So i made 30 kilometers on my bicycle and chain broke, chinese sh*t. I saw people buying 420, 415, 415h chains, and my question is, what is the difference between them?
What chain for 80cc bicycle?

Stock chain will break, make sure the engine in mounted solid to the frame, no gaps between the mount and frame. If not it will continue to break chains.
