eKapic Crank Arms Polini® QF 174

The ROTOR eKapic Crank Arms Polini® QF 174 are not just another crank adapted eBikes, are cranks designed by and for eMTB. These 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.

These cranks are 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. The TDS removes excess material from the crank arm, resulting in a lighter crank without compromising its stiffness-to-weight ratio.

Among its many features, the eKAPIC has one that’s immune to marketing hyperbole: a narrow Q-factor. The use of a narrow Q-factor gives you a pedaling position similar to that of a human-powered bicycle, which has been perfected for more than a century. The eKAPIC’s narrow Q-factor allows the rider to go off-road without risking biomechanical damage from awkward pedaling.
