 As well as the first use of hydraulic brakes on a motorcycle, Pullin also designed a telescopic centre stand and an adjustable windshield with a windscreen wiper and rear-view mirror, as well as a fully enclosed chain and interchangeable wheels.The Ascot-Pullin name was revived in 1951 by the Hercules Cycle and Motor Company, a
division of Tube Investments, who commissioned Pullin's new invention, the "Powerwheel", a , , single-cylinder rotary engine.The prototypes were scrapped after the company decided not to proceed with production, but a sectionalised example survived together with most of the drawings, and an industrialised version was developed for the Ministry of Supply.
