Thanks for the responses everyone. I don't know much about this bike outside china so i can't really help there. I'm also unsure about the puzey/galaxy connection but it really looks like they're the same bike.
there's a thread on chinese bike forum with pics of the galaxy factory down in guangdong and of the water cooled version coming out later this year. judging by the pics it really looks the exact same as the puzey:
