Abstract
The invention concerns an electromechanical device for the rear transmission of a bicycle making use of a pedal crank from the central movement and via a control cable 10 which can be wound and unwound on a drum 54. This drum is actuated by a sprocket wheel 49, turning in stick-slip motion in one direction or the other by means of two thrust teeth 13, 14 which are activated under the control of an electromagnet 34 and which receive motion from means capable of transforming the rotary motion of the pedal crank into an alternating motion of the teeth themselves. <IMAGE>
