Human power is human power. Motors are motors. They are totally different things. If we don't agree on that basic fundamental premise, I don't know how to respond. Have fun on your ebikes, and please be courteous when you pass us old guys on the bike path riding slow on bikes with low gears. This discussion has been very enlightening for me. I didn't understand the appeal of ebikes other than for commuting before. It never occurred to me that there are people in the world who think motors are essentially the same thing as gears. That explains a lot. I don't agree with you, but at least I understand where you are coming from.
