The invention discloses an electric-driven vehicle wheel body with a built-in two-gear mechanical speed changing mechanism. According to the electric-driven vehicle wheel body with the built-in two-gear mechanical speed changing mechanism, a speed changing gear box body which consists of two center crankshaft gear discs and two groups of sliding shaft gear discs is additionally arranged in a circular inner cavity space of a built-in stator body of a motor-in-wheel, wherein each group of the sliding shaft gear discs comprises four sliding shaft gear discs; the four sliding shaft gear discs of each group and the peripheral wall surface of the built-in stator body form a wheel tooth junction surface coaxial torque rotary transmission fit structural relationship; an outer shell rotor body is positioned at a low-speed normal-torque gear or a high-speed normal-torque gear or a non-driving idle gear to adapt to different driving conditions by controlling the axial positions of a dual-layer knob sliding sleeve crankshaft and a crankshaft wheel disc body manually or electrically. By using the electric-driven vehicle wheel body with the built-in two-gear mechanical speed changing mechanism, the space position of a vehicle frame of a conventional vehicle body driving machine can be omitted, so that the comfort and the practicability of a passenger compartment are improved.
