Love the Dr Good!
I am about 210#, so my weight is not a factor in my decision to get this bike. I had been looking for a city commuter that was modeled after a Dutch commuter in terms of riding position, comfort, durability and low maintenance componentry. The purpose of this bike was to replace my car. I live in an urban area and for those amenities that are not in walking distance, nearly all are in biking distance, including work.
I have had the bike since April 1, 2011 and I ride it every day. I outfitted it with leather grips (the kind that support the wrist), fenders and a rack. The Dr Goodis the most comfortable bike I have ever ridden when it comes to a sweet-spot riding position (and I have been cycling with road, dirt and mountain bikes my entire life... this is my first dutch-inspired commuter). Better yet, it performs WAY better than I was expecting my first dutch commuter to perform.
You need to have the proper expectations for this bike. 1. it is heavy, as nearly every internal drive hub bikes are. 2. It is not designed for touring, it is designed for slamming through the city. 3. Its not a racer. 4. its not built for off roading, not even a little.
I wanted a commuter that was:
-Comfortable, relaxed seated riding position that allowed me to see above car rooftops.
-7-8 speed internal gear hub = low maintenance and extremely durable.
-Drum or disc brakes.
-relatively good performing for the style ( I was completely willing to sacrifice some performance for comfort)
My expectations as I was shopping:
-this will be a heavy bike
-this will not be a fast bike
-this bike will probably be loosey-goosey
-this bike will have the grandpa or "opa" look
-this will be a comfortable bike
-this will be a durable, low maintenance bike.
When I first got on the Dr Good, I was amazed. From the first down-strike on the crank, I could tell that this bike wanted to go. For such a comfortable, ass-heavy bike, it was tight and felt very efficient (keep in mind my expectations). It didn't look like the grandpa bike I was expecting to buy, and I was reluctant to even take it out for a spin at the shop because of that. Boy am I glad I did. I never realized that such a comfortable, leisurely riding position could be found in such a fun and responsive bike.
As another poster noted, I can easily get into the low 20s mph on this thing and I feel very comfortable with avg speeds at 15-18 over my 10 mile commute in a very relaxed position. When I need a burst of speed, I can stand up and really crank on it- and it goes! I can hang with touring cyclists for a decent amount of time, but they will wear me out after a while. Up hills, especially. But, down hills - watch out!
My advice with the Dr Good is make sure you get the sweep back bars. It comes with either the sweep back or the straight. Straight bars to me are not a good option for any commuter. They make you lean forward more and put more of your weight into your hands/wrists.
I say, if you are looking for a Dutch -inspired commuter, go for the Dr Good. The thing is bullet proof and a joy to ride at slow speeds or fast.
