FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to electric drive for bicycle. Electric bicycle drive comprises electrically connected power source, control unit and motor including rotor in the form of disc with central hole and permanent magnets arranged on periphery and a stator formed by windings arranged in the housing and interacting with constant magnets of the rotor. Rotor disk is rigidly fixed on the axial bushing and is placed inside the stator casing mounted on this axial bushing by means of bearings. Axial bushing is installed with possibility of joint rotation on bushing of rear wheel of bicycle in section intended for arrangement of sprockets unit.
EFFECT: improved drive reliability is achieved.
