Friedhelm Zabel had been involved in motorcycle racing for some time before he began building his own engines. Early versions were Maico-based 620cc units, and in 1988 he built a water-cooled 685cc two-stroke for motocross sidecars producing over 80hp. Despite its extraordinary output, it weighed a mere 30kg. It was an immediate success.

Zimmer & Gehlich, Zetge Fahrzeugwerke, Moys-Görlitz
Built good quality lightweight motorcycles and three-wheelers using engines of their own manufacture in 142cc and 173cc capacities, and also two-strokes from DKW in similar sizes. The three-wheelers had the engine mounted forward and above the front wheel and had such names as Zetgelette and Zetgemobil. The solo Einheitsmodell had an unusual and quite shapely appearance.

Manufactured by Klotz & Becker of Leipzig-Lindenau, 1926-c1932
Used Kühne and Küchen engines, Hurth gearboxes and their own frames. Some machines were supplied with sidecars using the Stoye chassis.
It is thought by one German writer that some 500 machines were built, of which there is only one survivor.
Advertising text, date unknown: ZEUS-MOTORRADBAU, Klotz & Becker, LEIPZIG-LI. Lützner Str. 81 The advert mentions 350 ccm and 500 ccm engines, and illustrates what appears to be a Küchen powerplant.
There was a Becker firm in Dresden in the 1900s, and a Klotz in Stuttgart in the mid-1920s. It is not clear whether either of those firms are related to this one.
There was also a Zeus built by Linser, 1902-1906.
