This reinforced 36-tooth planetary gear is a critical transmission component designed for Bafang electric bike motors with power ratings of 250 W, 500 W, and 750 W, particularly hub motors. It transmits torque between the rotor and the wheel, ensuring smooth, quiet, and efficient operation.
Made from high-strength nylon and steel alloy, this sprocket significantly reduces noise and vibration while protecting the motor’s internal components. It is an ideal solution for repairing, maintaining, or refurbishing an e-bike motor that shows signs of wear or a loss of performance.
