An electric-bike hub motor comprises a horizontally arranged spindle (1), a hub shell (2) that is rotatably mounted outside the spindle (1), a stator (3) and a rotor (4) that are arranged inside the hub shell (2), and a gear speed reduction mechanism. The stator (3) secured on the spindle (1). The gear speed reduction mechanism comprises a rotor gear (5) that is secured to the rotor (4) and arranged coaxially outside the spindle (1), a planetary carrier (6) that is secured on the spindle (1), a planetary shaft (7) that goes rotatably through the planetary carrier (6). The left planetary gear (8) and a right planetary gear (9) that are secured on the planetary shaft (7), and a sun gear (10) that is secured to the hub shell (2) and arranged coaxially outside the spindle (1), wherein the left planetary gear (8) engages with the rotor gear (5), and the right planetary gear (9) engages with the sun gear (10). The electric-bike hub motor means has a large output torque and internal transmission function.
