folding bikes rock (especially mine). mine has 24" wheels, so it is about 5" shorter than a 700C bike with the same wheelbase. This means it fits into a small space in my flat between two book shelves and my wife would not be happy with a giant 700C bike lying round our tiny flat. Also, the smaller wheels make the bike much more resposive, but not as twitchy as the 20" dahon I used to ride. I hardly ever fold up my bike, but it has been great at night in the rain when I get a puncture and I am not in the mood to be messing with a patching a muddy innertube, just fold it up and hop on the bus home.
