La Motosacoche Bicycle Engine Poster
In 1899 the brothers Henry and Armand Dufaux from Geneva, Switzerland, designed a little four-stroke engine. This compact unit could be bolted into the frame of any ordinary pushbike: The 'Motosacoche' which approximately means 'engine-bag' was born! Very soon the quality and practical utility of the invention became known even far beyond the swiss territory.
