Abstract
Un cambio elettromeccanico (10) per bicicletta comprende un motore elettrico (16) comandante, attraverso un primo cinematismo rigido (29) il movimento di un primo elemento (28) collegato, attraverso mezzi cedevoli precaricati (24, 25), ad un secondo elemento (21) di movimentazione, attraverso un ulteriore cinematismo rigido (18, 19, 20) di un organo deragliatore (11) mobile per innestare una catena (12) di trasmissione in corrispondenza di un prestabilito pignone di una pluralità di pignoni (13) coassiali e di differente diametro.
