The car was designed by magazine editor F.J. Camm and G.A. Broomfield and powered by an air-cooled Johnson 192 cc two-stroke flat twin engine, driving the single rear wheel by a chain. The engine was more commonly found in outboard motors and mopeds. There was no reverse, but a free wheel mechanism was fitted to help manoeuvring the machine by hand.
The Cambro was advertised as the cheapest car in the world, costing only 79 guineas (GBP83). The number made is not known.
