The NIU kick scooter uses both mechanical and electronic brakes.
If you’re experiencing issues with the brakes, please firstly check the mechanical brakes.
Hold the brake on one side and try to push the kick scooter forward. If you are easily able to move the kick scooter, the brakes are not properly working. You should adjust the brake cable fastening position in order to adjust the brake tension.
If, after adjusting the mechanical brakes, the brakes are still faulty, the problem most likely is caused by the electronic brakes. In that case, please contact after-sales service for repair.
