Abstract: A bicycle including a frame that has a head tube, and a frame member that is elongated along a longitudinal axis. The bicycle also includes a receiver that is disposed in the frame member, and a battery pack that is coupled to the frame member and detachably connected to the receiver. The receiver has a tapered socket and a power connector encircled by the tapered socket. The battery pack has a tapered end cap that is insertable into the tapered socket along the longitudinal axis. The tapered end cap includes a battery connector disposed on an end of the battery pack. The tapered end cap is at least partially nested within the tapered socket along the longitudinal axis upon connection between the receiver and the battery pack, and the battery connector is electrically connected to the power connector upon nesting the tapered end cap in the tapered socket.

Abstract: A method of preventing rotation of an axle of a bicycle including a dropout having a recess. The method includes coupling a motor to the axle, attaching a torque element to an end of the axle, engaging the torque element into the recess in the dropout, and inhibiting rotation of the axle relative to the dropout in response to torque from the motor.

Abstract: A bicycle including a wheel that has an axle with a first end and a second end, a motor coupled to the axle, and a frame supported by the wheel. The frame includes a first dropout and a second dropout, and the first dropout defines a recess. The bicycle also includes a torque element that is secured to the first end of the axle and that is shaped to fit within the recess of the first dropout to inhibit rotation of the axle relative to the frame in response to torque from the motor.

Abstract: A bicycle including a frame, a bottom bracket coupled to the frame and adapted to support a crankset, and a battery pack supported by the frame. The battery pack has a powered end cap with a tapered protrusion and a battery connector on an end of the tapered protrusion. The bicycle also includes a receiver supported by the frame and including a tapered socket in which the tapered protrusion is positioned. The tapered socket includes a power connector detachably coupled to the battery connector.

Abstract: A bicycle including a frame that has an elongated hollow frame member, a fork rotationally coupled to the frame, a wheel rotationally coupled to the fork, and a handlebar coupled to the fork for steering the wheel. The frame has an interior surface that defines a longitudinal groove with a groove width. The bicycle also includes a cable that is positioned in the longitudinal groove and that has a cable width less than the groove width.

Abstract: 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.
