Frequently Asked Questions
XT5 Ultra Change Model

Solution

1. Please check whether the battery is fully charged.
2. Ensure the scooter is activated and the mode is switched to S mode.
3. Check the tire pressure and make sure the tires are inflated to the recommended levels (tubeless tires: 45 psi; inner/outer tube tires: 50 psi; refer to the actual markings on the tire).
4. Push the scooter and check whether the motor is stuck, the brakes are too tight, or the brake lever does not return properly.
5. Confirm whether the scooter can reach its maximum speed when coasting: lift the motor wheel and rotate it by hand to check if it spins freely or is stuck. If it spins freely, turn the motor wheel with force; when the dashboard speed exceeds 5 km/h, press the throttle to increase speed and check whether the scooter can reach its maximum speed.

Solution

1. Squeeze the brake lever several times and observe whether it returns to its normal position. If it does not, replace the brake lever.
2. Check whether the rear light responds when the brake is squeezed. If there is no change, the brake signal is not being triggered, and the brake lever needs to be replaced.
3. After fully squeezing the brake, push the scooter forward. The front wheel should be locked. If the front wheel can still rotate, the mechanical brake force is insufficient and the brakes need to be adjusted.

Solution

1. If the handlebar is wobbling, check whether the screws securing the headset are loose and tighten them using a 3 mm Allen wrench.

Solution

1. Check whether the screws at the base of the stem are loose and tighten them using a 5 mm Allen wrench to reduce stem wobbling.
2. Check whether the flat-head screws on the stem are loose and tighten them using an adjustable wrench.
