New motor, new chapter: Trek present two new eMTBs for the 2025 season, which both come equipped with the latest Bosch Performance Line CX motor. The Trek Rail+ and Trek Powerfly+ are designed to cover a wide range of applications, from trekking to trail riding. Here you’ll find out everything about the bikes!
Since its founding in 1976, the American bike manufacturer has steadily become a key player in the cycling world. With a wide range of products, including road bikes, mountain bikes, and kids’ bikes, and the backing of numerous racing teams across various bike disciplines, Trek have gained global recognition. In the e-mountainbike segment, the American brand is now launching two new models for the 2025 season, coinciding with the release of the latest Bosch Performance Line CX motor: the Trek Rail+ and Trek Powerfly+. Each bike is aimed at a different target group: the fully suspended Rail+ is designed for trail riders who prefer challenging descents and technical terrain. The Powerfly+, on the other hand, was developed for touring riders and adventurers seeking a versatile ebike for both on- and off-trail use. The Powerfly+ is available as a hardtail and a full-suspension bike, with additional models featuring mudguards and lights to make the bike suitable for everyday use.
We’ve put together a quick overview of the new bikes for you.
The new Trek Rail+ 2025
All eight versions of the Rail+ come equipped with the new Bosch Performance Line CX motor and a 800 Wh Bosch PowerTube battery. The drive is paired with a Bosch Mini Remote and Bosch System Controller on all models. The Rail+ is also compatible with the Bosch Range Extender.
The Rail+ 5 and Rail+ 8 rely on an aluminium frame, while the Rail+ 9.7, Rail+ 9.8 XT, Rail+ 9.8 GXS AXS, and the Rail+ X0 AXS, along with the Rail+ 9.9 XX AXS flagship model, feature a carbon frame. Prices for the Trek Rail+ start at € 5,499 for the Rail+ 5 version, going up to € 12,999 for the top-tier model.
The Trek Rail+ 9.9 XX AXS flagship model features a 160 mm RockShox ZEB Ultimate fork and the matching RockShox Super Deluxe Ultimate RC2T shock, also generating 160 mm of travel. The wireless SRAM XX Eagle AXS drivetrain ensures precise shifting, while the SRAM MAVEN Ultimate four-piston brakes with 200 mm rotors provide powerful, reliable deceleration. Additionally, the Rail+ comes with a mullet wheel setup (29″ front, 27.5″ rear), except for the size S frame, which uses 27.5″ wheels both front and rear. The bike is available in sizes S, M, L, and XL, and retails at €12,999.
2025 Trek Powerfly+ hardtail
The Trek Powerfly+ Hardtail is available in four configurations, with prices ranging from € 3,299 for the entry-level model to € 4,999 for the top-tier version. All models come with aluminium frames and 29” wheels, except for size S, which rolls on 27.5” wheels. The Powerfly+ 4 and Powerfly+ 4EQ rely on a 600 Wh battery, while the Powerfly+ 6 and Powerfly+ 8 flagship model use a bigger 800 Wh battery.
The Trek Powerfly+ 8 EU is the flagship model in the Powerfly+ Hardtail series and, like all models in the range, it comes with an aluminium frame that integrates the powerful 800 Wh Bosch PowerTube battery. It rolls on 29” wheels and features the new Bosch Kiox 300 display, while the optional 250 Wh Bosch Range Extender allows you to expand the battery capacity to a whopping 1050 Wh.
With its 12-speed Shimano XT DEORE drivetrain and Shimano DEORE four-piston brakes with 200 mm rotors, it’s specced to handle any trail – at least according to the manufacturer. FOX supply the 120 mm FOX 34 AWL fork.
2025 Trek Powerfly+ FS
The Trek Powerfly+ FS comes with the same battery options and wheel sizes as the hardtail version. The Powerfly+ full-suspension models are also compatible with the Bosch Range Extender. Prices for the Powerfly FS+ range between € 4,499 and € 6,999.
The Trek Powerfly FS+ 8 is the flagship model in the Powerfly+ FS range. It features an integrated 800 Wh battery and an alloy frame, while a new Bosch Performance Line CX motor provides powerful assistance. The motor is paired with a Bosch Kiox 300 display. The suspension consists of a 130 mm FOX Rhythm 36 fork and 120 mm FOX FLOAT Rhythm shock. A wireless SRAM GX Eagle AXS Transmission drivetrain ensures smooth shifting, while SRAM DB 8 four-piston brakes with 200 mm rotors do stopping duties.
Trek’s new e-mountain bike models cover a broad range of uses. With various configurations, the Powerfly+ is designed to be ideal for trekking and touring. Meanwhile, the new Rail+ is aimed at sporty riders who frequently tackle technical terrain. We’re especially keen to see how the mullet wheel setup impacts the bike’s performance. Both bikes look very promising, and we can’t wait to get our hands on them for testing to see how they perform on trails and long rides. Stay tuned for our full review!
