Serious question: If you have an ebike, how do you know how much energy you've used on a ride? I have a phone app that estimates calaries burned, etc. So, if I do my "one hour at 15mph" thing, now I could do that easily with an ebike, but how do I know how much of a workout I really got in relation to my current bike? For example, I've mentioned before that just getting a "nicer road bike" would not do anything to help my "exercise level" because the easier it goes faster, the less I have to work. So I can go faster/futher without getting more workout. And I'm thinking an ebike will be that up another whole level. I might do 1 hour at 20mph with an ebike and use less energy if I understand correctly how they work.
I really think my plan now is find one for Amy, that will allow her to ride fast enough that I'm getting a workout on my old bike. If I can get a workout and she can keep up with me, then we're killing 2 birds with one stone. If we both get one, it will just take the workout out of it for me, won't it?
