Standard performance metrics for the NSU Quickly included a top speed of 40 km/h (25 mph). Typical dimensions encompassed a wheelbase of 1,100 mm, a dry weight ranging from 42 to 47.5 kg, and a seat height of 760 mm, contributing to its agile handling and ease of use for riders of varying sizes.[7] Key features included a twistgrip throttle for intuitive control, a hand-operated 2-speed manual transmission, and drum brakes on both wheels for reliable stopping power.[6] To ensure compliance with moped regulations, the design incorporated essential safety elements such as integrated lighting, a horn, and functional pedals that allowed propulsion without engine assistance, thereby classifying it as a pedal cycle with motorized support in many jurisdictions.[6] Power output was 1.4 PS (1.0 kW).[8]Design and Construction
Frame and Chassis
The NSU Quickly's core structural foundation is a pressed-steel single spar frame, designed as a box girder formed from welded sheet metal pressings to integrate key components including the headset at the front, seat post tower, motor mounts, and petrol tank attachments. This construction facilitated efficient mass production while maintaining durability suitable for everyday use. The frame's single spar layout provided inherent rigidity, ensuring stability for the moped's typical top speeds of around 40 km/h, and included provisions for mounting pedal cranks to comply with moped regulations requiring auxiliary pedaling capability. Early base models, such as the Quickly N and S, utilized 26 x 2.00-inch wheels front and rear, contributing to a balanced weight distribution that enhanced handling for urban commuting. The steel material choice emphasized longevity and resistance to everyday wear, though higher trims like the S featured chrome accents on wheel rims and other visible elements for aesthetic appeal. As the model line evolved, wheel sizes shifted to 23-inch or 25-inch diameters in later variants to improve maneuverability and responsiveness, while retaining the pressed-steel design for consistency.[9] A key limitation of the base frame was the absence of rear suspension, resulting in a rigid ride that relied on the front leading-link setup, wide tires, and sprung saddle for comfort. While this kept weight low at approximately 42 kg and simplified production, it could transmit road imperfections directly to the rider.[2] Certain sportier variants retained the pressed-steel frame, which remained the standard for most production models.[10]Engine and Drivetrain
The NSU Quickly was powered by a 49 cc single-cylinder two-stroke engine, air-cooled for simplicity and reliability in its moped application. This unit incorporated a carburetor for fuel delivery and flywheel magneto ignition to provide consistent spark without requiring an external battery.[9][7] The engine's standard configuration featured a compression ratio of 5.5:1, delivering 1.4 PS (1.0 kW) at 4,600 rpm, which provided adequate low-end torque for urban commuting. Sport-oriented models increased the compression ratio to achieve higher outputs, reaching up to 1.7 PS (1.3 kW) at 5,000 rpm for improved acceleration. Power variations across models are detailed in the relevant sections.[11][12][13] The drivetrain employed a centrifugal clutch that engaged automatically based on engine speed, ensuring drag-free operation at idle and smooth power application. Power from the engine transferred to the rear wheel via a belt drive, which was low-maintenance and protected within the frame for safety. Pedal assistance integrated a chain drive linked to the bottom bracket, enabling manual propulsion for starting or low-speed maneuvering when the engine was disengaged.[9][7] Gearbox options included a standard two-speed transmission shifted via twistgrip on the handlebar, offering straightforward operation without neutral lock or reverse. Later iterations introduced a three-speed variant for enhanced versatility in varied terrains.[9][11] The fuel system consisted of a tank with capacity varying by model (typically 4 liters for base versions), and relied on mix-lubrication with a 1:40 oil-to-gasoline ratio to maintain internal engine lubrication in the two-stroke design. The exhaust incorporated a tuned pipe to optimize scavenging and improve overall efficiency.[7][14]Suspension, Brakes, and Other Components
The NSU Quickly featured a straightforward front suspension system consisting of pressed steel leading-link forks, which provided basic shock absorption suitable for urban commuting speeds up to 40 km/h. These forks incorporated rubber elements for damping in early models, evolving to include coil springs in later iterations for improved ride comfort while maintaining the moped's lightweight design and compliance with 1950s European licensing regulations that emphasized simplicity over advanced engineering.[15] Rear suspension was rigid in the majority of Quickly variants, relying on the frame's inherent stiffness and a sprung saddle to mitigate road imperfections, which aligned with the era's cost-effective production standards for pedal-assisted mopeds. In luxury models such as the Quickly L and F, a swingarm rear suspension with telescopic dampers was introduced, offering enhanced stability on uneven surfaces without complicating the overall mechanical layout.[16] Braking was handled by internal expanding drum brakes at both ends (approximately 125 mm diameter), operated via Bowden cables from a right-hand twist grip, delivering adequate stopping power for the vehicle's modest performance and adhering to safety norms for light motorcycles. These cable-actuated drums ensured reliable modulation at low speeds, though they required periodic adjustment to prevent fade during prolonged use.[7] The Quickly rolled on pneumatic tires measuring 26 x 2.00 inches front and rear, providing sufficient grip and load-bearing capacity for solo or light two-up riding on paved roads. Optional whitewall tires were available for aesthetic appeal, but the standard black rubber construction prioritized durability and low rolling resistance in keeping with the moped's economical ethos.[7] Auxiliary components included a 6V electrical system powered by a flywheel magneto dynamo, which supplied ignition and basic lighting without the need for a battery, simplifying maintenance and ensuring reliability in wet conditions common to European climates.[17] Lighting comprised a headlamp and tail lamp integrated into the fenders, meeting minimal visibility requirements, while controls featured a handlebar-mounted two-speed gear shifter and twist-grip throttle for intuitive operation by novice riders.[7]Model Variations
