FSA CK-220 Bosch Gen4 E-Bike Crankarms Keep the Power Flowing E-bike drivetrains put more torque through the cranks than a rider's legs ever could alone, and the arms have to keep up. The CK-220 uses diecast aluminum construction to handle that load without adding unnecessary weight to a bike that already tips the scales. The ISIS drive interface connects cleanly to the motor spindle, and a range of arm lengths lets you dial in the fit for the rider on the bike. If you're running a Bosch Gen4 motor and need a replacement armset that just works, this is it.
