  • Publication number: 20230013264
    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.

  • Publication number: 20220388603
    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.

  • Publication number: 20220388601
    Abstract: A method for controlling electronic shifting of a bicycle includes identifying, by a processor, sensor data. The sensor data identifies a state of the bicycle. The processor determines a rider engagement status based on the identified sensor data. The processor determines a target cadence based on the determined rider engagement status. The processor determines a cadence band based on the determined target cadence. The electronic shifting of the bicycle is controlled based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of the bicycle for electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.

  • Publication number: 20220388602
    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.
