Abstract: A control device of a bicycle includes an actuator and a first controller. The first controller is configured to generate and transmit, from the first controller to a second controller of the bicycle, messages for a predetermined time period at a first transmission rate in response to activation of the actuator. The first controller is further configured to, after the predetermined period of time, generate and transmit, from the first controller to the second controller, one or more messages at a second transmission rate until the actuator is deactivated. The first transmission rate is greater than the second transmission rate, and each of the messages includes data identifying the activation of the actuator.

Abstract: An electrically actuated component of a bicycle includes a first controller configured to receive a data stream from a second controller. The data stream includes one or more packets received by the first controller. For each of the one or more packets received by the first controller, the first controller is configured to identify a number of the one or more packets of the data stream received by the first controller, and compare the identified number of packets to a predetermined threshold number of packets. After all packets of the one or more packets of the data stream have been received by the first controller, the first controller is configured to initiate, based on the respective comparison, an action of the electrically actuated component or another electrically actuated component of the bicycle when the identified number of packets is less than the predetermined threshold number of packets.

Abstract: A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a gear shift command. The processor adjusts a cadence band based on the identified gear shift command. The cadence band includes an upper cadence limit and a lower cadence limit. Adjusting the cadence band includes increasing the upper cadence limit, decreasing the lower cadence limit, or increasing the upper cadence limit and decreasing the lower cadence limit. The electronic shifting of the bicycle is controlled based on the adjusted cadence band.

Abstract: A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a torque at a crank arm of the bicycle. The processor compares the identified torque or a parameter based on the identified torque to a predetermined band. The predetermined band has an upper limit and a lower limit. The processor determines a target cadence based on the comparison. The processor determines a cadence band based on the determined target cadence. The method also includes controlling the electronic shifting of the bicycle based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of a derailleur of the bicycle for the electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.

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.

The electronic control device may also be dimensioned to have a compact and/or concealed appearance aided by a low profile relative to the bicycle mounting surface selected for the control device.

Abstract: In an adjustment mode for a derailleur of a bicycle, acceleration values from an accelerometer of the derailleur are sampled as the derailleur moves through sprockets of a rear sprocket assembly. Acceleration signal powers are identified based on the sampled acceleration values, and potential rasping positions are identified based on thresholding of the acceleration signal powers. The identified potential rasping positions are compared to expected rasping positions, and adjustment for the derailleur is set based on a minimum error between the identified potential rasping positions and the expected rasping positions.
