An electric power-assist device for a bicycle includes an electrical machine with a rotor, a connector structured to attach to the electrical machine, a drive pinion arranged to be driven by the rotor of the electrical machine, and a supporting structure. The drive pinion is structured to mesh tangentially with a complementary toothing integral to a tyre of a rear wheel of the bicycle. The connector is borne by the supporting structure. The connector together with the electrical machine form a sub-assembly that is manually separatable from the supporting structure.
