A power control apparatus for a bicycle that uses a first power supply and a second power supply to provide electrical power includes a voltage sensor for sensing a voltage from the first power supply. A control unit is coupled to the voltage sensor and is coupled for receiving power from the first power supply and the second power supply. The control unit outputs power from the second power supply when the voltage sensed by the voltage sensor is below a selected value, and the control unit outputs power from the first power supply when the voltage sensed by the voltage sensor is above the selected value.
