Birch were motorcycles produced from 1902 to 1904.
The designer, J. J. Birch, was one of the partners of Perks and Birch who produced the motor wheel that would be used by Singer at a later date. He was also known to have produced a very basic motorcycle, which had the crankcase and bottom bracket as part of the main frame. The engines were manufactured in several sizes: 2hp, 2.5hp and 3.5hp. The design was also built under licence, by Bradbury.
