Need help identifying an old bicycle, unusual frame
Looks like a generic beach cruiser - not very old either.  The brazed lugs on the downtube suggest it was a geared bike, converted to single speed.

The V brakes say its no older than the 90s, and probably post-2000.  

Its doesn't appear to be anything specifically Italian.  Still if it rides nicely, then ride it.   There's likely no museum or vintage nature there.
