Drivetrains on E-Bikes with strong mid motors are subject to enormous constant load. Based on that fact, KMC offer specific E-Bike chains and sprockets for BOSCH motors and internal gear hubs.
Specifically designed for BOSCH E-Bike systems, the KMC Narrow chainring is a perfect solution for replacing or upgrading your current front sprocket. By incorporating KMC into your drive train you can vastly increase useage and ensure a mileage of over 3,500km.
