A test ride for a new bicycle Update... What should I actually do on the test drive? The LBS has been kind enough to allow me to try out a brand new bicycle. 

What things should I consider when test riding bikes that I am considering for purchase at a LBS? And what should my procedure be while on the test ride? Also plan to test ride between 2 - 5 similarly priced bikes.  

This will be a hybrid (urban) bike intended for daily commuting. The LBS will do some minimal adjustments prior to the test ride, so how do I determine if it's a good/bad selection vs needing customized adjustments/fitting?
This goes against accepted wisdom, but I think test rides are overrated. Not useless, but overrated. 

You're going to own the bike for a long time presumably. You're going to be able to play with the tire pressure, the handlebar position, the seat height and fore/aft, the seat itself, the pedals, the cranks. As you develop cycling muscles, your position on the bike might change a little. If the frame size is "close enough", all of these things can be adjusted to lock it in once you get riding it. 

I could give you the same bike with different tire pressures and you would say, "wow, that one was a comfortable ride" or "wow, that was a fast ride". You get it home, change the tire pressure, and all of a sudden it feels like a different bike.  

Like sillyyak said. . .some of the important stuff for you is going to be standover height, weight, ability to accessorize. And almost none of that is learned on an actual test ride. 

As long as price and model are similar, I think it's a good idea to get a bike at the most convenient shop, or the shop where you like the people the most -- you will be going back there (repairs, clothing, helmet, lights, accessories, etc). I wouldn't rule out a test ride, but just don't use it as the deciding factor. The things a test ride reveals are not necessarily the things that matter in the long run, and can even be deceptive. 

Let use know what you end up getting.
