HT motorcycles were produced from late 1922 to 1924 by Arthur Hagg. The initials originally stood for Hagg Tandem (produced under that name from 1920 to 1922).
In late 1922 Arthur Hagg changed the name of his machine from Hagg Tandem to HT. He also added a conventional model that sold as the HT Sports which employed the same engine and gearbox as previous models.
The machines did not sell well and production ended in 1924.

The H.T. Motor Cycle Co., Park Street, near St. Albans, Herts.
Probably the old and fuller name of the H.T. - the Hagg Tandem - better describes this model, which is a two-seated two-wheeler designed to overcome the main objections to pillion riding. The extra passenger has a comfortable seat, well forward, and is able to place his feet on the rear end of the main footboards. It is claimed that the usefulness of the H.T. as a solo mount is not in any way diminished.
Other features of note are a simple but extremely strong spring frame, complete shielding of the engine, and adequate mudguarding, a hand-starter, and a foot-controlled gear, which allows the nervous rider to retain his hands on the handle-bars whenever the machine is in motion.
Provision has been made for carrying luggage pannier fashion over the rear wheel.
2¾ H.P. Model.
70x90.5 mm. (348 c.c.);. single cyl. four-stroke; sleeve valve; drip feed lubrication; Binks carb.; gear-driven mag.; 2-sp. gear; clutch, no kick-starter; chain and belt drive; 26x2in. tyres. Price £65.
Right at the other end of the scale is the second model of the H.T., a simple and light speed machine, shorn of all unessentials.
Internal expanding front and rear brakes are fitted to both types, and several other items in their specification are the same, but it would be difficult to imagine a greater contrast than the finished products.
