There is provided a vehicle which includes a frame, a steerable wheel mounted on the frame and at least one further wheel mounted for free rotation on the frame. A flywheel is mounted for rotation adjacent one of the wheels. The vehicle includes means for imparting rotation to the flywheel, and a clutch plate rotatably and coaxially mounted adjacent the same wheel to which the flywheel is adjacent. Speed-reduction means allows rotation of the flywheel to rotate the clutch plate at a faster rate than the flywheel, and a frictionless clutch is provided between the clutch plate and the adjacent wheel.
