Abstract: A bicycle control device that easily maintains the ratio of the assist force generated by a motor to the human drive force input to a bicycle at a predetermined ratio includes an electronic controller that controls a transmission, which is configured to change the transmission ratio of the bicycle, and the motor, which assists propulsion of the bicycle. The electronic controller is configured to control the motor so that the ratio of the assist force generated by the motor to the human drive force inputted to the bicycle becomes equal to the predetermined ratio. The electronic controller is configured to control the transmission in correspondence with at least one of the output torque of the motor and the human drive force to maintain the predetermined ratio.

Abstract: A bicycle control device includes an electronic controller that controls a motor, which assists propulsion of a bicycle. The electronic controller is configured to decrease an output of the motor to less than or equal to a limit value upon determining a shifting device is performing a shifting action to change a transmission ratio of the bicycle. The electronic controller is further configured to change at least one of the limit value of the output of the motor and a time in which the output of the motor is decreased upon determining the shifting device is performing the shifting action in accordance with at least one of an actuation state of the shifting device in the shifting action and a parameter of the bicycle that is changed by the shifting action performed by the shifting device.

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. 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.

Abstract: A bicycle controller controls a motor in accordance with the riding environment of a bicycle. The bicycle controller includes an electronic control unit that is configured to control a motor that assists in propulsion of a bicycle in accordance with a manual driving force. The electronic control unit is further configured to set a response speed of the motor with respect to a change in the manual driving force input to the bicycle for a case within a predetermined period from a time at which the bicycle starts to travel to be different from the response speed for a case in which the predetermined period has elapsed.

Abstract: A bicycle seatpost assembly comprises an electric actuator and a seatpost controller. The electric actuator is to change a state of the bicycle seatpost assembly between a lock state where a total length of the bicycle seatpost assembly is invariable, and an adjustable state where the total length of the bicycle seatpost assembly is variable. The seatpost controller is configured to control the electric actuator to maintain the adjustable state during an adjustment period selectable from a plurality of predetermined adjustment periods.

Abstract: A bicycle seatpost system comprises an electric actuator, a remote controller, and a seatpost controller. The electric actuator is to change a state of a bicycle seatpost assembly between a lock state where a total length of the bicycle seatpost assembly is invariable, and an adjustable state where the total length of the bicycle seatpost assembly is variable. The remote controller is configured to transmit a first control signal and a second control signal different from the first control signal. The seatpost controller is configured to control the electric actuator to change the state of the bicycle seatpost assembly to the adjustable state based on one of the first control signal and the second control signal.
