    摘要： A torque sensor for a bicycle includes a coil. The torque sensor may include a support that is disposable around a device of the bicycle, such that the support and the device of the bicycle are separated by an air gap. The torque sensor may also include an excitation coil supported by the support, and a sense coil supported by the support at a distance away from the excitation coil in an axial direction of the support. The excitation coil is configured to induce a voltage and/or current in the sense coil via the device of the bicycle when the support is disposed around the device of the bicycle. The induced voltage is related to a torque in the device.

    摘要： An electric device suitable for a bicycle is disclosed. Said electric pedal device includes a housing (10) configured to form a space therein, a rotating shaft (20) passes through both ends of the housing, a reduction gear set (30) configured to reduce a rotational force of the rotating shaft, a rotor (40) configured to rotate by an output of the reduction gear set, a stator (50) including a winding around core laminations (120) and a hub (100). Wherein said core laminations are coupled to the hub while prevented by a structure that an axial deviation relative to the hub is possible. Further a print circuit board (60), controlling the electric power to the stator, is fixed to said housing.
