Silver Queen Cycle Co

Royal Ajax were motorcycles produced by the Silver Queen Cycle Co of Gray's Inn Road, London, between 1904 and 1906. The marque is also listed as being produced by British Cycle Manufacturing Co.

The machine was a typical primitive fitted with a 2½ hp engine, upright in a cradle within the frame. It had belt drive and rigid forks and was probably an Alldays and Onions model with a different tank transfer.

It was only listed until 1906 and nothing more was heard of it.
