Is this chainring compatible with my Bosch motor?

This chainring fits Bosch generation 4 motors with a 52mm chainline (KL52) and Bosch generation 5 motors with a 54mm chainline. Check your motor’s generation before ordering to ensure a correct fit, as G4 and G5 systems use different chainline specifications.

Why choose a steel chainring over other materials?

Steel offers superior strength and wear resistance, making it ideal for the high torque output of e-bike mid-motors. While slightly heavier than aluminum options, steel chainrings typically last longer under the repeated stress of daily e-bike riding, making them a reliable choice for demanding use.

Is this an original Bosch part or an aftermarket replacement?

This is a Miranda-branded aftermarket chainring, specifically engineered to match Bosch G4/G5 chainline specifications. It serves as a durable, compatible replacement for worn or damaged original chainrings, supplied via Kruitbosch.
