A scooter having a simple harmonic drive including front and rear wheels, a frame connecting the two wheels, a steering mechanism for steering the front wheel, a platform of sufficient size to allow a rider to stand thereon, the platform being mounted to said frame near its forward end and being spring biased at its rear end to be urged upwardly, a driving clutch connected to the rear wheel and to the rear of said platform so that shifting of the center of gravity of the rider fore and aft creates an up-and-down simple harmonic driving movement of the rear of the platform and the driving movement of the scooter. In one form, a spring is mounted on the frame and engages the rear of the platform to urge it upwardly. In modified form, the platform is cantilevered from a bracket secured to the front portion of the frame and is a spring itself so that no separate spring is used to provide the simple harmonic drive.
