After 4 decades and 40 pounds lost I decided at the suggestion of my Dr to start riding. It was explained to me not to purchase from a big box store and get fitted for a bike by a local shop. After many, many questions it was suggested to purchase a Townie 21p based on a short inseam (29") and being a more comfortable bike to ride as a beginner. I will admit that I've been out only 3 times in the last 2 weeks for a total of 45 miles. But they sure have been enjoyable miles so far. So much so that's what keeps me motivated up to this point. I'm not out to break any land speed records as I average between 8-10mph. I do feel a little burn in my thighs & back but it's a good feeling. I really wished I would have started this 30 years ago. I've taken a break for a couple of days to allow my body to heal a bit. I can't relate to any other bike but the one I have but I can say that for being out of shape & needing to shave off another 30 pounds I'm glad I had a bicycle pro set me up with what felt would work in my condition. On a side note another motivation for me was to get passed up by a gentleman yesterday with a bike with a trailer with 2 forty pound bags of salt. And he passed me up as if I wasn't even moving. I was in awe!
