  • SURFACE FEATURE TRANSFER MEDIA AND METHODS OF USE
    Publication number: 20230104963
    Abstract: Forming features in the surface of a bicycle component involves depositing a substance onto a substrate in a geometric pattern to form a transfer medium. Forming features may also involve positioning the transfer medium relative to an unformed bicycle component, and forming a negative of the geometric pattern in the bicycle component through the application of heat and/or pressure to the transfer medium and the unformed bicycle component. The transfer medium may be configured for use in the molding of carbon fiber reinforced plastic (“CFRP”) bicycle components and may include a substrate formed of a flexible material, and a geometric pattern formed of a hard material, the hard material different than the flexible material.

  • LOW POWER CONTROL FOR A CONTROL DEVICE FOR A BICYCLE
    Publication number: 20230060541
    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.

  • BICYCLE COMPONENT CONTROL
    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.
