Motor
Unlike a traditional motor in the front or rear wheel, Norta exclusively mounts center motors. These ensure that power is transmitted directly to the bottom bracket, which enhances the natural riding sensation. Due to its location at the bottom of the frame, this type of motor provides a lower center of gravity and thus higher stability. A center motor is compatible with any type of gearing so you can configure this bike entirely to your own preferences.
