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
The Bosch Performance Line CX sets the standard for Trek 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.
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 eBike Flow app
The new eBike Flow app turns your Trek full suspension electric mountain bike 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.
