I am older than you and was out of shape when my wife and I bought bikes in 2020. I bought the Roll Elite. I liked it and rode it a lot. I put clipless pedals on it, got on Strava, bought a Garmin, and got fitter quick. I then bought an endurance bike and never looked back. I still have the Roll Elite but don't ride it. I am glad i bought it but in hindsight I probably should have went directly to an endurance or road bike because I know I am competitive, And love speed.
