Zündapp (a.k.a. Zuendapp) was a major German motorcycle manufacturer founded in 1917 in Nuremberg by Fritz Neumeyer, together with the Friedrich Krupp AG and the machine tool manufacturer Thiel under the name “Zünder- und Apparatebau G.m.b.H.” as a producer of detonators (Zünder- und Apparatebau is German for Igniter and Apparatus). In 1919, as the demand for weapons parts declined after World War I, Neumeyer became the sole proprietor of the company, and two years later he diversified into the construction of motorcycles.
Following World War II, Zündapp expanded into the microcar, moped and scooter markets. The company collapsed in 1984.
After the bankruptcy, the entire production line and intellectual properties was bought by Xunda Motor Co., Tianjin, China. They produced small Zündapp motorcycles from 1987 till the early 1990s. Zündapp is still in business, but makes Honda based 4-stroke motorcycles and electric mopeds.
Zündapp also had a technical collaboration with Royal Enfield (India) to build mopeds and motorcycles. A dedicated factory was built at Ranipet near Chennai in the early 1980s to manufacture small, lightweight two-stroke motorcycles to be offered along with their flagship Royal Enfield Bullet. Enfield launched two 50 cc motorcycles first, the step-thru Silver Plus and the 3-speed Explorer motorcycle. Later, 175 cc Enfield Fury (based on Zündapp KS175) was introduced as a performance motorcycle. It had 5-speed gearbox, a hydraulic Brembo disc brake and a sleeveless hard chromed cylinder barrel, all were a first on a motorcycle in that country.
