Roc Motorcycles

A Brief History of the Marque

Financed by the acclaimed author Arthur Conan Doyle, Roc motorcycles were built in Guildford and later Birmingham to the design of A.W. Wall. The machines used both Precision and Roc engines of 2 to 6 hp, mostly V twins. Wall's designs included three wheelers and bicycle engines. Production ceased soon after the onset of the Great War.

There is evidence to suggest that around 1908 the ROC was built at the Rex factory in Birmingham. See Rex and ROC
