Cateye is the only bike that ive seen that uses a dual chain setup. One thing about the china bike is that they will make match body parts on bikes. I have a X2 bike that has X5 side plastics. Also i have a X1 that has a X2 chain and sprocket setup. So they use whatever they have laying around the warehouse at the time. Also with the X7 uses a 9" rim setup and the frame is made to take a 49cc or 110cc motor. Also the pull start on your bike is on the wrong side to be a X7. Cateyes use a 6" or 6.50" wide rear rim with a free hub on the rear.
Swheels - X7 build. Look at the frame on it and the footpegs and rear swing arm. Way different.
