Sir John Carden was a prolific designer who went on to work on tanks but started his career with cyclecars.

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.

[2] In October 1914 The Motor Cycle[3] reported on a Carden Monocar they had on trial.

The engine was mounted behind the rear axle and drove it via chain, there being no differential.

[1] In 1916 the design and factory was sold to Ward and Avey Ltd who renamed the car the AV and continued manufacture until about 1924.
