When I watched the Tour de France on OLN, every rider gave a hands in the air victory salute when winning a stage, and I often see them ride with no hands when eating or zipping up a jersey. When I try to ride no-handed on my bikes, even for a second, the front end feels like it wants to go left or right. Is it technique that makes a difference or is it something about the bike set-up? When I was a kid it seemed easy to ride no-handed on our clunky 30 lb. bikes.
I find that I can ride no handed easily on my road bike and commuter bike, but the tri bike tends to wobble quite a bit. I figured it was the aero bars on the front.
I echo some of the other comments, it seems largely to do with the bicycle involved, more than the rider. My “tri” bikes will not allow “look ma, no hands” riding, but my main training/road bike does easily. In fact, I can climb no handed down to about 10mph. However, put aero bars on that bike and forget about it, no way.
The trick is to lean back and have an upright posture as well as going fast. I can ride no hand on any TT or road bike I tried. The only bike I can’t ride with no hand is my Brompton.
I have wrote a review of the Brompton some time ago:
