SPRING WHEEL GIVES CYCLISTS A SMOOTH RIDE

Details are given of a puncture-proof bicycle with a new type of wheel. Unlike conventional wheels, which are rigid, the suspension wheel flexes according to the load on it. The bicycle can have solid rubber tyres. The wheel has 2 sets of spokes, one conventional, the other flexible. The conventional set is a simple row of thin wires which connect the centre of the wheel to the rim ensuring that the rim does not distort. The second set of spokes is a series of parallelograms, linking the axle to the rim. The parallelograms have rigid ends but sprung sides. They deform under load, while retaining their geometric shape, and put a "spring" in the wheel by moving the hub off centre. The bicycle has no further damping. The suspension wheel is the invention of John Moore, a retired engineer from Norwich. (TRRL)
