I've been getting ready to buy my first folder. I looked at a slightly used Citizen Tokyo, rode it around the owner's parking lot - so I didn't get to try many gears. It had a fairly comfortable ride, but it definitely was heavy despite being small. When the owner unfolded it for me, she got the handlebar clipped wrong, so we couldn't get it unclipped to refold it. She wrote me later to tell me that she'd finally got it. Small thing - but gave me a bad feeling about the bike - it should be difficult to fasten things the wrong way - kind of like how it isn't possible to plug most computer cables wrong.
