A system for a bicycle includes a plurality of controller devices. A type of controller device is the same for two or more controller devices of the plurality of controller devices. The system includes a pairing coordinator device configured to receive a respective device type identification from each controller device, and identify the type of controller device for the two or more controller devices based on the received device type identifications for the two or more controller devices. Based on the identification of the type of controller device, the pairing coordinator device is configured to update the device type identifications for the two or more controller devices, respectively, such that the updated device type identifications are different than each other. The pairing coordinator device is configured to pair only controller devices of the plurality of controller devices having different respective device type identifications with the pairing coordinator device.

A coordinator device for a bicycle includes a processor configured to receive a signal generated in response to user input at an input element from a controller device. The signal includes data identifying a device type and data identifying the input element. The coordinator device includes a memory configured to store the data identifying the device type and the data identifying the input element. The processor is configured to generate a notification based on the received signal, transmit the generated notification to the mobile device, and in response to the transmission of the generated notification, receive a request for data related to the received signal from the mobile device. The processor is further configured, in response to the request, to transmit the stored data to the mobile device, such that an association of the controller device with the representation of the controller device is identifiable within the GUI at the mobile device.

A control device includes an electronic controller configured to automatically control a transmission device of a human-powered vehicle in accordance with a shifting condition. The electronic controller is configured to set the shifting condition based on first reference information including information related to change in transmission ratio that is shifted by the transmission device.

To provide a shifting control device and an electric shifting system allowing a user to comfortably ride a human-powered vehicle, a shifting control device comprising a controller configured to control a shifting device in accordance with a first operation performed on an operating device for braking a rotary body of a human-powered vehicle.

An electrically powered bicycle equipment has an attachment/detachment seat for an electric power supply unit, and a latch assembly for holding the electric power supply unit in the seated state includes a slider having a head and a back. Either the electric power supply unit or the equipment has a sliding seat for the slider, the other one has a retaining seat for the head. The sliding seat accommodates the back of the slider, which has a peripheral groove and a ring gasket housed in the peripheral groove. The groove has two aligned sections and a deeper intermediate section between them. When the slider is in the fully advanced position, a gasket portion bridges the intermediate section between the two aligned sections, and when the slider moves back, the gasket portion can curve towards the bottom of the intermediate section of the peripheral groove.

A bicycle electronic equipment configured to be attached to a location of the bicycle includes a data processing system, a multicolour light source, and a switch. The switch includes a push-button and a two-state electric circuit. The data processing system is configured to: (a) make the light source emit cyclically repeating N coloured light emitting patterns, with N>=3, wherein coloured light emitting patterns immediately consecutive in the cyclical repetition differ in color and/or type of emitting pattern; (b) monitor the state of the switch during execution of step (a); and (c) perform a different action among N different actions according to which of the N coloured light emitting patterns the source is emitting upon the state switching of the switch.

An electrically powered bicycle equipment has a component with a seat for removable attachment of an electric power supply unit, and a clamping device of the electric power supply unit to the component. The clamping device is pivotally supported by the component or the electric power supply unit about a first geometric axis stationary with respect thereto, and about a second geometric axis, which is parallel to, pivotal about, and not translatable with respect to, the first geometric axis. Either the component or the electric power supply unit has a retainer member and the clamping device has a retainable member that is urged against the retainer member. The rotation of the clamping device in a first direction about the first axis and in a second direction opposed to the first direction about the second axis allows the retainable member to be brought beyond the retainer member during clamping and unclamping.
