Abstract: 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.
