I hope no one takes this the wrong way, but why are so many of the posters in the 50+ forum so old? Complaining about aches and pains, buying cruiser or hybrid bikes, and "bragging" about riding 5 miles, 2 or 3 times a week?
I'll be 60 next month and commute 4-5 days a week (only 8.5 miles one way ) and ride my road bike Saturday and Sunday.
Come on. Get out and ride and grab hold of life. You're not dead yet!
