I have a very vague recollection of having read an article on a VMX/Vinduro bike, quite possibly a European factory prototype of the 1970/80s, that had a novel kick lever.
Instead of having a pivot at the base or at the top, the main shaft had a cross hole at the top and the foot pedal would slide in/out perpendicular to the center plane of the bike as needed, with a detent holding it in position.
I've looked though some of my books that have a lot of period photos but I can't spot anything like that and my memory which is usually pretty good for odd bits of trivia is failing me on this.
Does this strike a familiar chord for anyone?
cheers,
Michael
