<p>A rider-propelled wheeled vehicle comprises a support surface (2) for supporting a user's feet, which defines a longitudinal axis (L), a pair of front wheels (3, 3') and a pair of rear wheels (4, 4') associated with the support surface, means (5) for rotatably connecting the rear wheels (4, 4') to the support surface (2), and adapted to allow them to oscillate about a first oscillation axis inclined with respect to the support surface (2). The rear wheels (4, 4') have respective first pivot axes (O-i, Omicron&Iacgr;) independent of and transversally offset from each other for at least partial transfer of the propulsion exerted by the user on said support surface (2) to such wheels and for generation of a reaction substantially parallel to the plane to thereby promote a forward motion of the structure.</p> |
