Benefits of a mid drive motor compared to a cheaper hub motor:

  • Uses the bikes gears as the engines transmission so the motor can run at the optimum RPM range
  • Increased performance
  • More efficient
  • Better at climbing hills
  • Better weight distribution as the motor is positioned close to the center of gravity and low to the ground
  • Improved handling
  • Easier maintenance and installation
  • A Mid Drive ebike is easier to ride because the extra weight on the wheels of a hub ebike make it tougher to pedal

    36/500 Mid Drive

    Posted by Richard on 11th Apr 2018

    Initially experienced difficulty installing the motor, a very tight fit required 5-6 attempts while twisting etc. A good thing in the long run. Fantastic unit to operate, a lot of torque, great control system. Can be touchy at very low riding speed, gently ride a brake to do a tight u-turn. Learning to match derailleur 8-speed gear selection with unit's power/speed selection to give correct pedalling speed.
