Designed specifically for riders utilizing Bosch and DJI motor systems, these cranks provide a robust upgrade for those navigating rowdy terrain.

Yes, you will need a standard crank puller tool and a torque wrench to safely secure the arms to the motor spindle.
The set includes pedal washers, but you will need the specific crank bolts provided with your motor system and the necessary shop tools for assembly.
Check your bike's original crank length. If you do significant technical riding, shorter cranks like the 160mm or 165mm help reduce pedal strikes.
Verify the mounting bolt is torqued to the manufacturer's specified value and that the crank was fully seated on the spindle before tightening.
Remove the pedals, clean the threads, apply a light layer of grease, and reinstall with the included washers to ensure a tight, quiet interface.
Installation requires a specific crank puller and a torque wrench to ensure the arm is properly seated on the Bosch or DJI motor spindle. Always verify that you are using the correct length (160mm, 165mm, or 170mm) for your specific frame geometry to avoid pedal strikes. Regarding care, regularly inspect the pedal interface for any signs of loosening, and ensure the mounting bolts are torqued to the manufacturer's specifications. Clean the crank arms with mild soap and water, avoiding high-pressure washers that can force contaminants into the motor seals.
