Abstract: 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.

Abstract: A first electric device comprises a first wireless communicator, an electric actuator, and a first electronic controller. The first electronic controller is configured to control the electric actuator to generate the actuation force based on a user input received by the second electric device in a connection state where the first wireless communicator is paired with the second wireless communicator and where the first wireless communicator is wirelessly connected to the second wireless communicator. The first electronic controller is configured to control the first wireless communicator to reconnect to the second wireless communicator based on the user input received by the second electric device in a disconnection state where the first wireless communicator is paired with the second wireless communicator and where the first wireless communicator is wirelessly disconnected from the second wireless communicator.

Abstract: 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.

Abstract: A notification device basically includes a display and a controller. The display is configured to display information related to positional relationship between a plurality of human-powered vehicles. The controller is configured to set a privilege for displaying the information related to the positional relationship on the display. The controller is further configured to display the information related to the positional relationship on the display in a case where the privilege for displaying information related to the positional relation has been set.

Abstract: 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.

Abstract: 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.
