Bosch Performance Line CX motor: 100Nm upgrade ready

Bosch Performance Line CX sets the standard for eMTB performance with 85Nm of torque out of the box, but can be tuned all the way up to 100Nm and 750 watts of power using the Bosch eBike Flow app. The Bosch Smart system also has intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain. *O aplicativo eBike Flow não está disponível no Brasil.

New RIB 2.0

Removable Integrated Battery (RIB 2.0) makes it easy to remove your battery for more convenient charging or traveling, and you don't have to worry about dropping it thanks to a secondary safety catch.

Extend your ride

Wanna take your ride even farther? Pair a 250Wh PowerMore range extender with your bike to chase your most epic adventures.

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 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.
