Bernhard Sobotta calls his invention The Cercle. Unlike other camping bikes that pull a trailer, The Cercle has its bed frame in the middle of the vehicle. It unfolds to provide an adequate sleeping space and a table, the latter of which has a built-in steel ring for a camping stove.
I can think of a few post-apocalyptic scenarios in which The Cercle would prove useful. Maneuvering it could be too cumbersome during a zombie apocalypse. But, in an empty Earth event, The Cercle could provide the mobility necessary for foraging. My greatest concern would be providing real protection for the sleeper from two and four-legged predators at night.
