No break down at all. Mine simply folds together in maybe five seconds. It loads on top of my other gear in either my Expedition or Scion XB. If you have a really small car it might not fit. In that case I would use the one I made myself out of old parts. It folds up in about 20 seconds and takes virtually no room at all.
It's supposed to be really cold tomorrow, so maybe I'll make a video of it.
