I share a shop with chris and a few other guys, we get and fix some bikes. The only one I know that's good and running now is a pretty rad but not easy 2 speed gripshift sachs balboa. I think we could sell that for like 500. It's got no brakelight or blinkers but good head and taillight, just use hand signals. The gripshift takes some getting used to. it's technically not moped it goes around 35 and 2 speed manual shift, but has pedals, you can register it as a moped and absolutely no cops will ever give you trouble. Actually did get pulled over on it last week and they were totally fine with it. (actually just pulle us cuz they thought we were on non-streeet-legal dirtbikes - downtown/asia town area)
Anyhow, there's also a pretty ratty kriedler flory might be selling soon, and a puch murray, and some tomos's maybe some other stuff, theres a lotta bikes just needing some finishing ouches. I guess what's your price range and how much time you wanna put in? I tryn get at least new cables and tires on stuff, but ifyou're cool with crappier bikes they're way cheaper.
I'll take more photos today.
