There is an opportunity to move both as a bicycle, so and as motorcycle.Ernst Sachs was an avid and competitive cyclist. Having apprenticed as a toolmaker and later earning experience as a watchmaker and mechanic, he had plenty of ideas regarding re-engineering parts of the bicycle.
By the end of the 1910s,Fichtel & Sachs employed several thousand people and had become one of the largest ball bearing manufacturers in Europe.
Along with the bearings and a significant bicycle parts business, the firm had entered into small-engine production, typically the type fitted to motorized bicycles and small-bore motorcycles.
