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.

Embodiments of the invention provide a customizable bicycle saddle for a bicycle. The bicycle saddle has been designed to allow it to be adjusted to match the ischial tuberosities of each rider's pelvis in order to minimize the pressure placed on other portions of the rider's body while seated on the bicycle. The bicycle saddle comprises a first seating portion that has been configured to allow a rider to sit on the bicycle, a second seating portion that has been configured to allow the rider to sit on the bicycle. The bicycle saddle also includes a first adjustment means configured to allow the first seating portion to be moved closer to the second seating portion, and a second adjustment means configured to allow the saddle to be moved closer to a forward portion on the bicycle.
