Chinese Motorcycle?

I realize this looks like a good deal to someone that is unfamiliar with motorcycles, and those are the only people buying these bikes. You can pick up a nice low mileage Ninja 250 used for around the same price and it will last you 10 times longer than this bike. My biggest concerns would be reliability and parts availability. Who even knows if this company will be around a few years from now. But that is your decision to make. To answer your other two questions, I would guess top speed is around 70 - 90 and MPG is in the 60 -70 range.
