A wheel assembly (1) for a vehicle, uncommonly capable of a compact construction and ease of maintenance, comprises: A wheel rim (2) suitable to rotate around an axis of rotation (a-a), defining an axial direction (A-A) parallel or coincident with said axis of rotation (a-a), an orthogonal radial direction (R-R), and a circumferential direction locally coincident with a tangential direction (T-T) orthogonal to the axial direction (A-A) and the radial direction (R-R), said wheel rim (2) having a radially outer side, or outer side (3), opposite the axis of rotation (a-a), and a radially inner side, or inner side (4), facing the axis of rotation (a-a), said rim being suitable to receive externally a tyre (5), and wherein said wheel rim forms internally a cylindrical chamber of the rim (54) delimited radially from said inner side (4); a motor (306) comprising a rotor (307) and a stator (308); said rotor (307) being supported, free to rotate, on said stator (308); said stator being fixed to a stator support (120); said motor (306) being housed in the said cylindrical wheel rim chamber (54) of said wheel rim (2); said rotor (307) is selectively, removably and rigidly connected to the inner side (4) of said wheel rim (2), avoiding the interposition of elastic members or damping members; said assembly (1) also comprising a braking device (10), said device comprising a disc brake disc (11) having a radially outer edge (12) and a radially inner edge (13), said braking device (10) further comprising a disc brake caliper (14) selectively, removably and rigidly connected, directly or indirectly, to said stator support (120), said disk brake caliper (14) being placed with its active part (21) astride the inner edge (13) of said disc brake disc (ID; in which—said wheel rim (2) is made in two parts (15, 16) selectively and removably connected with each other to form a wheel rim body (17); and wherein—one of the two parts of said wheel rim (15) forms in a single piece at least one spoke (18) that protrudes radially towards the axis of rotation (a-a); and wherein—said disc (11) is connected with its outer edge (12) to said at least one spoke (18).
