This University of Bristol aeronautics graduate fitted the Puch with high pressure carbon fibre air cylinders used by fire fighters as breathing apparatus in burning buildings.
The cylinders power two rotary air engines which in turn drive the chain to the rear wheel.
Unlike electric scooters, it takes just seconds to recharge from larger air tanks filled by a diving compressor.
With a top speed of 18mph and a range of just seven miles between air top-ups, Stansfield admits it’s never going to be good for trans-continental touring. But hesaid: “You could definitely run a fleet of delivery bikes on it.”
