The Cadogan Garage produced Wilkinson-Antoine motorcycles from 1903 to 1905 in Chelsea, London.
These machines were exhibited at the 1903 Crystal Palace show and built using Belgian Antoine engines of 2¼ hp or 2¾ hp fitted into a loop frame. They had flat-belt drive to the rear wheel, the rear pulley also acted as a brake drum.
