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
The 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.
