I'm a physical therapist, and a bit of a fitness junkie (occupational hazard) but just got into cycling (with a real bike!) about a year ago. I'm pleasantly surprised at how all the new technology, from seats to shorts to shifters, makes riding so much more enjoyable than when I last rode in college for transportation! I'm really excited about cycling as a sport I can age with. It's been great to discover this community w/ all the great expertise.
