The first L.E.T. (life enhancement transport), the Go-Kid Quadcoaster is a Four Wheel Fitness Flyer. Invented by Allen Humphrey, it is a safe, stable, exhilarating Push Coasting Vehicle. It's readily accepted in school PE, including special needs and vision impaired. With a Go-Kid, the rider stands on the rear-riding platform and pushes to the rear with either foot. The resulting exercise builds large muscle strength, trunk strength, static strength, cardiovascular strength and pulmonary strength, as well as hand-eye coordination. With caliper brakes, optional lights and other optional bells and whistles, this is a riding toy like no other.
