For measurement of torque (pedal force), rotational number and rotational direction we have developed a compact BB cartridge especially for E-bikes.

By means of the signals of the BB cartridge torque sensor the electric motor enables the biker to keep constant pedalling force, either by upwards or downwards riding, as well as by riding against the wind. This way the biker can enjoy maximal comfort and it also guaranties efficient use of the battery capacity.

The BB cartridge torque sensor is available in all its variations at the company Thun.
