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.
In 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.
Two “Supersport” models were available, the 350 cc G with bore x stroke of 72×85 mm and the 500 cc H with bore x stroke of 82×94 mm.
