Been years since I have ridden a bike (actually more like 9) I used to make the whole commute to work (3 miles in and 3 miles back) with no hands minus when I had to stop for traffic or make a very technical turn.

Im still out trying bikes to choose wich one I want to buy and the Gary Fisher Kaitai I was able to ride handless all around the parking lot of the LBS with no trouble even after being off a bike for 9 years. The Rockhopper I could do no hands but not with the incredible and seamless balance of the kaitai.

I just like to relax and go handless somtimes, also if you have a big lean on your bike it may help you ease up the back and get some blood flowing.

You should see us in the Marines some of us even RUN with no hands... just watch them run with there arms flailing around like they are paralized... it saves energy but to me the loss in balance isnt worth it.
