Abstract

There are disclosed new bicycles urging -via four new additional gears at the rear gear- the chain in tracing a semicircle the radius of which is equal to the radius R of the front gear. The four auxiliary gears in question are similar to the rear gear of the bicycle and encountered along with their rotation shafts on a homocentric circumference of R-r radius of a circular metal plate (where R is the radius of the metal late and r the radius of the auxiliary gear). In general, in all bicycles the developed friction is: a) analogous to the cyclist's weight; b) inversely analogous to the radius of the rear gear and c) inversely analogous to the radius of the semicircle traced by the chain at the rear gear, what constitutes the object of the invention.
