An electric device comprises wireless communicator circuitry and electronic controller circuitry. The wireless communicator circuitry is configured to wirelessly communicate with first wireless communicator circuitry of a first electric device using a first communication protocol. The wireless communicator circuitry is configured to wirelessly communicate with second wireless communicator circuitry of a second electric device using a second communication protocol. The electronic controller circuitry is configured to control the wireless communicator circuitry to wirelessly transmit a first signal using the first communication protocol. The electronic controller circuitry is configured to execute pairing between the electric device and the first electric device based on a first response signal wirelessly transmitted from the first wireless communicator circuitry of the first electric device. The electronic controller circuitry is configured to control the wireless communicator circuitry to wirelessly transmit a second signal using the second communication protocol regardless of the first response signal.

Electric device of human-powered vehicle

A control device for a human-powered vehicle includes an electronic controller. The human-powered vehicle includes a motor that applies a propulsion force to the human-powered vehicle and a transmission that shifts a transmission ratio of the human-powered vehicle between a plurality of shift stages. The electronic controller is configured to control the motor. The electronic controller is configured to decrease an upper limit value of an output of the motor in an up-shift operation. The electronic controller is configured to decrease the upper limit value in a down-shift operation. The electronic controller is configured to control the motor so that the upper limit value in the up-shift operation performed between two predetermined ones of the shift stages that differ in the transmission ratio by one stage differs from the upper limit value in the down-shift operation performed between the two predetermined ones of the shift stages.

Control device for human-powered vehicle

A human-powered vehicle control device includes an electronic controller configured to control a motor to drive a transmission body with the motor and operate the transmission body with a derailleur to perform a shifting action that changes the transmission ratio in a case where a crank axle is stopped. The electronic controller includes a first control state in which the shifting action is performed and a second control state in which a driving force of the motor during the shifting action is reduced compared to the first control state. The electronic controller shifts the control state to the second control state in a case where a rider is riding the human-powered vehicle and the human-powered vehicle is stopped. The electronic controller shifts the control state from the second control state to the first control state in a case where a predetermined condition is satisfied.

Human-powered vehicle control device

A notification device basically including a display and a controller. The display is configured to selectively display first information related to a traveling state of a first human-powered vehicle and second information related to a positional relationship between the first human-powered vehicle and a second human-powered vehicle that is different from the first human-powered. The controller is configured to control the display to display the second information in a case where the positional relationship between the first human-powered vehicle and the second human-powered vehicle satisfies a predetermined condition.
