I'm 62 and I often do it just to be able to sit up and shake out my hands. I have even removed a rain cape but I stopped doing that when I realised that for as long as you are taking to free one hand from the cuff, your hands are locked out of reach of the bars!
I think it's to do with speed and hence gyroscopic action keeping the front wheel on a steady line because I can't ride no-handed at slow speeds. Don't forget also that in olden days bikes had much heavier wheels, longer wheelbases and more caster, making them far more stable than today's finely-tuned machines.
Hi Globalti. I have a funny feeling that you are correct here and it is more about speed than anything else but I am not so sure about the longer wheelbases nor the heavier wheels either.
How do you account for the professional riders of today riding with apparent ease and performing gymnastis including the removal and refitting of their various items of gear. They are riding bikes that are so light that they often beggar belief.
I am relating back to the late 50's/early 60's when I had my 1937 Hetchins Curly track frame and rode fixed wheel for many years before having the rear stays widened and Campagnolo road dropouts inserted to take a a five speed block with a double Stronglight up front.
I also rode very lightweight wheels (Asp rims and Tubulars) with Aerolite large flange hubs.
The wheels on both my bikes are Mavic Aksium Race on Mavic Cartridge Hubs with bladed spokes - so in real terms little has change as far as weight goes.
I have even tried moving the saddles back a touch on their rails but that did not improve matters at all. Indeed the Hetchins complete with the oversize cape roll and spare tubular (of the period) rode perfectly balanced when being ridden with no hands.
