PURPOSE: A motor for electric bicycle is provided to improve assembly accuracy by regularly managing concentricity and gear backlash value between a linear gear and a planetary gear. CONSTITUTION: A fixed axis(22) is fixed in the center of a hub housing(11). A motor(20) is installed in the hub housing. The motor is coaxially arranged to the fixed axis. A rotary shaft outputs the rotary power of the motor. The linear gear is connected to the rotary shaft. |
