Rotor eKAPIC Crank Arms for Bosch

Rotor has designed the eKAPIC crank arms specifically for E-MTBs with a fourth-generation Bosch motor. They are made of aluminium and, thanks to Trinity Drilling technology, are characterised by their low weight in relation to their stiffness. The low Q-factor of 171 mm ensures natural, knee-friendly pedalling that feels like riding a bike without electric drive.

Guidelines for Replacing E-bike Components:

Before you replace components on your e-bike, please read through the guidelines for component replacement for CE-marked e-bikes/pedelecs with pedal assistance.

Bosch Direct Mount

Technical Information:

Series:

KAPIC

Crank Arm Material:

aluminium (6082)

Crank Arm Length:

170.0 mm, 175.0 mm

Q-Factor:

171 mm

Recommended Bottom Bracket:

ISIS Drive

Compatibility:

• E-Bikes with Bosch Gen4 motor
• frame width (measured at a distance of 17 cm behind the centre of the crank axle) plus 4 cm (2 cm for each side) must be less than 17.1 cm (= Q-factor)

Features:

• forged and CNC-machined aluminium
• low weight with high stiffness
• low Q-factor, similar to a bike without motor, for pedalling that is easy on the knees and hips

Technology:

Aluminium CNC
Computer Numerical Control (CNC) milling ensures a precise and uniform production process. This is particularly important when manufacturing components that must function properly and work in congruity with other parts. Thanks to state-of-the-art CNC equipment, Rotor parts are manufactured with extreme precision, down to a hundredth of a millimetre.

TDS
Rotor CNC cranks have a particularly high stiffness due to the Trinity Drilling System (TDS). In this procedure, three full holes are drilled from the bottom bracket to the pedal. This creates a box-like grid, similar to a box girder bridge. This makes the cranks extremely stiff while at the same time reducing weight, resulting in an excellent stiffness-to-weight ratio.
