Named in a clever play on his family name (spelled backward), Robert Hannoyer conceived the 1951 Reyonnah Prototype N°1, featuring an innovative foldable front-wheel design that allowed it to maneuver into compact spaces. Originating from an era of fuel and material scarcity in France, the Reyonnah exemplified the challenges of its time. Crafted for two occupants, this uniquely engineered car, unfortunately, never entered mass production due to a lack of manufacturers willing to undertake the ambitious project. Hannoyer's tests revealed impressive capabilities, demonstrating that the 1951 Reyonnah 175 Prototype N°1 could cover 50 kilometers at an average speed of 95 km/h.
Our Reyonnah is equipped with a 175 c.c. 1-cylinder, air-cooled, 4-stroke engine, 4-wheel hydraulic brakes, and independent suspension—a testament to the forward-thinking designs of its era.
