I'm coming back from injury and it's getting me back out again most days, I really enjoy it. However I do want to get back onto a "proper bike" as soon as possible. Its very hilly where I live and its been great to get back out.
A week and a half after coming out of hospital after major abdominal surgery, I was riding mine. I could barely walk 200 yards, and was still getting home visits from a community nurse but I was cycling 8-10 miles on my ebike. Since the surgery, it has become a staple part of my transport. I use it for commuting and picking up the shopping and firewood, but for recreation I use a normal bike.
There's a guy I go out mountain biking with. Pushing 70, but due to a motorcross background - absolutely fearless and highly skilled. He had one of his lungs removed a while back, and an ebike keeps him riding.
