Bafang Torque Sensor Bottom Bracket 73mm

⚙️ Bafang Torque Sensor 73mm — smooth pedal assist for compatible e-bikes

Bafang Torque Sensor Bottom Bracket 73mm is an original Bafang replacement torque sensor designed for compatible torque-based electric bike systems. It measures real rider effort at the bottom bracket and helps the controller deliver smoother, more natural motor assistance.

Unlike a basic cadence sensor that mainly detects pedal rotation, a torque sensor reacts to how hard the rider actually pushes on the pedals. The result is more progressive assistance, better control when starting, a more natural ride feel and improved response on climbs or uneven terrain.
