Example pedal detection devices for bicycles are described herein. An example a pedal detection device includes an electronics module to be disposed in a spindle of a crankset of the bicycle. The electronics module includes a sensor to detect angular velocity and/or position of the spindle, a driver, and an expander wedge movably coupled to the electronics module via the driver. Axial movement of the expander wedge relative to the electronics module causes the expander wedge to expand radially.

Pedal detection devices for bicycles

A wireless control system for a bicycle, comprising a first shift control unit for a component of a bicycle, the first control unit comprising a radio configured to receive control signals, wirelessly transmitted by a second control unit of the bicycle; the radio operable to receive the control signals only when the radio is operating in a listen mode; and a processor configured to: activate the listen mode of the radio for a first length of time; detect, with the radio, a noise level during the first length of time; and extend the activation of the listen mode for a first extended time period when the noise level achieves a noise level threshold.
