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 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.
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.
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.

Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
