I'm in China right now, the land of bicycles. You can buy brand new fully suspended mountain bikes with disc brakes here for what you would pay for someone's used junk on craig's list in the states! But then it costs 4 times the bike for shipping to get it back to the states.
There is a particularly interesting tandem sold only in the UK that I think would make a fine Cruzbike tandem, but I can't get anyone to ship me one. I'd pay the stupid shipping plus the cost of the bike to get it here; I really want a CB tandem for my wife and I to ride. After riding the CB, my Vision R82 tandem just doesn't get it.
I will check around here, but my research is slow and hampered by the language barrier. Is the bike you pictured here the one you are looking for? If I find something I'll send you a picture. I'd be happy to send it to you. I'm retired and time is not an issue!
