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.

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.
