Di Blasi Folding Motorcycles and Scooters

Available in both two-stroke and electric versions.

A Brief History of the Marque

The Italian firm manufactures folding mopeds, mobility scooters, bicycles and tricycles.

Rosario Di Blasi, a pilot with the Italian Air Force during the war years, published an article on rotary engines in 1942 which predated the Wankel. Soon after the war he developed the idea of a folding bicycle which soon became a folding motorcycle, and the first such machines were built in the early 1950s.

A machine was presented at the 1968 Turin Auto Show, a folding tricycle named the Dibla 7, powered by a Zanetti engine.

Production began in 1973, and these were presented at that years' Milan Show. In 1974 they were displayed at the Cologne show, and a German importer was selected. As a result, some 80-90% of the the factory production went to Germany where they became known as the R2 Paperino, powered by a single-speed 49cc Franco Morini engine. Paperino is the Italian name for Donald Duck, and the model name has been used for other Italian machines including those of IMN of Naples.

The R7 appeared in 1979, with a a new engine built in-house by Di Blasi.
