Dominique Mottas, an avant-garde entrepreneur and motor cars enthusiast, decided at the end of the 1980s to invest in technological and biotechnological fields. Regarding his many projects, he had a new sports car model built. He found the result very interesting design-wise but not sufficiently innovative from a technical point of view.
So the manufacturer went back to his drawing board, and while searching for an idea to satisfy his customer's requirements, he was struck by an exceptional idea: reinvent the wheel. So he equipped his car with 4 empty wheels and presented it to his customer.
Dominique Mottas was thrilled to bits and realized that it was a revolutionary invention. So he decided to patent it, and the hubless wheel, or orbital wheel, was born.
It would take 10 years, from the first patent approval obtained on January 15th 1990 in France and that of the Japanese patent, to put the finishing touches to this project worldwide.
Since then the hubless wheel has been ready to be presented to the general public and exploited throughout the world.

Idea : Reduce the rotating part to a bare minimum.

Principle : A bearing with a thin section and large diameter (about 300 mm).
The rotating part: a tyre, a centre-free rim and a brake ring all integral with the rotating outer ring of the bearing.
The fixed part: the non-rotating inner ring of the bearing on which the vehicle's steering system is directly attached.

Result : An empty wheel that is free of midwheel structural constraints and that presents a series of advantages and technological breakthroughs.
