Vehicle, especially amusement vehicle

A vehicle comprising:

• a pair of coaxial spaced wheels having inwardly facing annular surfaces thereon, a frame within the radial confines of said wheels extending axially between the wheels, roller means rotatable on respective horizontal axes and distributed circumferentially on the frame in the plane of and supportingly engaging each said annular surface for rotatably supporting the frame on said wheels, seat means in the frame for seating at least one occupant, the center of gravity of said frame including any occupant seated therein being substantially lower than the common axis of said wheels, means carried by the frame and under the control of the vehicle occupant for driving at least one roller pertaining to each wheel for propelling the vehicle, said drive means comprising a differential connected between a source of driving force and said rollers, occupant controlled friction brake means for selectively retarding the rotation of one of said rollers so as to steer the vehicle, and means for spring biasing the driving roller for each wheel radially outwardly into firm driving engagement with the respective wheel.
