Puch Magnum Moped

This is the third time my magnum frame has cracked. You may have heard of the Magnum weak spot. It’s where the swing arm meats the frame. I have welded up a few peoples magnum frames and they hold together fine, but mine keeps breaking! WHy? you might ask.

THis time it also broke on both sides, through my old welds. welds can be brittle and that may be why. It could have broke originally because of a wobbly spoke wheel. who knows. some have speculated at other causes. . .
