Publication number: 20010040352Abstract: The vehicle can be used for transportation or recreation. The rider can choose to propel the vehicle by either manipulating the steering mechanism back and forth to “walk” the vehicle forward or backward across the ground or propel it with one foot upon the vehicle and one pushing off of the ground or with ski poles. The vehicle offers all of the mobility of a scooter or skateboard but with the added stability and safety of five wheels. Seated or standing riders can use the scooter. A seated rider can sit directly on the frame or on a raised seat platform. It can be adapted to employ foot manipulation to produce the back and forth “walking” propulsion. The vehicle is capable of adaptation to provide either foot or hand steering. The vehicle is capable of many incarnations including a steerable skateboard, a steerable snowboard and a steerable sidewalk ski-board.Type: ApplicationFiled: April 12, 2001Publication date: November 15, 2001Inventors: Jar-Chen Wang, Hong-Jiun Gu
