Buying and shipping Flying Pigeon bike to Europe?

I%26#39;ll be in Beijing in mid-April and am interested in buying a Flying Pigeon bike.

So:

1, Where in downtown Beijing can I get a new Flying Pigeon bike (I%26#39;ll stay close to the main train station)?

2. Do they come in a box or all ready to bike away with? If I need to pack it, can they help me with that at the post office (is there one at the train station?)

3, Roughly how much would it cost with surface mail to Europe? (Is it worth it? :)
