The latest generation of DI BLASI folding bicycles: same full range of standard equipment, same sturdiness, same simple and fast folding as the R4 model folding bicycle, only much smaller when folded and longer when open, thanks to a patented system for automatic folding of the front fork. The folding bicycle mod. R5 is also available with a stainless steel frame (AISI 304), suitable for use near the seaside.
