BACKGROUND ART

Steerable scooters typically include a standing platform supported on a rollable rear support wheel and a steerable front support wheels. In many such scooters, the support wheels are simply skate wheels that have been attached to the standing platform. These types of scooters can be dangerous because even small rocks can prevent the support wheels from rolling, causing the scooter to come to an abrupt halt and, oftentimes, throwing the scooter rider from the scooter onto the ground. In addition, the small wheels make steering difficult and the scooter unstable because the center of gravity of the combination of the scooter and the rider is well above the top surfaces of the support wheels. It would be a benefit, therefore, to have a scooter that included large support wheels and a support platform positioned below the top surface of the support wheels. In addition, because scooters can be used to travel long distances, it would be a further benefit to have a scooter that included a seat that could be used by the rider if desired. To enhance the stability of the scooter, it would be a further benefit to have a scooter that included a seat having a top surface positioned two or more inches below the top surface of the support wheels.
