Defy-All
Defy-All were motorcycles produced from 1921 to 1923, to a design by a Mr. Craddock, at Stalybridge, Cheshire.
The first engine used in the design was a 269cc two-stroke Villiers Mk IV, with two-speed Sturmey-Archer gearbox and chain-cum-belt transmission. This was followed by Blackburne 348cc and 549cc sv-engined models. The machine had leaf spring front forks and triangulated rear fork suspension. Despite its name, little came of it and the firm failed to survive.
