1902 Reilly designed a 3-speed hub gear. He had parted company with the manufacturer of 'The Hub' (Hub Two-Speed Gear Co) but had signed away to them the intellectual rights to his future gear designs.
To circumvent this problem, the patents for Reilly's 3-speed were obtained in the name of his colleague, James Archer.
Henry Sturmey had also invented a 3-speed hub. In 1903 Frank Bowden, head of the Raleigh Cycle Co, formed the Three-Speed Gear Syndicate, having obtained the rights to both the Reilly/Archer and Sturmey 3-speeds. Reilly's hub went into production as the first Sturmey-Archer 3-speed.
