Propulsion unit (8) for an electric, pedal-assisted bicycle comprising an electric machine (12) having a stator (14) and a rotor (16), rotatable about a motor axis (M-M), said rotor (16) being operatively connected to a crank pin (18), defining a crank axis (X-X), mechanically connected to pedals (20), and coaxial with the motor axis (M-M), wherein the rotor (16) is coaxial and external with respect to the stator (14) so-as radially enclose the rotor (16). The propulsion unit (8) comprises at least one electronic unit (32) for operating and controlling the functioning of the electric machine (12), and at least a pair of housings (24, 26) that define a containment space (28) which houses the electric machine (12) and at least partially the crank pin (18). The propulsion unit (8) comprises transmission means (36) of. the movement from the rotor (16) to the crank pin (18), said transmission means (36) being arranged in an asymmetrical position overall and decentralised from the crank axis (X-X) so as to be outside the projection of the rotor on a projection plane perpendicular to the crank axis (X-X).
