreliable system, vulnerable components, or poor service and spare parts availability in your country. So, make sure to stay well-informed and make the right purchasing decision. We’ve got your back and are committed to providing you with honest information and essential background insights!

As the contact points of a bike, the handlebars, saddle, and pedals of a bike have to fit like a glove – one you’d be happy to wear all day. Just as important as the pedals are the shoes you wear to complement them. After all, you wouldn’t bomb down a trail in flip-flops! Two Swiss founders came to the same conclusion, and in 2007, they launched Suplest to take cycling shoes to the next level. Originally focusing on road shoes, Suplest now also manufacture mountain bike shoes and lifestyle sneakers.

“Check out my new shoes!” hollers tester Manne while walking through the front door with a big grin on his face, showing off his brand-new Suplest Flatpedal MTB shoes. And he’s not wrong – the 2022 Flatpedal Sport certainly catches the eye. With its understated design, the Suplest Flatpedal Sport features black and grey microfiber with synthetic leather sections and red accents on the eyelets and the pull loop on the tongue.

The Suplest Flatpedal Sport shoes are available in two colours, black and yellow-brown, which both retail at around €130. One of the first things you’ll notice is the lacing system – or rather, you won’t notice it at all, as it’s hidden under a neoprene cover. The cover is there to tuck the laces away, preventing them from catching in the drivetrain, which has caused many crashes in the past. The Flatpedal Sport features the BEARPAW 5 sole made from SUPtraction rubber, which is also designed in Switzerland. Together with the knobby tread, it promises superb grip both on the pedal pins and on the ground. So, how did the shoes perform in our test?

On the trail and in the office – Suplest Flatpedal Sport MTB shoes on test

After Manne showed off his new shoes in the office, we couldn’t wait to see how they performed on the trail. The Suplest MTB shoes are easy to slip on and fit snugly right from the start – even before tightening the laces. The front of the shoe is reinforced with a stiff rubber toe cap, and there’s excellent padding around the ankle, ensuring the shoes fit securely without being too tight. Even after a full day in the office, Manne had no pressure points, nor did he after several consecutive days of long eMTB tours in the Dolomites.

The roomy toe box makes these MTB shoes ideal for riders with wide feet. Plus, the breathable material ensures your feet don’t overheat – unless it’s 35°C outside, in which case, you’re going to sweat regardless of your choice of footwear!

On the pedals, the SUPtraction rubber sole of the Flatpedal Sport provides a solid connection with the pedal pins. The grip is so strong that you need to consciously lift your foot to adjust your position – just as it should be. The stiff sole ensures excellent power transfer to the pedals while remaining flexible enough for comfortable walking. This means you don’t feel like you’re clomping around in ski boots on the way to a scenic viewpoint. And the knobby tread doesn’t act as a dirt magnet, so you don’t need to swap your shoes when you get to the office after your commute. And the comfortable sole also making those five daily trips to the coffee machine no problem at all in these shoes.

Manne’s tip: buy the shoes a size larger than usual – feet tend to swell by the evening!

Conclusion about the Suplest Faltpedal Sport

The Suplest Flatpedal Sport MTB shoes impressed us above all with their BEARPAW 5 sole, which offers great grip both on the pedals and on the ground. We’re pretty fond of the overall comfort feeling too, even when just walking around the office. Highlights include the snug fit, reinforced toe cap and ankle protection, and breathable materials. The shoes remain comfortable, even on longer rides. For €129,99, you’ll get a solid pair of MTB shoes that can handle the trail while still looking good for everyday use.
