In 1932, Les Blakeborough, the well known English dirt track motorcycle rider, has invented an entirely new back wheel for his racing machine, which consists of a series of large wooden balls mounted on the rim in place of the conventional pneumatic tire.
The inventor claimed his device made broadsiding more rapid, and also made it possible to broadside on hard surfaces.
