An electric device suitable for a bicycle is disclosed. Said electric pedal device includes a housing (10) configured to form a space therein, a rotating shaft (20) passes through both ends of the housing, a reduction gear set (30) configured to reduce a rotational force of the rotating shaft, a rotor (40) configured to rotate by an output of the reduction gear set, a stator (50) including a winding around core laminations (120) and a hub (100). Wherein said core laminations are coupled to the hub while prevented by a structure that an axial deviation relative to the hub is possible. Further a print circuit board (60), controlling the electric power to the stator, is fixed to said housing.
