Abstract
The wheeled personal transportation device includes a frame member having opposed front and rear ends having front and rear wheels rotatably mounted thereto. An air cushion has upper and lower ends, the lower end being supported by the frame member. A foot platform is mounted on the upper end of the air cushion, the foot platform being adapted for supporting a foot of a user. A pneumatic motor is mounted on the front end of the frame member and is in communication with the front wheel for selectively driving rotation thereof. The pneumatic motor is in fluid communication with the air cushion such that compression of the air cushion by the user's foot drives the pneumatic motor to drive rotation of the front wheel. A pneumatic brake is further in communication with the rear wheel for selective braking thereof. Alternatively, the front wheel may be powered mechanically by spring-biased gears.
