Greetings, I am 55 Y/O and learned how to ride a bicycle August 10. I know the day well, brought the bike home and practices until I could ride. Fearful of falling I bought a Townie 3, where I can put both feet on the ground when sitting (semi-recumbent). After reading all the miles you guys put on I feel ashamed riding my 3 miles a day, but it takes me 20 minutes. I have been riding every day after work. I know that in a month I will be doing 10 miles easily. Hoping to lose 50 lbs, I do other exercise as well.
