How does the motor work with the mechanical gears of the electric bike?Updated 2 years ago

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; this is what allows your e-bike's pedal-assist system (PAS) to translate your pedaling power into motor assistance. 

Using the correct mechanical gears during your ride is important since your PAS will move your e-bike quickly and powerfully, exacerbating the effect of incorrect gear selection. 

Take care to avoid cross-chaining as you shift into the right gears, too. For more on cross-chaining, see our Magnum Academy article, Dropped Chain On E-Bikes: Causes, Fixes, And Prevention.
