I decided to get the Wowgo 3x to replace my crappy hub motor board from another brand which failed within the first month. Compared to my old board, the 3x is very well constructed and the components are of better quality.
The flexible deck feels very comfortable to ride and absorbs cracks and road vibrations well, I'm able to ride longer distances without feeling fatigued.
With the belt drive, acceleration and braking is very responsive. Having 4 full wheels feels so much better than thin hub sleeves, the softer and wider wheels feel much more comfortable and provides better grip.
Overall, I feel much more confident on this board than my old one. I'm able to go further, ride at higher speed while feeling more stable, and brake with more confidence at intersections.
