Don't know exactly how that phrase (title above) originated but I think it means that you don't really need it, i.e. fishes don't need bike to swim. I found out to fix my Raleigh mountain bike (front, rear derailleurs + shocks, etc) cost more than a new bike so to get something to just ride around town for errands, I went looking for one. Beach cruisers, fixed gear bikes, other mountain bikes...I can't make up my mind...until I saw this Bianchi. In celeste green color, of course. A 3-speed job with fenders and chain guards! It rocks and it's a work of art as well. It's so cool even a fish would want (not necessarily need) one.
