First electric device, second electric device, and control system of human-powered vehicle

A second electric device of a human-powered vehicle, the second electric device comprising:

• a second wireless communicator configured to wirelessly communicate with a first wireless communicator of a first electric device using a communication protocol, the second wireless communicator being configured to wirelessly communicate with a third wireless communicator of a third electric device using the communication protocol;
• a user interface configured to receive a user input;
• a second electronic controller configured to control the second wireless communicator to reconnect to the first wireless communicator based on the user input in a disconnection state where the second wireless communicator is paired with the first wireless communicator and where the second wireless communicator is wirelessly disconnected from the first wireless communicator;
• and
• the second electronic controller being configured to control the second wireless communicator to restrict connecting to the third wireless communicator based on the user input in an additional disconnection state where the second wireless communicator is paired with the third wireless communicator and where the second wireless communicator is wirelessly disconnected from the third wireless communicator,
• the second electronic controller being configured to control, based on a pairing request input different from the user input, the second wireless communicator to wirelessly transmit a pairing request signal indicating a request to start pairing between the first electric device and the second electric device.
