The way I see it, e-bikes are what mopeds always wished they could be - some at least you can run around under your own power and turn on the assist when your legs run out. Others can merely supplement what you put in. As long as nobody pretends that an e-bike is in the same class as a regular bike and starts 'racing' them, I don't have a problem with them at all. They're not for me yet, but ya never know...
