One of the biggest names in the business. Our e-cranks for Bosch motors work on their ISIS splined “Performance Line” of e-motors. The arms are smartly shaped specifically for more efficient pedalling plus optimum clearance. Perfect for any Bosch equipped e-bike whether for urban, trekking, or mountain.

These cranks are ISIS fit for Bosch Performance, Performance CX and older type Active Line. They will not fit the 2018 Active Line / Active Line Plus motor which uses the smaller Bosch BNI Interface.
