A bicycle including a frame, an electrical circuit including a power source, and an electrical connector. The electrical connector includes a first port defined by a first terminal that has a first configuration, and a second port defined by a second terminal that has a second configuration complementary to the first configuration. The electrical connector further includes a third port that is distinct from the first and second ports, a plurality of passthrough conductors extending from the first port to the second port to connect the electrical connector to the electrical circuit, and at least one lateral conductor providing an electrical connection from the first port to the third port.
