I've been to the Pedaling History Bicycle Museum, in New York. At least when I was there, maybe 5 years ago?, it was a small, crowded set-up, more like an enthusiast's "home-made" display of his collection. The photos on the web site give you a pretty good idea of what the displays are like. But lots of interesting bikes, both very old and moderately so (say, into the 1960's). Worth a stop if, say, you're on your way to/through Buffalo from Chicago, Giorgios.
