US Patent 8033348 Self-propelled child stroller

A self-propelled stroller apparatus comprising a motor, a drive train, a braking mechanism, and a set of hand controls, is herein disclosed. Two (2) rear wheels of the stroller are driven by a battery-powered motor utilizing a chain-driven drive train. The motor is controlled by a handlebar-mounted control lever, which when pushed motivates the stroller in a forward direction. During times when the motor and drive train are deactivated, the stroller may be pushed in a normal manner. The apparatus is additionally provided with an emergency braking system to stop or securely park the stroller. The battery is recharged by a normal household outlet and an electrical cord when the stroller is not in use.
