Viaduct Motor Company of Broadheath, Altrincham

1920 Ayres-Hayman was a motorcycle designed by Harold Hayman. It had a 689cc flat-twin sv Coventry-Victor in-line engine, duplex tube-frame, leaf-spring rear suspension and the maker's own gearbox. All the other major components were bought in. It was intended for sidecar use, but as Harold Hayman retired in March of that year the expectations came to nothing.

Ayers-Layland was a motorcycle produced in 1920. This machine was a successor to the Ayres-Hayman and also produced by the Viaduct Motor Co, of Cheshire, who now had W. H. Layland as an advisor. In June of that year a complete machine with a 689cc sv flat-twin engine and three-speed Sturmey-Archer gearbox was shown. It is not thought to have progressed beyond prototype stage.
