Bosch Performance Line CX motor

Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

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 dont have to worry about dropping it thanks to a secondary safety catch.

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 youre hitting big features and dont want to bottom-out, or when you want to run a coil shock.

Transition to transmission

SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system thats not only cleaner looking, its also more precise under load, and easier to set up.

Bosch System Controller

The System Controller gives you a quick overview of your assist mode and battery level without distracting you from the ride. Its integrated into the top tube so its out of the way but still easy to see with LED indicators. It also connects to the eBike Flow app via Bluetooth for accessing ride stats and performing system updates.
