It's right for you if...
You want to get out and explore more trails. 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 aluminum frame that fully encases a long-range 500Wh battery, a powerful Bosch Performance CX (250Wh, 85 Nm) motor that helps you sustain speeds of up to 20 mph or 32 km/h, and an ergonomic Purion controller. Plus, a 120mm suspension fork, 100mm of rear travel, a 10-speed Shimano drivetrain, and a dropper post.
The final word
This full suspension e-MTB is comfortable, efficient, and fast on rough terrain. The powerful Bosch electric drive system makes it possible to tackle any climb you encounter and adventure farther than ever.
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
- 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
- The Purion controller has Walk Assist and an intelligent eMTB 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. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits—29˝ wheels on larger frames, 27.5˝ wheels on smaller frames

Bosch Performance Line CX motor
Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.
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.
Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure—no more error codes from mis-aligned sensors.
The bike is already internally wired to accept additional lights. Go to your dealer and simply have them attached to the bike and plug them in.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
Bosch Purion Display
Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator, and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with handlebars.

Sizing & Tech
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.
