A bicycle communication apparatus is provided that contributes to usability. The bicycle communication apparatus includes a base portion and a wireless communicator provided at the base portion. The wireless communicator is configured to transmit first information related to a motor that assists propulsion of a bicycle and second information related to a shifting device of the bicycle through wireless communication.

Bicycle communication apparatus

An electronic device comprises a wireless transmitter and an operation device. The operation device comprises a base, a brake lever, operation portions and an electronic controller. The base is to be removably attached to a handlebar. The operation portions includes first, second and third operation portions. The first operation portion is arranged on the base. The second and third operation portions are arranged adjacent to the brake lever and are disposed between the brake lever and the handlebar. At least one of the operation portions includes a lever. At least one of the operation portions includes a button. The electronic controller is configured to transmit an operation signal to the wireless transmitter upon operation of any of the operation portions to control at least one bicycle component that is any one of a shifting device, a brake device, an adjustable seatpost, a suspension and a drive unit.

Electronic device and method for controlling electronic device

A controlling device includes a storage device configured to store predetermined information about durability of a component of a man-powered vehicle, and a controller configured to control an indicator based on the predetermined information.

Controlling device, indicating system, and controlling method

An electronic device controls at least one bicycle component in correspondence with operation of an operation device. The electronic device includes a receiver, a memory, a first wireless transmitter, a memory and an electronic controller. The receiver receives operation information corresponding to the operation of the operation device. The memory stores an actuation command of the bicycle component in correspondence with the operation information. The electronic controller receives the operation information and transmits the actuation command corresponding to the received operation information from the first wireless transmitter. The memory is configured to allow the actuation command stored in correspondence with the operation information to be changed.

A bicycle shifting control apparatus comprises a transmission controller configured to control a guide actuator of a derailleur to move a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal. The transmission controller is configured to control, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, the guide actuator to temporarily decelerate the chain guide at a deceleration position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having a shift assist structure prior to completion of the shifting operation of the chain guide.
