Glencairn were motorcycles produced in 1903.
There is little information on this make and few are thought to have been built. They were assembled from bought-in parts and probably based on a standard heavy-duty gents' bicycle. The engine would have been extremely basic and either imported or bought from a firm in the Midlands. It was reputedly built for export, but there is no indication as to whether this was for the European market or elsewhere.
