Peter Hay

From Graces Guide

MPH were motorcycles produced from 1921 to 1922, by Peter Hay of Tyseley, Birmingham.

1921 They entered the market in March to offer a conventional appearing lightweight with a 269cc Wall two-stroke engine. It had a choice of single-speed or two-speed transmission; the latter with a Roc gearbox.

1922 they now used the Broler 349cc two-stroke motor, which gave better performance. Transmission had changed to two or three speed, through Albion gearboxes. Belt final-drive remained. It was their last year.
