4971 miles (8,000 km), simultaneously with the chain
● Brake pad replacement: when its thickness is less than 0.5 mm
● Brake disc replacement: when the braking surface of the disc is less than 1.5mm thick
● Vehicle bearing replacement: abnormal sound and loosening
● Tire replacement: less than 2/3 of the tread depth of a new tire
Stay safe during inspection
1. Park the vehicle in an open and flat location.
2. Conduct the inspection in a safe place, and pay attention to the surrounding environment and conditions.
3. If any abnormality is found during inspection, troubleshoot before riding the vehicle. If you cannot
eliminate the abnormality, contact the after-sales service personnel or authorized service center.
* NOTE
1. Both the front and rear brakes are of disc type. Replace the friction plate of the brake in case of serious
wear.
2. Always keep the disc brake system clean. Remove any mud, debris, or oil contamination.
Check operating parts
1. Shock absorber inspection for bending, deformation and damage
Check the front shock absorber for damage, loosening, oil leakage and other faults. Shake the handlebar
and check for abnormal sounds arising from the failure of the front shock absorber. If the front shock
absorber produces an abnormal sound, contact the after-sales service personnel or authorized
service center.
2. Brake inspection
Check whether the free play of the brake handle is within the specified range (15–30 mm). If it's not,
adjust to the correct range.
3. Braking inspection
Run the vehicle on a dry and flat road. Apply the front and rear brakes separately, and check their
braking effectiveness.
4. Tire and wheel inspection
The tires are always exposed to the ground, so they may be damaged by stones, glass, nails, and other
foreign objects Avoid riding in places where the tires may be damaged. In addition, regularly check the
tires for damage such as obvious cracks, penetration of foreign objects (e.g. stones and glass) and
unreasonably abnormal wear.
1) When the tires are cool, check the tire pressure with a tire pressure gauge.
2) Check the tires for cracks, damage, foreign objects and abnormal wear.
3) Check the rims and spokes for loosening.
4) Check the chain tension. Chains should have a 0.4–0.8 inch (10–20 mm) moving range.
5) Check the tread depth.
Replace the tires if there is less than 2/3 of the original tread depth. In the case of abnormal sound and
shaking during running, contact the after-sales service personnel or authorized service center for
inspection and repair.
The recommended torque is 30 N·m for the central axle and 40 N·m for the rear axle nut. The tightening
torque of the front axle depends on the front fork.
* NOTE
1. The belt tension has been adjusted and tested by the manufacturer before delivery.
Do not adjust by yourself.
2. Firmly hold the brake lever. If the ideal braking effect cannot be achieved, check the cleanliness of the
disc. If this solution still fails, contact the after-sales service personnel or authorized service center.
Battery inspection
1. Power inspection
Check the battery as follows: charge it fully and measure the voltage of the anode and cathode of the
discharge port via a multimeter. The measured voltage should be 58-58.8 V (X160) and
66.5-67.2 V (X260).
2. Battery appearance inspection
Check the battery for damage. If the upper and lower seal covers of the battery are damaged, the battery
may be exposed to water in the case of seal failure. Contact the after-sales service personnel or
authorized service center.
