An adjustable size three wheeled bike for young children. Propulsion and steering is done with the feet using a cable and ratchet system. The concept is similar to rowing a boat with a sliding seat where both legs are pushed forward to drive the rear wheel and one leg is pulled back to turn. 

The front axle is attached to the back wheel with a cable. A spring loaded ratchet mechanism coils the cable up when the legs are bent, and drives the back wheel as the legs are extended, propelling the vehicle forward.
