PCT No. PCT/AU93/00544 Sec. 371 Date Jul. 15, 1996 Sec. 102(e) Date Jul. 15, 1996 PCT Filed Oct. 22, 1993 PCT Pub. No. WO94/09872 PCT Pub. Date May 11, 1994A wheeled vehicle (200) for carrying a person comprising a frame (218, 220, 222, 250) rotatably supporting two substantially in-line wheels (204, 206), and foot support means (254, 256) for, in use, supporting the feet of a user. The wheels are ring-shaped, and the foot support means are in the form of spaced platform structures coupled to the frame and which extend axially through respective said wheels. In order to allow the foot platforms to extend through the central portion of the ring shaped wheels whilst allowing the wheels to rotate, the wheels are rotatably supported on the frame by a plurality of rollers (210) mounted on the frame and arranged around the wheels to bear on circumferential surfaces thereof (208). A motor (236) may also be included to drive one of the wheels under control of the user who is able to operate a hand held throttle control (239). |
