PDC motorcycles were sold by the Imperial Motor Co of Brixton Hill, London, from 1903 to 1905.
The firm offered a range of solos plus a forecar attachment. Engine sizes were 2hp, 2½ hp, 2¾ hp and 3hp. The front brake was an external-contracting band. In all other respects it was a primitive that was typical of the era, and its production life was limited.
27. Imperial Motor Co., Brixton Hill, are showing three motor-bicycles all fitted with 2 h.p. motors; the motor is fitted in a vertical position in a loop of the frame. A spray carburetter and extra large silencer are distinctive features. There is a single band brake on the rear wheel, and this looks powerful enough for any emergency. The New Palmer motor-bicycle tyre is fitted to this machine: this tyre has an extraordinary thickness of rubber on the tread, and looks particularly strong. A sight feed lubricator is fixed on the diagonal. A special line in ignition accumulators is also shown, as well as McCurd's bicycle jack. A machine ready for the attachment of the motor set is worthy of inspection.
