Ariel was a bicycle, motorbike and automobile marque manufactured based in Bournbrook, Birmingham, England. Car production moved to Coventry in 1911. The company name was reused in 1999 for the formation of Ariel Ltd, a sports car producer.

The first Ariel to be fitted with an engine was in 1898 when a powered tricycle appeared. In 1901 the first Ariel motorbike proper was launched powered by a 211 cc Minerva engine.

A range of motor cycles was made with engines either bought in or assembled to other peoples design until the 1926 season when a new designer, Val Page, joined Ariel from JAP. Page created a pair of new engines for the 1926 season which used many existing cycle parts and then redsigned the cycle for 1927. These Ariels are known as 'Black Ariels' (1926 - 1930) and were the basis on which all Ariel 4-stroke singles were based until their demise in 1959 (except the LH Colt of the mid 1950s). During the 'Black Ariel' period the Ariel horse logo came into being as did the slogan 'The Modern Motor Cycle'.

Ariel 1000 Square FourThe Ariel Square Four with 500 cc engine designed by Edward Turner first appeared for the 1931 season, but around this time the company went into receivership and then a new company was formed. The Square Four became a 600cc. The Square Fours had overheating problems with the rear cylinders which resulted in distorted heads throughout their history. A redesign in 1937 resulted in a 995 cc OHV version designated the 4G.

In 1939 Anstey-link plunger rear suspension was an option. It was still available when production restarted in 1946, with telescopic forks replacing the girder forks.

In 1949 the Mark 1 Square Four had cast aluminium barrels and heads, instead of cast iron. With the lower weight the bike was a 90 mph plus machine.

In 1951 Jack Sangster had sold Ariel and Triumph (bought in 1936) to the Birmingham Small Arms Company group (BSA), and joined their board. By 1956 Sangster was voted in as the new Chairman, defeating incumbent Sir Bernard Docker 6 to 3. Sangster promptly made Edward Turner head of the automotive division, which then included Ariel, Triumph , and BSA motorbikes, as well as Daimler and Carbodies (London Taxicab manufacturers).

In 1953 the Mark 2 Square Four had a redesigned cylinder head, and was capable of 100 mph.

In 1959, to the dismay of some motorcyclists, Ariel dropped its four-stroke engines and produced basically two models, the 250cc twin cylinder two-stroke engined Arrow and Leader models. There was also a 200cc Arrow version made for a short period. These engines and frames, completely new to Ariel, were copies of the pre-war German Adler models. The designs had been claimed by the Allies as part of war reparations after WW2 in a similar way in which BSA used the German DKW design as the starting point for their BSA Bantam models. To give Ariel credit, the Arrow and Leader models were an attempt to bring the company up to date having recognised the threat from the new Japanese imports.

The Leader had a fully faired body from the headlamp aft. The Arrow was more open, though it kept the enclosed chain case and deep mudguards.

Ariel motorbikes ceased production in 1967.

In 1970 BSA used the name for the "Ariel 3", a 3-wheeler 50cc 2-stroke moped, different at the time because it was a tilting vehicle. The front half was hinged to the rear and could tilt into corners whilst keeping all three wheels on the ground. Production of the Ariel 3 was short and was dropped along with the Ariel name shortly afterwards.
