Today I noticed that the stem post hinge on my Dahon Boardwalk S1 was loose and wobbling, so I "tightened" the hinge bolt further into the hinge nut, which I now know was counterintuitive, as it gave the hinge even more play. However, before I realized this, I had attempted to fold my stem post back into operating position, and in doing so, the end of the bolt was bent by the frame underneath the hinge due to the fact that I had tightened the bolt so far.
Now I have a bolt that is bent right at the end of the threads of the hinge nut. I tried using downward force with a tool to bend the bolt back, but I have so far been unable to do that. Until I am able to either straighten or cut and replace the bolt, I am unable to ride the bike, as the stempost won't fold up. Any ideas how to remedy this situation? I'd greatly appreciate it.
