above 0℃ (32°F) and the battery remaining capacity should be checked regularly.
Charging and Charger Usage
1.When charging, you are required to use the OEM charger. Do not use third-party charger, it
might damage the battery and cause serious injury.
2. Check if the input voltage of the charger is same with the voltage of the power supply.
3.When the battery is fully charged, the charger will automatically stop charging. Avoid

In principle, the first inspection (also known as the first maintenance) can be done at
10-30km if ride normally.
Check Parts
1. The tightness of the spokes on the rear wheel
2. If there is a gap in the headset
3. Check the tightness of chain
4.Belt tightness inspection. (There may be some friction on the new belt, which can be waxed
on both sides of the belt.)
5. Suspension adjustment. Check if there is oil leakage, and if the compression and rebound
damping is in the correct position.(Note: During adjustment, do not turn the adjusting knob
to the extreme position.)
6.Check the tightness of all screws on the handlebars.
WARNING：During the whole maintenance process, the bike
cannot be powered on, which means you cannot do mainte-
