You can either go and check out the offerings from Flying Pigeon NYC (not affiliated, but I do know of them), or you could do a google search. FPNYC is I think the most famous of the US importers of these bikes, but there are others out there.
My question is, what do you want to do with it?
A Flying Pigeon is a roadster, not really suitable (in my experience) for trail-riding.
