Bicycle drive assembly for operating with an integrated torque sensor and a supplementary drive motor includes an electromagnetic servo backing in a structure parallel to pedal bearings.

摘要

An intermediate shaft for measuring torque remains engaged in an inside bearing shaft (6) connected to an internal geared wheel or chain and turns in the same direction as the inside bearing shaft. This intermediate shaft fits on the inside bearing but is not centered on the inside bearing's axis and also forms a driven shaft. A cylinder gear is pressed onto a sensor shaft (4) and engages in the internal geared wheel.
