I have a Dahon folding bike. I recently bought a used one, however it seemingly was damaged in the mail, the front part of the frame seems to have been moved up relative to the rear by a few mm, so it wont close (unfold all the way) now. See picture below, the middle center piece under the chrome latch cover (front part of frame) overlaps the top metal piece on the other side (rear) of the joint. The middle is no longer able to go in between the metal pieces on the other side (rear) of the joint, it hits the top one. Also wasn't sure if I should post this question in the bicycle mechanic section..
