Ariel, 1932, sidecar

1932 – Ariel “sidecar” – England

Ariel is one of England’s oldest companies, one of its founders was J. Starley to whom we owe the majority of innovative inventions on bicycles back then (for instance, tangent-spoked wheels with Hillman). The Ariel name comes from the spirit who appears in William Shakespeare’s play The Tempest to highlight the lightness of Ariel bicycles. The company later started producing motorcycles and cars; in 1905 it was chosen to represent England in the International Cup. Ariel entered the history books as the first company to believe in the “Square Four” project by E. Turner.

The Square Four involved the revolutionary use of four cylinders arranged at the four corners of an imaginary square, as in the model shown, instead of a regular inline layout. The engine debuted in 1931 and wasn’t very successful at first, the project still needed to be perfected and Ariel managed to overcome the crisis thanks to the tenacity of John Sangster who reopened the factory with his money with the name Ariel Motors JS Ltd; after thrity years of activity, the English company stopped the production in 1966.
