You want to get out and explore more trails. Moreover, you’re looking for an e-MTB with trail-smoothing full suspension and the reliable, leg-boosting power of an electric drive system made specifically for the demands of off-road riding.
The tech you get
A durable aluminium frame that fully encases a long-range 500 Wh battery is a key feature. Moreover, the latest from Bosch with smart system Performance Line CX motor, capable of speeds up to 20 mph (25 km/h in Europe), including the new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app, adds to the bike’s capabilities. Additionally, the 120 mm suspension fork, 100 mm of rear travel, a 10-speed Shimano drivetrain and a dropper post make this an impressive package for off-road adventures.
Why you’ll love it
- For e-MTB, full suspension is a game-changer: it soaks up rugged terrain so you can ride the Bosch pedal-assist smart system to its full potential
- Trek’s Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy to remove the battery without tools and lets you mount a water bottle cage – even on full suspension e-MTBs
- The dropper post lets you lower your saddle on the fly so it’s out of the way on descents
- It comes equipped with Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
- Powerfly FS frames feature a curved top tube that makes standing over the bike easier. Additionally, Smart Wheel Sizing means you’ll get the fastest wheel that fits – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.

* All specifications listed are subject to change without notice. Please note that manufacturer component substitution changes may impact our specifications. These changes are caused by high global demand for bikes and resulting supply chain issues in the bike industry. Furthermore, we recommend confirming the specifications with your local Evo Cycles showroom if you have any questions.
Bike Weight: Many brands strive to list the lowest possible weight, but in reality weight can vary based on frame size, finish, hardware and accessories. The most accurate way to determine any bike’s weight is to have your local showroom weigh it for you. Ultimately, this is the best approach, as bike weights can vary even between the same model due to component choices and customizations.
