Electric bikes aren't for me yet, I still like to push on the pedals. However, I was around several this summer on different rides. It is pretty amazing the power that they have, 750 watts is a lot. I got passed a couple times by old folks going uphill, I'm pushing the pedals relatively hard and they are barely pedaling. Range is unknown, never saw how far one went. Downside I will say is the weight....60 pounds is ridiculously heavy. I would not want to pedal that thing once the batter dies. I don't have a high end mtn. bike and it weighs about 30, could not imagine twice that from both a pedaling and handling perspective. Gotta be a pig. But certainly some merit in their use, stealthy and can cover some ground.
