Sir John Carden was a prolific designer who went on to work on tanks but started his career with cyclecars. His first design was a wooden bodied single seater powered by a 481 cc single cylinder JAP engine driving the back axle by belt. There was no gearbox. At first he had built the cars at his home but demand was sufficient to warrant moving to larger premises in Teddington in February 1914. thumb|right|alt=Carden cyclecar|Carden cyclecar
