It is a folder, it is the same exact design originated by mongoose, that just takes a klein mantra, top-tube, and mate a second head-tube at the back for the seat-tube to go through, so the rear end can swing around beside the front... antique design with a new name thrown on it!
hummers bike was a folding bike im pretty sure, look at the top tube if you don't believe me a metal bar for the back wheel goes through it and then has a twister thingy.
