Removable Integrated Battery
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.
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.
Bosch LED Remote
The Bosch smart system LED remote lets you easily change assist modes, activate walk mode, or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.
Bosch Smart System
Bosch smart system gives you an eMTB that's more connected than ever. The LED remote connects with Bosch eBike Flow app so you can get ride stats, adjust settings, and perform system updates. Plus, Bluetooth connectivity makes it easy to add a display if you want to make it easier to see your ride data.
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 personalized experience. Use it to customize your motor's assist behavior, 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.

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.

Learn moreComplete Tubeless System
Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right 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.
