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: An electronic component for a bicycle includes a communication interface and a processor in communication with the communication interface. The processor is configured to identify a first power on time. The first power on time identifies a time at which the electronic component was powered on by a power source of the bicycle. The processor is configured to listen for one or more messages after the electronic component is powered on and receive, via the communication interface, a message of the one or more messages. The received message is from another electronic component of the bicycle and identifies a second power on time. The second power on time is for the other electronic component. The processor is configured to compare the second power on time to the first power on time and initiate, based on the comparison, pairing of the other electronic component with the electronic component.

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.

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: An electronic component for a bicycle includes a processor configured to receive first data from a first sensor configured to sense at least one sensed element disposed about a bicycle wheel as the sensed element rotates through a proximal region of the first sensor.

The processor is configured to determine a first speed based on a subset of the received first data when the sensed element is within the proximal region of the first sensor, and determine a second speed based on a subset of the received second data and the first speed when the sensed element is not within the proximal region of the first sensor.

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.
