Sturmey-Archer is a manufacturing company from Nottingham, England. They primarily produced bicycle hub gears but have also produced motorcycle components including hubs, gearboxes and complete engines.

The company was founded in 1902 by Henry Sturmey and James Archer under the guidance of Frank Bowden (from whose name the term 'Bowden cable' originates) the primary owner of the Raleigh bicycle company. They originally produced hubs for three-speed bicycles designed by Raleigh, but in 1939 a four speed model was developed. This led to the development of temperamental 5 speed models, and by 1994, 7 speed hubs were introduced. The Sturmey-Archer name was also credited with the 49cc two-stroke engine fitted to early Raleigh mopeds, although this was actually a reworking of Vincenti Piatti's "Trojan Mini-Motor" and built by BSA's motorcycle operation.

In 2000, Sturmey-Archer was sold to Sun Race Sturmey-Archer Inc. and operations were moved to Taiwan.

1928 - Victoria employed an S-A engine which was most likely built at their factory in Germany.

N.B. The Sturmey-Archer three-speed epicyclic gear was not invented by Sturmey or Archer, but by one William Reilly. "To save Sturmey’s blushes, and to create a more marketable product (Sturmey was one of the most famous cycle engineers of his day), Raleigh relegated Reilly to the sidelines and instead promoted Sturmey and Archer, neither of whom had anything to do with the hub gear their names became attached to." ~
