Holy Crap!! I just linked this video in another forum. I wouldn't classify it as "self-charging", since there are no batteries. But I'm interested to hear more about it, just out of curiosity, because there is no way I'm purchasing an electric bike. However, I understand how some can look at it that way. I do like the use of simple capacitors in lieu of batteries. Although they admit there are issues for climbing, which they are working on.
