Abstract
A power operated gear change assembly for bicycles, which includes a gear change whose derailleur is displaceable by an electric geared motor and associated power supply accumulator, operated through a manual control device or detector for detecting the derailleur displacement, and a control circuit for controlling operation of the electric geared motor. The electric geared motor is directly fitted on the derailleur of the gear change, and the detector includes a transducer device placed in a remote position relative to the derailleur of the gear change and operatively connected thereto through a transmission device. The electric accumulator is rechargeable by means of a dynamo-electric unit incorporated in the derailleur of the gear change.
