Think of a cross between a motorized skateboard and a scooter and you have the 20 MPH Motorized Wheelrider ($500). You place your feet inside the hubless tires and steer with a side to side motion directed at the front wheels. The Wheelrider has a 2-horsepower enginine which is controlled by a handheld throttle. It requires an oil and gas mixture and can go for about an hour between refills.
