By placing torque detection around the input structure, this e-bike drive layout simplifies sensor interconnection and saves internal space.
An overlapping torque sensor and detection target free axial space in an e-bike drive unit while simplifying connections and preserving sensing accuracy.
Overlapping torque and rotation sensing in an e-bike drive unit saves axial space, simplifies interconnections, and keeps detection accurate.
A detection shaft sleeve and one-way bearings isolate torque sensing from chain-wheel drive, improving assist output accuracy and stability.
