1920 - 1924
Claude Grahame-White was a pioneer aviator who set up a flying school at Pau in France in 1910. Three years later he started a factory to make biplanes at Hendon airfield in Britain. After the war he felt the need to diversify and the products of his company were quoted as aeroplanes, cyclecars, coachwork, bedroom suites and office furniture. He made 2 types of cyclecars, the G-W Buckboard and the WonderCar/7hp. The former was on the lines of the Briggs & Stratton, with no suspension apart from the flexing of the frame, though it had a little more bodywork and normal drive to the rear wheels. It was powered by a 3hp single-cylinder air-cooled engine with 2-speed gearbox and chain drive, and cost 85 guineas (£99.75), The WonderCat and 7hp were similar in appearance but the former was powered by a 348cc 3.5hp Precision engine and shared the Buckboard's 2-speed gearbox, while the latter had a 685cc 7hp Coventry-Victor flat-twin and friction transmission.
Several hundred of these three models were made and there was also a proper light car powered by a 1094cc 4-cylinder Dorman engine and shaft frive. Only three of these were made.
