Rotor eKapic crank arms for Bosch GEN4 QF171.
A real eMTB experience. Lightweight, aluminum cranks compatible with Bosch®, Brose®, Fazua®, and Polini® motors. The new dedicated eMTB cranks have evolved the technology, engineering, and design from ROTOR’s existing range of mountain bike cranks to produce the eKAPIC crankset adapted specifically to e-mountain bikes.
The eKAPIC is crafted out of forged and CNC’d 6082 aluminum, and features ROTOR’s Trinity Drilling System, which is a process that drills three full-depth holes along the axis of the crank.
