I was very confused by that as well.

I studied the video, and the only thing that I can conclude is that he simply unbolted the pedals from the chain ring. The pedals would therefore not be doing anything at all except support the rider's feet.

The site says "pedaling recharges the battery." This would require re-bolting the pedals back on.

It's hard to see angles that can really make this clear. Maybe there are some freewheels that let the chain ring spin independently of the pedals, which makes no sense to me.
