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.
