Imperial were motorcycles produced between 1901 and 1903, by Norman Downs in Birmingham. It was the name he used when he founded the company and before he added New in front of it.
1901 Having already been established in the bicycle trade, Downs entered the powered market at the Stanley Show. A model was exhibited that had a 3½ hp engine mounted above the front wheel which it drove by belt. Only one machine was sold and all the others were used by staff.
