The thing is, a bike need not be an exercise machine, although that is the message that our culture provides, A bike can also be a labor saving device. We can use a bike to arrive at our destination with much less effort and perspiration than if we walked. I ride at about the speed of a jogger and it works fine. In 1957, when I started cycling was transportation, not exercise, and bike costumes were not even imagined. Ebikes may be a solution for you -- allowing you to ride with the same effort as walking, yet travel at the same speed as the sporty people on road bikes.
