Before I moved, I used to commute on my regular bike (11 mi each way)
Now I moved and I have a 18.5 mi commute. With the ebike, I can do it under an hour each way, and when it's 100° F outside, I come home only a little bit wiped out, no more well-done slouch.
No throttle, just a more sane way to commute without using my car. Still get much needed exercise. And it fits in my office.
