System for improving the pedalling performance in bicycles, for which purpose the rotation of the pedal 3 and of the connecting rod 5 corresponding to each leg is connected in such a manner that, to each angular position of the connecting rod 5, there corresponds a single angular position of the pedal 3, the connection between the angles of said connecting rod and pedal being adjustable as desired. The system makes it possible to improve the orientation of the cyclist's foot during pedalling. <IMAGE>
