Abstract
A bicycle shifting control apparatus controls an electrical power supplied from a power supply to first and second gear shifting devices that are operated by first and second gear shift operating devices, respectively. The bicycle shifting control apparatus includes a first power supply sensor and a controller. The first power supply sensor detects a power level of the power supply. The controller receives a power level signal from the first power supply sensor. The controller performs a stopping operation of the first gear shifting device in response to the first power supply sensor detecting the power level of the power supply being below a first prescribed power level, but the controller transmits a second gear shift signal from the second gear shift operating device to the second gear shifting device to perform a second shifting operation of the second gear shifting device.
