That thing is 33lbs? Dear gods.
the "unexpected fold" refers, I suppose, to Raleigh Ternty-type folders of the 1970s and 1980s, often badly made and always badly maintained by their idiot owners. There's no reason for even that old and crappy design to suddenly fold unless the user cocks it up.
But then, fear, uncertainty and doubt have always been great marketing tools. Just look at Microsoft.
