The invention relates to a system (10) for the motorized assistance of a bicycle, characterized in that it comprises a support post (28) which comprises at least one arm (32a, 32b) extending from a base (34a, 34b) intended to be connected to a bicycle, as far as a free end forming a transverse locking finger (36) perpendicular to said arm (32a, 32b), and the system (10) comprising a removable drive unit (30) which is designed to be mounted on said post (28) and which comprises a cylindrical drive roller (42) powered by an electrical energy source and rotationally driven about a transverse drive axis (C), said drive roller (42) being intended to drive a wheel (14) of the bicycle by friction, rubbing against a tread of a tyre (46) with which said wheel (14) is fitted, a housing (48) for locking the unit (30) on the post (28), and a locking cleat (60) which is arranged inside the locking housing (48) and comprises a stop catch (66) intended to collaborate with the locking finger (36) belonging to the post (28) so as to lock the unit (30) on the post (28), and which delimits a bearing face (62) extending at a tangent to the drive roller (42), and in that the unit (30) is able to be driven, in a locking movement directed towards the base of the post (28) at a tangent to the drive roller (42), from a free position in which the unit (30) is detached from the post (28) into a service position in which the unit (30) is translationally immobilized along the arm (32a, 32b) of the post (28) in a first direction and in an opposite second direction, by, respectively, the locking finger (36) which is pressing against the stop catch (66) of the cleat (60), and the drive roller (42) which is pressing against the tyre (46), and in which the unit (30) is prevented from pivoting about a transverse axis embodied by the locking finger (36), in the direction of rotation of the drive roller (42), by the arm (32a, 32b) of the support post (28) which is bearing against said bearing face (62) provided for that purpose.
