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.

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.

You get a 29" front wheel for monster truckin' over stuff, with a smaller 27.5" wheel out back for getting rowdy.

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.

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 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.

Learn more

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.

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.

See the guide

This suspension calculator will help you optimise your suspension settings for your riding weight. Simply follow the steps to find your best set up.

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 more

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.

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.

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.

We reserve the right to make changes to the product information contained on this site at any time without notice, including with respect to equipment, specifications, models, colours, materials and pricing. Due to supply chain issues, compatible parts may be substituted at any time without notice. The prices shown are the manufacturer's suggested retail prices.

Bike and frame weights are based on pre-production painted frames at time of publication. Weights may vary in final production.

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
