3. Key components such as the handlebar, folding column tube, seat, seat tube, front and rear axles, central axles, cranks, and front and rear tires should be inspected and adjusted frequently to ensure transmission parts are flexible and show no anomalies. Loose nuts and bolts should be tightened promptly.
4. It is recommended to lubricate parts (e.g., front axle bearings, central axle bearings, rear axle bearings, forks, pedal bearings, etc.) every six months with calcium-based grease (lubricating paste). Every two months, add 30# oil to the chain, gear shift cable, foot support, and other parts.
5. If wear parts are found to be damaged, such as brake pads, chains, tires, etc., you can seek a local repair point to replace them, but be careful to replace them with parts of the same type and specification.

Motor Maintenance

1. Do not open the motor base and end cover after sealing treatment.
2. The motor must be kept clean. No foreign matter, corrosive liquid, or gas should enter the motor. The motor casing should not be hit or cooked to avoid motor damage.
3. The motor's waterproof rating is IPX5. Do not wash the motor with a water gun or allow it to be submerged in water. If the water level reaches the center of the motor hub, it may cause a short circuit in the internal wiring of the entire vehicle and damage the electrical components.

Battery Maintenance

1. Lithium batteries have high capacity, long life, and are lightweight. Their lifespan is closely related to how they are used. Do not wait until the power is insufficient to charge them, and do not store them for extended periods. It is important to develop a habit of diligent charging.
2. The initial charge must be full. It is recommended to charge for 6 to 8 hours each time, but no more than 12 hours.
3. When not in use for a long period, the lithium battery needs to be charged for more than two hours per month. Storing the battery in a low-power state is strictly prohibited. If the battery voltage reaches a deficit state, it will cause significant damage to the battery and it cannot be recovered, resulting in battery damage.

Danger: Do not disassemble old batteries without authorization; they must be recycled according to local government designated locations or our special maintenance points.

Warning: The battery should not be placed near open flames or high-temperature heat sources, should not be thrown into fire, and should not be exposed to the sun in hot weather.
