After some failed attempts, I bought the bike 55 years later, which was in terrible condition, but had a lot of difficulty restoring it as the parts are very rare. Known as Bleckbannane, it was produced by Zweirad Union A.G., in Nuremberg, between 1961 and 1965, and included 3 models: Hummel, Kavalier and Express. The engine of this model, a 4.2 HP, is the most powerful, but has an air turbine which allows for cooling.
