Abstract
A torque sensor includes a contact sensor and a contactless sensor. An electric drive system for a bicycle includes an electric motor having a rotor rotatable about an axis. An output component is coupled to the electric motor and is rotatable about an axis. An input component is rotatable about the axis and is concentric with the output component and the rotor. A one-way clutch is disposed between the input component and output component. The contact sensor is coupled to the output component. The contact sensor is configured to measure a torque applied to the output component by the input component and provide an input signal. The contactless sensor is disposed between the output component and a fixed component. The contactless sensor is configured to provide an output signal proportional to the input signal
