A Brief History of the Marque
Manufacturer: Fahrradwerke Graz Puntigam
Franz Weiss junior began building bicycles in 1934 and became an important producer during the war years and the early postwar period. The Junior marque was chosen apparently due to the fact that his father, Franz Weiss senior, was also involved in the bicycle trade.
In 1938 the first motorised bicycles with 98cc Saches engines were produced, but ceased quite soon after the outbreak of war. It would appear that production of Lohmann-engined mopeds resumed on cessation of hostilities, but tragically Franz Weiss jun. was killed in an accident in 1951.
Franz Weiss senior then took over management of the firm until 1961 when he handed control to his 23 year old grandson, Franz Weiss. Confused yet?
Bicycle sales were falling off and the moped was very dated. The firm slipped further into debt and eventually collapsed in 1975.

A Steyr Junior c1952 was listed by Bonhams which features an identical fuel tank and logo to the Franz Weiss Junior.
Bonhams say of this machine, "...from the Ehn museum is this diminutive cyclemotor engine, mounted on what is described as a pre-war, Austrian army Steyr ‘waffenrad’ bicycle. Museum-catalogued as a Steyr 'Junior', this is a re-titled German Lohmann diesel engine. The Lohmann has more of a resemblance to a high-speed model aircraft engine than to a cyclemotor, both in its diminutive 18 cc capacity and compression-ignition operation."
