FWIW, I commute on a bike that's not too far removed from the Dr. Good. It came stock with 32mm tires and I am looking forward to the Spring when I can get back on them; I am currently running 35mm studded tires. Both sets support my almost 300 lb. frame just fine. I also use an IGH and I love it. It really shines in inclement weather. To me the Dr. Good looks like a great value. You could slap on some fenders, a rack, and some battery-powered lights for around $100, and decide if you want to upgrade to a dynohub later.
