The front forks of the Quickly were made from pressed steel and were fitted with leading-link suspension.

[2] The motor unit included a 49 cc (3.0 cu in) two-stroke engine, a two-speed transmission (three-speed on some models), a bicycle pedal assembly to start the engine and assist propulsion up hills, and a centrestand.

The Cavallino had a tubular steel frame similar to a conventional motorcycle, but without a downtube.

[3][6] The S was basically a N with larger fenders, a speedometer, a side stand, and chrome-plated rims.

The Cavallino had telescopic front forks, a dual seat, a three-speed transmission, and 23 × 2.25" wheels.

[3] It had a unique frame, futuristic styling, a new leading link front fork with the front fender as a structural component, a three speed transmission, and a high-compression (6.8:1, 1.7 PS (1.3 kW) at 5000 rpm) version of the Quickly's motor unit.

[3][5] The TT used the frame from the Cavallino and the front suspension (including structural front fender) and high-compression motor unit from the Quickly T. The Quickly TT mopeds were manufactured from 1959 to 1963.

It was similar in styling and appearance to the S2/23, but it had rear suspension combining the swingarm from the L with the tall spring/damper units from the Cavallino and TT.
