NSU, along with BMW and DKW is one of Germany’s oldest brands. Their first bike was introduced in 1901. The NSU (Neckarsulm Stickmachen Union) bikes sold well until WW1 when they were forced to make munitions.  But by 1922 they were back to bikes at full capacity. In 1938 they produced over 62,000 bikes. During WW2 they produced bikes for the military but following the war, they were back in production for public bikes. From then until 1963 they produced varied street and race bikes. The Sportmax and their streamliners won championships and speed records. NSU is also famous for pioneering the use of the Wankel rotary engine in motorcycles.
