The classic DI BLASI folding bicycle. Since 1974 it is well known worldwide as the bicycle that is the easiest and the fastest to fold. It takes only 5 seconds and three easy steps: push the saddle down, lower the handlebar and fold the pedals. Done! The folded bike fits almost anywhere: in the boot of a car, on the train, on a boat, in the camper van, etc. It is just as easy and fast to turn it back into a practical bicycle. Thanks to its one-piece central bar, it is sturdy and equipped with very efficient drum brakes and a full range of standard equipment: foldable pedals, change speed system, luggage rack, dynamo-powered front and tail lights. The folding bicycle DI BLASI mod. R4 is also available with a stainless steel frame (AISI 304), suitable for use near the seaside.
