You don’t even have to be old. Ebikes are car replacements and can tow children, groceries, and furniture with ease. They flatten hills, get you to work on time and without sweat, and significantly extend the realistic travel radius around your home/work/last transit stop. Expect to pay pennies to recharge it, rather than two or three figures for a full tank of gas.

Any fitness benefits you get are just a cherry on top. Ebikes just make it so much easier to skip the car trips in your village or city.
