The first model produced was the 1920 cyclecar equipped with a 10 hp. air-cooled engine mated to a leather clutch and two-speed gearbox. Design and development had taken approximately 12 months and a prototype completed a 2,000 mile test. The shapely "radiator" was a combined three-gallon petrol tank and three-quart oil tank.
