Spotted at MIT and in the South End - the Strida folding bike. The man in the South End let us take his for a test ride and we were amazed at how smooth and comfortable the ride is. The belt drive keeps the bike clean (no chain lube) so it's easy to carry around, and small enough to hang in your closet. The only downside is that it all hinges on a single pin connecting the lower bar to the headtube. This possible failure mode made me a bit nervous, but not so nervous that I didn't enjoy riding the little thing! I guess it seems more like a transportation tool than a true bike, which I know sounds a bit odd.
