Monet Goyon - William


1948 Monet & Goyon Motorox 34cc on William bicycle. Compare: Monet-Goyon

It was not sufficiently tested to iron out various running issues before it was launched, as a result of which it developed a bad reputation.

They refused his ideas and went with the Motorox instead. As a result, Morel moved to Motobecane and his design promptly became one of the most successful cyclemotors of all time – the Mobylette!"
