It actually looks like it's using fixed wheel hubs in the video, to me.

  Hmnn, I'm not quite sure, there was a lot of coasting and some slight back-pedaling going on in the video... Also, thinking about how this thing works, I'm not sure it would work so great on a fixed gear bike.... if you're strapped/clipped in, you definitely want to be in full control of how fast you're pedaling, random boost might throw you off balance or force you to pedal awkwardly

    Ug. I had completely mistaken 'single gear' for 'fixed wheel'. Sorry, all my bikes have derailleurs.
