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, mounted on a spring returned lever, is interconnected with the rear wheel through a gear mechanism supported by the frame. By pumping the footpad or peg, rotation of the rear wheel and forward motion of the scooter occurs.

A foot pump scooter comprising in combination:
- a) a frame for supporting a steerable front wheel and a rear wheel;
- b) a gear mechanism adapted to impart rotary motion to said rear wheel;
- and
- c) a footpad adapted to be depressed by a rider to pivot a lever assembly resulting in curvilinear motion for actuating said gear mechanism.

- b) rotating an initial sprocket in response to said step of depressing;
- c) urging rotation of the rear wheel in one direction by rotating a final sprocket;
- and
- d) increasing the rate of rotation of the final sprocket relative to the initial sprocket with a gear mechanism.
A foot pump scooter comprising in combination:
- a) a frame for supporting a steerable front wheel, a rear wheel and a platform therebetween;
- b) an actuatable gear mechanism adapted to impart rotary motion to said rear wheel for urging forward motion of said scooter;
