Does the motor work with the mechanical gears of the Electric Bicycle?

Your Magnum E-bike comes with a rear hub geared motor. The motor has its own internal planetary gear transmission. The mechanical gears on your E-bike are externally attached to the motor wheel and allow you to pedal thereby assisting your E-bike. Using the correct mechanical gears is important since when pedaling the motor is assisted and will work quicker and more powerfully.
