The NSU Quick is a "motorbike" (motorcycle with pedal cranks) that NSU built from 1936 to 1953. 235,441 pieces were produced during this time with only minor changes. According to today's definition, the Quick is a light motorcycle in terms of road traffic law .

frame

The frame construction is essentially a bicycle frame, but with thicker tubes to withstand the load from the engine and the higher driving speeds. In 1936 there were initially two versions: an NSU = Quick = women's bike (as the advertising spelled it) with a medium-high step-through and a clothing protection net on the rear wheel, as well as an NSU = Quick = men's bike . The front wheel of both versions is mounted in a parallelogram or trapezoidal fork with a steel compression spring. There is no rear suspension. The driver's seat is a height-adjustable compression spring saddle.

engine and gears

The Quick is powered by an air-cooled NSU single-cylinder two-stroke engine with a nose piston . The power of the small engine (98 cm³) is 3 HP. The two-speed transmission is interlocked with the engine. It was shifted initially with a small hand lever on the handlebar and from 1952 with a twist grip.

The NSU Quick has two drive chains: on the right one for possible bicycle use and on the left one for the motor drive. To start the engine when stationary, the Quick is jacked up so that the rear wheel can turn freely. When the engine is running, the bike is braked, the stand folded up and, if necessary, a passenger can get on. In solo operation, it is easier to “start pedaling” with the gear engaged and the clutch pulled and to engage the clutch when the momentum is sufficient.

The first models of the NSU Quick had a coaster brake like the bicycle, which was replaced by an inner shoe brake as early as 1938, but was still operated via the pedals or the crank.
