This internal steel gear for the Bafang BBSHD motor is a key component of the mid-drive motor's transmission system. It transmits torque between the motor's various internal components, ensuring smooth, precise, and durable operation.
Unlike nylon sprockets, this high-strength steel version is designed to withstand heavy loads and intensive use, particularly on powerful motors such as the BBSHD. It offers excellent durability and enhanced wear resistance.
Ideal for engine repairs or overhauls, this pinion gear restores the system’s original performance and reliability.
