Bicycle wireless control system
A bicycle wireless control system is basically provided with a first bicycle electric component and a second bicycle electric component. The first bicycle electric component includes at least one operating member and a first wireless communication unit that wirelessly transmits a control signal in response to an operation of the at least one operating member. The second bicycle electric component includes a second wireless communication unit that is configured to wirelessly receive the control signal from the first wireless communication unit and to wirelessly transmit an acknowledgement signal to the first wireless communication unit upon receiving the control signal from the first wireless communication unit.
1. A bicycle wireless control system comprising:
a first bicycle electric component including at least one operating member, a first controller, and a first wireless communication unit that wirelessly transmits a control signal in response to an operation of the at least one operating member; and
