Bosch Performance Line CX motor: 100 Nm upgrade ready

New RIB 2.0

Bosch Mini Remote
The compact, ergonomic Mini Remote lets you easily change assist level, activate Walk mode, or turn on optional lights, all without moving your hand off the handlebar. Plus, it's wireless and connects with your System Controller via Bluetooth

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

Adjust the suss for full send
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.
