In 1916, in the middle of the first world war, engineer Joseph Monet and Adrien Goyon, a wealthy inhabitant of Macon, formed a partnership with the aim to start the production of three wheeled vehicles for handicapped and immobilized people: a market that would be fast growing till the end of the war in 1918. The firm of Monet&Goyon was established on April 2nd, 1917. Business went well, and in 1919 a motorized version of their vehicle was brought out, powered by a 117 cc motorized wheel. I n 1922 the company managed to get the production rights for the popular British Villiers two stroke engines. Monet &Goyon was very successful in races with specially tuned Villiers engines; they won the French championship every year between 1924 and 1927. They also set a number of world records with these machines. From 1925 on MAG engines were also utilized; to such an extend that M&G became a top customer of the Swiss factory. T wo “Supersport” models were available, the 350 cc GA with bore x stroke of 72×85 mm and the 500 cc HA with bore x stroke of 82×94 mm.
