Zündapp was a famous German motorcycle brand. The company was originally 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. 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. The company folded in 1984.
The first Zündapp motorcycle was the Z22 in 1921, the "Motorrad für Jedermann"
(motorcycle for everybody), a simple and reliable design that was produced in large
series. Zündapp's history of heavy motorcycles began in 1933 with the K-series. They
introduced the closed engine case, a novelty at the time. (The "K" stands for
"Kardanantrieb", i.e. enclosed driveshaft with two universal joints, a type of
drivetrain, which these models featured.) The series encompassed models from 200 to
800 cc displacement and was a major success, increasing Zündapp's market share in
Germany from 5% in 1931 to 18% in 1937. From 1940 on, Zündapp produced more than
18'000 units of the KS750, a sidecar with a driven side wheel and a locking differential
for the German Wehrmacht.
Starting in 1931 Ferdinand Porsche and Zündapp developed the "Auto für Jedermann"
(car for everybody), which was the first time the name "Volkswagen" was used.
Porsche preferred the 4- cylinder flat engine, but Zündapp used a water-cooled
5 cylinder radial engine. In 1932 three prototypes were running. All three cars
were lost during the war, the last in 1945 in Stuttgart during a bombing raid.
After World War II, the company gradually shifted to producing smaller machines,
for instance the "Bella" motorscooter, still a relatively heavy machine for its
type. The last of the heavy motorcycles, and incidentally also one of its most
famous models, was released in 1951: the KS601 (the "green elephant") with a 598 cc
two cylinder engine.
From 1957 to 1958 the company also produced the Zündapp Janus microcar.
In 1958 the company moved from Nuremberg to Munich. Subsequently, the company
developed several new smaller models, gave up the development of four-stroke
engines and only produced two-stroke models. Initially, Zündapp scooters and
mopeds sold well, but later sales declined, and in 1984, the company went
bankrupt and closed...
