It's a pretty cool set up. That bike and one of the Paketas are both built with just two couplers and fit into a a standard size bike case (as opposed to the S&S cases).
I came to a similar conclusion thinking that the stoker bars were integrated with the stem and seat post. It would be hard to get them packed into a case with the back half of the frame and have the cabling and hydraulic line still attached. A very cool setup though if you weren't planning on packing the bike up. Did Kent give you any idea as to what the integrated post, stem and stoker bars weighed?
