Arthur Hagg

Hagg Tandem were motorcycles produced from 1920 to 1922 by Arthur Hagg of Park Street village, near St Albans, Hertfordshire.

  • 1920 The Hagg Tandem was first introduced.
  • 1921 The machine was exhibited at the Olympia Show. It offered more than normal for two people as it was enclosed - from the downtube to enclose the rear mudguard and from the footboards up to the fuel tank, with legshields at the front. It was fitted with a 349cc Precision two-stroke engine, which drove a two-speed Burman gearbox by chain with belt final-drive. It had a long hand-lever starter, of the type to be used by Velocette some thirty years later. The rider was provided with a Lycett pan-saddle, while the passenger had a bucket seat. Brampton Biflex forks at the front and laminated lear-spring suspension at the rear, added to the all-round comfort. There was also the option of a 250cc Union two-stroke engine, and as a whole, the machine was quite advanced for its time.
  • 1922 Unfortunately, sales had not been good, so Arthur Hagg tried fitting the 349cc Barr and Stroud sleeve-valve engine. This was to give more power and less noise, but it did little to improve matters.
  • Note: For 1923 and 1924 the same engine was fitted to a conventional machine and sold as the HT, but then production ceased.

HT were motorcycles produced from 1922 to 1924 by Arthur Hagg of Park Street, a village in Hertfordshire. The initials originally stood for Hagg Tandem (produced under that name from 1920 to 1922).

  • 1922 The Hagg Tandem was an advanced, well-enclosed machine that, although innovative, failed to sell well. It was fitted with a 349cc Barr and Stroud sleeve-valve engine, driving a two-speed Burman gearbox.
  • 1923 Arthur Hagg changed the name of his machine to the HT. He also added a conventional model that sold as the HT Sports and that had the same engine and gearbox in quality cycle parts.
  • 1924 Sales were still poor so it was the final year for the HT.
