As a 220#, 60+ guy, I ride a steel framed touring bike. for me, its exercise and load capacity. Its my daily commuter and I like to be able to haul my lunch, work clothes, and stop for a sixxer and have room to carry it home. In city riding I average 13mph. it works.
I would never advocate this bike for you. I have been riding for transportation for nearly 20 years. If, on a rare occasion, I need to trail ride, I have an old RockHopper c.1995, for faster road riding a Jamis cross bike with street rubber. No one bike will be the be all, end all. I would have 20 bikes if I had room and my wife wouldn't turn purple in the face. Get any bike that seems right, it will be a good place to start, but be careful. It may not be your only bike for long.
