it's either brompton or strida. other bikes are just dumb. tern. dumb. moulton dumb. pacific cycles dumb. dahon dumb. birdie dumb. bike friday , kinda dumb. old raleigh folding tanks ....the list goes on. any bike with under 16"" wheels is also totally stupid . retardedly so, unless it's for some niche clown world where bumps don't exist and you don't ride the thing farther than a mile.
