He didn't say the telescoping thing went down, he did intimate that the hinge folded while riding. That is a valid complaint. That is something the Dahon handlepost became notorious for when they went with aluminium versions. The steel latch was a whole lot better but they abandoned careful safety-backed design in the aluminium versions which eventually led to a recall.
I had such a Dahon with early aluminium handlepost and got rid of it quickly. I also had an OEM Dahon-made folder which had the safe steel version. And I had a Downtube Mini and it was blazingly obvious that the Downtube hinges were designed with reliable inherently safety-backed latches. Of course they could still just break right off but the hinges just don't open when they are not meant to.
Nothing wrong with this thread except for the calling for it to be closed.
