The invention discloses an electrically-driven wheel body with a built-in battery and used for a portable electric bicycle. According to the electrically-driven wheel body, built-in stator bodies of a wheel integrated drive motor for a two-wheel electric bicycle or three-wheel electric bicycle are set to be a circular inner cavity configuration body in a flat circular box body shape and of a circular inner cavity structure with center machine shafts at the two side ends, a flat circular box body battery box is fixedly assembled into the circular inner cavity space, and the inner cavity space is fixedly and densely provided with a proper number of high-capacitance chargeable lithium cores in an embedded mode, and thus a main body structure is formed. According to the electrically-driven wheel body, sliding shaft sleeve holes in threaded screw pipe wall joint faces of sliding shaft sleeve hole portions for installing and fixing the machine shafts, a sleeve structure, a friction braking disc assembled to the shaft face of the machine shaft on one side in a sliding friction mode and the end wall face on one side of a shell rotor body of the wheel motor form a manual caliper brake friction disc braking and rotating stopping mechanism. By means of the electrically-driven wheel body, an external vehicle-mounted battery box body for a conventional electric bicycle is omitted, and thus the weight of an electric bicycle body is reduced.
