The tech you get
A durable aluminium frame that fully encases a long-range 625 Wh battery, a powerful Bosch Performance CX (250 Wh, 85 Nm) motor that helps you sustain speeds of up to 25 km/h and a Kiox controller. Plus, a RockShox Gold RL 120 mm suspension fork, 100mm of rear travel with a RockShox SIDLuxe Select+ shock, powerful 4-piston hydraulic brakes, Bontrager Line Comp 30 wheels, a 12-speed Shimano drive train and a dropper post.
The final word
This full suspension e-MTB is a blast to ride. It has upgraded suspension, brakes, wheels and more that can help you reach new destinations on the trail.
favorite_borderWhy 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 system to its full potential
- The dropper post lets you lower your saddle on the fly so it's out of the way on descents
- Wide Line Comp 30 wheels provide more tyre support for better traction and control, and they come completely tubeless to save weight and prevent flats
- The full-colour Kiox controller displays ride info, connects with your Bluetooth-enabled devices and has a built-in theft prevention feature
- 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
E-MTB Category Winner

Features
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.
Custom eMTB Lite mode
Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
