Propulsion unit for an electric, pedal-assisted bicycle comprising an electric machine having a stator and a rotor, rotatable about a motor axis, said rotor being operatively connected to a crank pin, defining a crank axis, mechanically connected to pedals, and coaxial with the motor axis, wherein the rotor is coaxial and external with respect to the stator so as radially enclose the rotor. The propulsion unit comprises at least one electronic unit for operating and controlling the functioning of the electric machine, and at least a pair of housings that define a containment space which houses the electric machine and at least partially the crank pin.

Propulsion unit for an electric pedal-assisted cycle and pedal-assisted cycle thereof

Propulsion unit for an electric pedal assisted cycle (EPAC) comprising an electric machine having a stator and a rotor, rotatable about a motor axis, said rotor () being operatively connected to a crank pin, defining a crank axis, mechanically connected to the pedals, wherein the propulsion unit comprises at least an electronic unit for operating and controlling the functioning of the electric machine, wherein the propulsion unit comprises at least a pair of housings defining a containment space which houses the electric machine and at least partially the crank pin, wherein the propulsion unit comprises transmission means of the motion from the rotor to the crank pin, wherein the electronic unit is contained and supported inside said containment space by an intermediate support element.
