In my younger days, I had cycled an inexpensive normal bicycle up and down East Coast Cycling Track up and down using only one leg and handsfree, from end to end 12 km in around 45 minutes, in training seen by many people. And it was done with people cycling up and down the cycling track, which I am able to avoid knocking onto them. Using a single speed, fixed gear bike.
Hope that one of these days, I can find some officials to video record and verify it, to submit it to the Guinness Book of World Records.http://awesomefeat-henry.blogspot.com/2007/02/marathon-one-leg-handfree-cycling-feats.html
It will be against great odds if I am able to gain entry into Guinness Book of World Records?
