Thanks all for the informative input. Makeinu, I'm about 200 lbs @ 5'11". Yeah, I could stand to loose a few...optimal weight for me would be closer to 180 or even 175. And that was one of my concerns regarding the folder, whether or not I'd be able to get full leg extension when pedalling.
I've actually become more interested in the notion of getting a full sized bike and some anchor chain, and just leaving it in plain sight at the bus terminal.
I can't say enough for buying high quality goods, whether bicycles, back packs, or skis. Buy as good a quality as you can afford. I was just hoping this cheapo might have been an exception to that rule...should have known better!
