Abstract: A front wheel of a scooter is pivotally mounted to a frame and includes an upwardly extending shaft supporting a handlebar for steering the scooter. A footpad or peg or pedal, mounted on a spring returned lever, is interconnected with the rear wheel through a gear mechanism supported by the frame. By pumping the footpad, rotation of the rear wheel and forward motion of the scooter occurs. The gear mechanism includes a first gear or sprocket mounted for rotation about the arms of rotation of the rear wheel. A further sprocket coaxially mounted is linked via a drive-chain to a sprocket on an offset shaft. A further sprocket on the offset shaft drives a final, drive sprocket via a further chain. And the final sprocket drives the rear wheel through a one way clutch. Depression of the footpad, peg or pedal moves a rack-like bar longitudinally. The bar is in engagement with and drives the first gear or sprocket. The bar may carry drive-chain cross-members or pins that engage the teeth of the first sprocket.
