Got back to biking about five years ago or so. I was in my early 60 years and just wanted to get some exercise in my daily routine. Jumped on my old mountain bike for fun. I started slowly and enjoyed it very much and decided I wanted a new bike. Things have improved exponentially since I last looked at bike technology in the '90s. Ended up with a CX bike to ride road and gravel. Been riding around 1k miles a year and having fun doing it all the while getting some pretty good exercising to boot. So its a win-win for us older 50+ folks.
So keep doing what you are doing and think about if you want a better bike in the future and how much more you want to get into this sport. There are many other things to keep us busy but I like this one the best (at least for today)...
