Cyril George Pullin (1893-1965) was a British, inventor, engineer and motorcycle race driver born in Hammersmith.
In the 1920's he developed the Ascot car and had various helicopter engine patents.
In 1925 he developed the Powerwheel, a single cylinder rotary engine in the hub of a motorcycle wheel, including clutch and drum brakes. His sister was married to Stephen Leslie Bailey, a then prominent engineer at Douglas Motors, and many of his patents were filed under the name of that company.
