A Brief History of the Marque
Made in Austria 1922-1925
Manufacturer: Bison Motorradfabrik Ges.m.b.H.
Built by Oskar Hacker employing horizontally-opposed engines from BMW mounted longitudinally in Douglas fashion, the machines were otherwise conventional apart from the low seating position and the optional spare wheel - a very useful extra in the days when a flat-tyre during the course of the ride was a very frequent occurrence.
The business was sold to Wilhelm Lovrek, of Perchtoldsdorferstraße 9 Liesing, Vienna, in 1923. By 1924 sales had diminished due to the worsening economic situation and possibly also due to supply problems with BMW.
The firm folded in January 1925.
Bison also used engines from SMW, Bosch Stockdorfer Motorenwerke AG, Stockdorf, near Munich. This engine was used in the early 1920s by other obscure brands like Linsner, SBD, and the wooden-framed Hirsch. (1) Notes: 1. Sergio Scalarandi
