This stylish vintage Italian folding bike was called the "Duemila" or "2000" in English. It was made by Cesare Rizzato & Co. in Padua, Italy and introduced to the public with a futuristic space theme at the Fiera di Milano trade fair in 1965. Cesare Rizzato went onto make other folding bikes under the "Ceriz" brand name in the 1970's.
