    Very clever. The bike seems to be supported on top of the wheels, not the axles. So the frame does not jump up and down much as the wheels seem to be designed so that the distance from the ground to the top is constant.

    The front tire may be a 4 bar linkage, the axle moves foward and back to keep the distance from ground to top constant.

    The world needs a video of this thing.
    2000 Montague CX, I do not recommend it, but still ride it.
    Strida 3, I recommend it for rides < 10mi wo steep hills.
    2006 Rowbike 720 Sport, I recommend it as an exercise bike.
    1996 Birdy, Recommend.
    Wieleder CARiBIKE (folding), decent frame.

    "It seems a bit crazy to reinvent the wheel, but that is precisely what the Chinese inventor Guan Baihua has done. Although his new set of wheels have a little twist to them. The 50-year-old military officer from Qingdao has devised a rather curious new bicycle. Instead of circular wheels the bike has a pentagonal wheel at the front and a triangular wheel at the back.
    He believes that people will be drawn to the bike because it requires more work to cycle and therefore will provide more exercise for the cyclist than a conventional bike."

    an exaple of a good idea gone bad. the wheel has been round for a couple thousand years for a reason.
