Abstract
An electrically powered cycle has a frame, an axle, a drive wheel, an electric motor, a motor controller, an electric power supply, a power supply charger, and a swing arm pivotally mounts the electric power supply and electric motor on the cycle frame. The drive wheel is rotatably supported on the axle, which, in turn, is supported in the swing arm adjacent the rear end of the cycle. This end of the swing arm is coupled to the shock absorbers which connect the frame to the axle so that the drive wheel moves relative to the frame. The other end of the swing arm is pivotally mounted on the frame. The electric power supply and the electric motor are supported on the swing arm intermediate the ends thereof.
