Hi, I do use an ebike for commuting, just started this spring. I went to the ebike because I pull a burley trailer with my daughter in it, and with an 11 mile commute and a lot of hills, I just couldn't manage it efficiently on a road bike. My feedback is this... it's a completely different riding experience. I'm finding I really enjoy it because I can zoom along at around 18-20 mph most of the way and arrive at work feeling like I've gotten some exercize but am not exhausted. That said, if I was in great shape from riding all the time anyway, and wasn't pulling a trailer with lots of hills and so on, I'd probably stick with the road bike. I guess the variables I'd look at are whether you really want a transportation alternative that gets you on a bike more often... saving gas, arriving at work with a smile, those kinds of quality of life things. Personally, I'm absolutely in love with my ebike; it's the answer to my commuting dilemma. Yes, ebikes will go as fast as you can pedal them. Most are fairly heavy I think (mine certainly is), so it's definitely not the same sensation as a road bike. It's funny, now when I go for a recreational ride on a road or mountain bike, I look longingly at the ebike, but once I'm pedaling, it's all fun...
