<p>A toy vehicle (10) comprising a base or frame (12) and wheels (16a 16b, 26a, 26b) and a movable weight (30,32) coupled to a lever (40) which is manually operable to alter the centre of gravity. There may be two weights (30,32) one adjacent each of the rear wheels which are pivotally movable by the lever, or there may be a sliding platform (230) to which the rear wheel are coupled so that the wheel base of the toy vehicle can be adjusted, or the lever may be weighted (332) and connected to movable first and second arms (300, 302) each with a projection (314, 332) pivotally supported on the frame proximate the first and second rear wheels. Movement of the weight or weights alters the centre of gravity and this varies the performance of the moving toy vehicle. Projections either immovable (260, 262, 264) or movable (38, 39, 314, 322) with the positioning of the weight may be provided which projections contact the surface (8) on which the toy vehicle is riding to further vary the performance of the vehicle.</p> |
