57 1/2 here. I've commuted to work for a little over a year now, 30 miles each way, I ride it one way 4-6 times a week when the weather is decent-too far and roads too busy to ride in the rain or snow. My goal is to ride both ways on the same day more times than last year (10 times). I'm amazed sometimes that I am almost 60, when I'm riding I still feel like a kid.
