Balancing wheels for motorcycle - has two stabilising wheels at rear, lowered to ground at low speeds

摘要

The motor driven bicycle has smaller dia. stabilising wheels mounted at each side of the rear wheel. These can be lifted from contact with the ground at higher speeds and lowered at low speeds. The seat is mounted at very low level on a frame between the front and rear wheels, for a low centre of gravity. The stabilising wheels are mounted on forks connected to a swinging lever with springs incorporated to improve the suspension. The bottom of the lever is connected by a cable to a control arm at the front for raising and lowering the stabilising wheels.
