The British Anzani company existed for over 70 years and in that time made engines for everything from aeroplanes to mowers to powered bicycles, to cars, motorcycles, ploughs and outboards.The history of BA is in some part the history of the 20th century. Born in the golden age of pioneering flight at the beginning of the century through the tragedy that was the First World War and into the optimism of the post World War II boom and beyond.But who were the characters that built the company? Who designed, who drove, who flew and who steered the products and the company for 70 years? Here is the story. We hope you enjoy it

British Anzani Engineering were a very progressive and innovative engineering company in their day, covering bicycles , motorbikes and speed boats. More information here :

In 1939, British Anzani Engineering produced a prototype BAE Powerplus clip-on motor attachment for a standard pedal cycle.  The engine was described as a 61cc undersquare two-stroke of 44.5mm bore × 39mm stroke, driving the rear wheel by friction roller on the tyre.  A clutching function could be enabled by lever, which raised and lowered the roller into engagement with the tyre.  Back in the age of first generation autocycles, this prototype BAE cyclemotor was quite a visionary concept, but failed to reach production due to intervention of the war.

The cyclemotor engine was put aside as the need for increased home food production created an immediate demand for more innovative horticultural equipment.  This resulted in introduction of the Iron Horse two-wheeled tractor in 1940, and British Anzani also produced their Super Single outboard motor, supplying 50–60 per month to the Admiralty.  It also developed flexi-driven propulsion systems for engine driven landing craft, and performed other contract work for the Air Ministry.
