Abstract
A personal transportation device comprises a riding platform supported by one or more wheels, a steering mechanism at least partially embedded in the riding platform and a drive wheel assembly. A first wheel may be steerable while a second wheel is a slave wheel. The steering mechanism may be foot-operated. The drive wheel may be hand-propelled and non-steerable. The drive wheel is operatively connected to a drive sprocket and chain and is coupled to the riding platform by a platform frame. The personal transportation device may comprise one or more track arm assemblies coupled to the drive wheel assembly such that movement of the track arm assemblies operates the drive wheel assembly and rotates a drive wheel to propel the vehicle.
