I don't ride a regular bike so I am about 3500 km's ahead of myself in comparison.
I'm not an athlete in training trying to get my burn on so the bike gives me exercise just like walking or jogging depending on how I feel.
~5-6 x's a week of 1.5hrs at least. (30 - 70km each day). Ya multiple charges on days.
It makes my muscles sore and my shape is toning.
I've gone 45 x's to work via ebike since August 2016 last year which beats the exercise I get when I'm in my car... It's usually the most enjoyable part of my day.
I get a lot of hi intensity interval training in by accident when I'm going downhill.
I spend more time on the bike because if I need to phone it in I can. Sometimes getting out is half the battle.
It's a pretty cheap date if you have two!
The destination no longer matters.
I have an ongoing competition to see if I can keep ahead of the boyfriend in miles on the odo.
So I go out for fun, errands, work or just because. It has amplified my exercise to a great degree how much is hard to say.
I'd say it is going to be a contributing factor to my overall health and well being for years to come if we stay on the current path. (Injuries and crashes not included
