Abstract
This invention is a user-propelled riding toy. A platform on which a user stands is supported by at least two wheels; and a geartrain mounts to the wheels. The geartrain is adapted to receive a downward force from the pedals, and translate a portion of the downward force into a rotational force on the wheels. The geartrain also provides an upward return force acting on the pedal. The platform is propelled forward direction by the rotational force on the wheels. When one pedal is pressed down, the other pedal will be raised simultaneously.
