If you’re not bad, Max G2 ever starts banging on start or stop in the back. You will need to remove the side covers. There’s a screw underneath the reflector in the back and screw underneath the rubber cap. Once you remove the side covers you will need to tighten the wheel screws and you should also tighten any screw you see, like for the fender or anything else. I didn’t touch the shock screws though. Put the cover back on and you should be good to go no rattling no banging.
