Amusement vehicle

A vehicle comprising:

• a pair of coaxial wheels having inwardly facing annular surfaces,
• a frame generally within the radial confines of said wheels extending axially between said wheels,
• an inwardly extending annular support rim on the annular surface of each of said wheels, said support rims each having an inner surface and a side surface,
• a plurality of rollers means rotatable on respective horizontal axes on said frame and distributed circumferentially in the planes of and supportingly engaging the inner surfaces of said support rims so as to rotatably support said frame on said wheels,
• a seat in said frame adapted for seating an occupant,
• the center of gravity of said frame including any occupants seated therein being substantially lower than the common axis of said wheels,
• a chain rigidly secured circumferentially to each of said wheels within the radial confines of said wheels and concentric with the common axis of said wheels, each of said chains being axially displaced from the support rim for its respective said wheel,
• a rotatable sprocket engaged with each said chain, occupant actuated means drivingly connected to said sprockets, and
• a plurality of first guide rollers connected to said frame for rotation about respective axes which intersect the common axis of said wheels, said rollers engaging the side surfaces of respective said support rims.
