If you somehow made it into the Complex dot com headquarters recently chances are you would have seen someone gliding through the office on the IO Hawk. And if you were really lucky you would have seen someone bust their ass while trying to master it. The "intelligent personal mobility" device can be difficult to take on, though a few of our staffers have become pros. To share the fun we took the IO Hawk out of the office and had New Yorkers try it for the first time. And to add another degree of difficulty we had them tackle the SoloWheel as well. Watch the hilarious and difficult exercise in balance above.
