Rosario Di Blasi (1919-2008) began developing a folding scooter in 1952. In postwar Rome, bicycle theft was common, as any kind of personal transport was in short supply. The story goes that while carrying his bicycle up the 8 flights of stairs to his apartment, Di Blasi thought the idea of a folding bike would be easier to transport.

From 1949 to 1962, DKW produced a van with a trailing-arm rear suspension system which incorporated springs in the cross bar assembly.

The Dodge Viper was conceived as a futuristic interpretation of a classic American muscle car. During the development stage, it was decided to utilize Lamborghini, then a Chrysler subsidiary, to cast a prototype aluminum V10 engine based on their truck drivetrain and modify it for performance car use.

In 1977, as a hobby, Mr. Duport built a prototype, a Microcar powered by a Lombardini 510cc diesel engine. The car was well constructed, although the only part made by Duport was the chassis.

Danish inventor, musician, blacksmith, and cyclist, Mikael Pedersen (1855 – 1929), believed conventional bicycles were "weakest where they ought to be strongest and heaviest where they ought to be lightest.” He, therefore, restyled the conventional bicycle to resolve what he saw as the most troubling elements of design.

Production of the 3800 continued until 1988 when VéloSoleX stopped manufacturing mopeds. However, in 2004, the Cible Group purchased the brand and launched the e-Solex, an electric bicycle, notably designed by the famed Italian coachbuilder Pininfarina.

Anton F. Erickson built this streamlined car in his garage in Dayton, Ohio right after the end of World War II.
