thinking of modifications, i was reminded of some bridgestone picnicas i've seen recently. the picnica was basically designed as a folding leisure or "mamachari" style bike. i remember the first time i tried one at a fleamarket in the east village i was surprised by how heavy and sluggish is was. but, i was also impressed by the quality of the construction. apparently, there were several different iterations: a standard chain-drive version; the famous belt-drive model; 14" wheels; 12 in wheels; and a "DX" model with a rear rack and side folding handlebar stem. plus, a couple of different frame geometries with different lugs. there is even a modern knock-off. here are a few mods i like- some simple and a couple extraordinary ones:



serious mod here with 18" wheels, a beauty:
