Abstract: A wireless control system for a bicycle, comprising a first shift control unit for a component of a bicycle, the first control unit comprising a radio configured to receive control signals, wirelessly transmitted by a second control unit of the bicycle; the radio operable to receive the control signals only when the radio is operating in a listen mode; and a processor configured to: activate the listen mode of the radio for a first length of time; detect, with the radio, a noise level during the first length of time; and extend the activation of the listen mode for a first extended time period when the noise level achieves a noise level threshold.

Abstract: Bicycle component motion control begins when a motorized bicycle component is commanded to shift or actuate. The bicycle component motion control compares parameters of a component of the bicycle to be moved, to predetermined thresholds to provide safe shifting or actuation. The shift or actuation starts only when the battery voltage and the battery temperature are within predetermined acceptable ranges, respectively. Once the shift or actuation has started, the shift or actuation is aborted if the battery voltage remains below a predetermined low voltage threshold for a predetermined amount of time. If the shift or actuation is aborted when the component is in a position, in which the bicycle may not operate at a particular level or is inoperable, the shift or actuation command is modified to move the component to a previous position or an intermediate position.

Abstract: A bicycle system includes controller devices. Each controller device includes at least one respective input element configured to receive input from a user. The system includes operation-enacting devices. Each operation-enacting device is configured to enact at least one respective operation on the bicycle. The system includes a network coordinator device configured to (i) establish a wireless network for communications between the network coordinator device, the controller devices, and the operation-enacting devices, and (ii) reset the controller devices and operation-enacting device before pairing the controller devices and operation-enacting devices to the wireless network.

The system includes operation-enacting devices. Each operation-enacting device is configured to enact at least one respective operation on the bicycle. The system includes a network coordinator device configured to (i) establish a wireless network for communications between the network coordinator device, the controller devices, and the operation-enacting devices, and (ii) transmit to the operation-enacting devices, via the wireless network, a roster identifying the controller devices and the operation-enacting devices paired to the wireless network. The controller devices are configured to transmit to the operation-enacting devices, via the wireless network, signals indicating input received by the input elements of the controller devices. The operation-enacting devices are configured to determine, based on the roster, how to enact the operations responsive to the signals received from the controller devices.

Abstract: A bicycle control system may be provided to control a first gear changer with a control unit and a second gear changer with the first gear changer. The control unit may control both first and second gear changers. The system includes a predetermined shift path and may transition in and out of the predetermined shift path responsive to various controls. Shifts out of the predetermined shift path may be recovery shifts where both first and second gear changers are controlled.
