Following a heart attack, I got a pedal assist, I got hundreds of hours of exercise and outdoors. You always are exercising, just lightly, and you can adjust your input level upwards at will. Brake fluid issues got me back onto my push bike this week. It's different - there's definitely more effective strength training going on in accelerating and climbing hills. Otherwise, it's not THAT much of a difference. I just go slower. 10 mph rather than ~15.
