Hi, I am also a senior biker, age 60. My son encouraged me to start riding about 5 years ago and I am now on my second mountain bike and my second road bike (both upgrades I felt I deserved!!). I am much more fit, more healthy, and much more enthusiastic about life (even tho I ski all winter as well). I just returned from a 2-week bike tour in New Zealand. More power to us!!
