The invention discloses an automatic lifting supporting device for an electric bicycle. The automatic lifting supporting device comprises a main rod, a sliding sleeve, a fixed sleeve, a manual hydraulic device, an automatic hydraulic device, struts and ratchet wheels, wherein the main rod is fixed to the position below a seat of the electric bicycle; the fixed sleeve is arranged on the rear portion of the main rod and connected with the tail end of a hydraulic cylinder of the manual hydraulic device and the tail end of a hydraulic cylinder of the automatic hydraulic device; the sliding sleeve is arranged on the front portion of the main rod and connected with a hydraulic rod of the manual hydraulic device and the upper end of one strut; the ratchet wheels are fixed to the lower ends of the corresponding struts. The automatic hydraulic device pushes the corresponding hydraulic rod which pushes the corresponding strut to drive the wheels in linkage to move forwards and downwards, and the ratchet wheels are supported by the ground when arriving in place to keep balance of the bicycle; the automatic hydraulic device takes back the corresponding hydraulic rod or the manual hydraulic device pushes the corresponding hydraulic rod, the hydraulic rods drive the struts to drive the ratchet wheels in linkage to move backwards and upwards, and the ratchet wheels return to original positions. The automatic lifting supporting device is reasonable in structure, can support the electric bicycle, reduces the frequency of making the legs of a driver supported by the ground, and improves safety.
