Bosch Performance Line CX motor
The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.
New RIB 2.0
Removable Integrated Battery (RIB 2.0) makes it easy to remove your battery for more convenient charging or travelling, and you don’t have to worry about dropping it thanks to a secondary safety catch.
Mixed wheel size
You get a 29" front wheel for monster truckin' over stuff, with a smaller 27.5" wheel out back for getting rowdy.
Adjust the suss for full send
Adjust the leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you're hitting big features and don’t want to bottom-out, or when you want to run a coil shock.
Bosch System Controller
The System Controller gives you a quick overview of your assist mode and battery level without distracting you from the ride. It's integrated into the top tube so it's out of the way but still easy to see with LED indicators. It also connects to the eBike Flow app via Bluetooth for accessing ride stats and performing system updates.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
Bosch eBike Flow app and associated features are not available in all markets. Check with your local Trek retailer for details.
Shimano XT
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.

This suspension calculator will help you optimise your suspension settings for your riding weight. Simply follow the steps to find your best set up.
Learn moreComplete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.
Learn moreIntegrated 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.
Oversized 34.9mm dropper post
Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.
Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
