ABSTRACT:
A sport vehicle comprising a vehicle frame having a step on its upper surface and an upstanding handle rod at its front end. At the lower surface of the front of the frame a front wheel axle is mounted having a pair of front wheels at its ends, the middle portion of the axle being rotatably supported through a steering shaft having a negative caster angle, the vehicle frame and the front wheel axle being interconnected through a resilient member. A single rear wheel is mounted on the vehicle frame at the lower surface of the rear portion thereof. One of the three wheels can be a driving vehicle wheel in which case a pedal lever is swingably mounted on the frame for upwards and downwards movement to drive a longitudinally extending flexible member for reciprocation in forwardly and rearwardly direction. A sprocket or the like is in engagement with the flexible member and is drivingly connected to the vehicle drive wheel through a free wheel clutch so that the vehicle drive wheel is driven only in regular direction of rotation of the sprocket and the vehicle body frame, and the connecting rod is so constructed that the same may serve also as stopper member for limiting the upward and downward movements of the pedal lever.
