Actually Riding It (Score 1)

How the heck do you ride it?? Where do your feet go? Where do your legs go? Can anyone point to a picture of said device populated by ordinary bipeds?

I realise that a photo showing a real, live human being on it might detract from their carefully composed marketing cool, but hey c'mon guys! Where do I fit on it? How do I fit on it? Where do I put the babe in leathers with a taste for high-tech exotica?
