FSA CK-220/IS 170 mm Crankarms for Bosch Gen4 E-Bike
The FSA CK-220/IS crankarms in 170 mm are designed for E-Bike applications with an ISIS interface and are compatible with Bosch Gen4 motor systems. The construction uses die-cast aluminum arms, a solution designed to ensure stiffness and durability in electric bike use. The 170 mm e-bike crankarms are a specific replacement for configurations that require this length and coupling standard.
ISIS interface and compatibility with E-Bike motors
The ISIS Drive system defines the interface between the crankarm and the motor axle and must match the standard used by the drive unit installed on the bike. In addition to Bosch systems, the CK-220/IS range is also indicated by FSA for specific Brose, Yamaha, and Avinox applications. The Bosch Gen4 crankarms must therefore be selected by checking both the ISIS interface and the length required by the original E-Bike setup.
Die-cast aluminum arms for E-Bike use
The arms are made from die-cast aluminum and feature a black finish with printed graphics. The 170 mm length determines the pedal stroke radius and must be maintained when replicating the bike's original setup. The 324-0054003230 code precisely identifies this variant, distinguishing it from CK-220/IS versions available in other crank lengths.
