I'll be 80 in December, I ride an old beater road bike 3-4 days a week, mostly 5-6 miles, sometimes as much as 10-12.
Last week I learned an important lesson: Get yourself a couple of pair of bike shorts and wear them when biking. Bike shorts are made with inner shorts and outer shorts. The inner shorts have a nice, big, pad that gives you a soft place to sit as well as keeping your personal parts padded and protected. I wish I had discovered bike shorts years ago!!
I bought three pair of NEPEST Men's MTB Mountain Bike shorts.
