of Wells Street, London

Economic were motorcycles produced from 1921 to 1923.

The engine originated in the United States and was used to power a World War I generator. It was an interesting 165cc flat-twin two-stroke and the crankcase was split on the centre line with each half cast in one with a cylinder. It cost just 28 pounds.

Suplus engines were available after the war, and Economic installed these firstly in-line and then across the frame. It had friction driven transmission.

It was not marketed for long, although the reasons for this are unclear. It may have been because the engine was not reliable, or perhaps because of lack of supplies.

1920-21 Produced a small number of three-wheelers
