I agree it makes the internal "I'm to tired to ride to work today" argument harder to win. I burn about 1/3 less calories on the commute but save almost an hour a day. I make it it up by taking the road bike on weekend group rides that are fun again because I'm not worn down from the weekday commutes.

I've used power meter pedals to compare my input riding an e-bike to road bike and for me it has been the same just shorter time. Unless it's one of the times where I've forgotten to fully charge the battery and I'm conserving battery power I am just going faster and working about the same.

Most roadies who haven't ridden and ebike assume they are all 3000 watt souped up throttle controled mopeds because that's what you see on youtube. One shop had a video bragging about their 45 mph conversion blasting down a mup for demonstration.
