I think this bike is kind of cool, its a blatant copy of the Lifan GY-5 which other Chinese manufacturers make versions of, they I would say copy whatever is popular.

I am not even sure the Chinese consider it copying, they may actually buy parts from each other? One may make the frame or in this case the fuel tank which is the part that makes it look just like the Lifan model.

The results is actually a better looking version, sort of an improvement on the original.
