Note: The battery contains a small amount of charge from the factory. Fully charge the battery before the first use. Always use the original manufacturer's charger. Using non-original chargers may damage the battery.

Charging Process:

1. Charging: Insert the charger plug into the battery's charging interface and then plug the charger into the wall socket.
2. Status Indicator: A red light on the charger indicates charging, while a green light indicates the battery is fully charged.
3. Charging Time: Approximately 6-8 hours.

Important Safety Notes: The charger contains high-voltage components. Do not attempt self-repair. Charge the battery and charger in a safe place, out of reach of children. Keep away from flammable or explosive materials. Avoid charging in direct sunlight or rain.

Warning: If you notice a strange smell or excessive heat during charging, stop immediately and contact customer support.

2.5 Quick Use

Before riding, ensure components are installed, firmware is secure, the battery is charged, and you have appropriate protective gear.

Step 1: Adjust Handlebar and Saddle

Adjust the handlebar and saddle height according to your body size for a comfortable riding posture. Ensure the quick-release levers for the seat post and stem are securely fastened.

Note: Adjust the handlebar to a comfortable height based on your riding habits. Adjust the saddle to your hip height, ensuring it does not exceed the maximum insertion line.

1. Insert the battery key into the battery slot and turn it to the ON position. The key should be parallel to the frame.
2. Press the power button briefly (approx. 1 second) to turn on the display.
3. Adjust the headlight so it illuminates the area approximately 10 meters ahead.

Step 3: Adjust Gears

Select the appropriate gear based on riding conditions and personal preference. The bike has 5 gears. Use the '+' and '-' buttons to shift gears. Lower gears are suitable for flat terrain, while higher gears are for inclines. The bike can also be ridden as a normal bicycle without electric assist.

Step 4: Riding on the Road

For your safety, it is recommended to wear a helmet while riding.

Step 5: Brake Instructions

The left brake lever controls the front wheel brake, and the right lever controls the rear wheel brake. Apply brakes smoothly, prioritizing the rear brake first, then the front brake. Warning: Do not brake suddenly with only the front brake, as this can cause instability and a fall.

3. Maintenance Precautions

3.1 Usage Precautions

Safety when using electric bicycles with support:

1. Do not park e-bikes in building lobbies, evacuation stairs, or exits.
2. Do not charge or park e-bikes in residential buildings. Charging time should not exceed 12 hours.
3. Prevent water from entering electrical components. Be careful when cleaning the bike, avoiding water in the charging interface, wiring harnesses, and other electrical parts.
4. When adjusting the seat post or stem height, do not expose the safety line markings.
5. Users and dealers are not permitted to modify the vehicle without authorization (e.g., battery configuration, circuit modification, adding lights or speakers).
6. Do not touch live electrical parts with wet hands or metal conductors.
7. Do not disassemble electrical components without authorization.
8. Avoid prolonged exposure to sunlight or heavy rain to prevent component aging.
9. When cleaning the bike, use clean water mixed with a neutral detergent. Do not disassemble internal parts for washing to prevent short circuits.

Riding Safety: Adhere to national and local traffic regulations and ride safely.

1. Persons under 16 years old are strictly prohibited from riding electric bicycles. Do not lend the bike to individuals unfamiliar with its operation.
2. Ride in non-motorized lanes and do not exceed local speed limits.
3. Transport people or cargo according to legal regulations.
4. Wear a suitable helmet and fasten the chin strap.
5. Braking distance increases in rain or snow. Ride slower and brake gently. Avoid riding in severe weather conditions like heavy rain if possible.
6. Obey traffic rules. Never ride under the influence of alcohol, or while operating with one hand or without both hands on the handlebars.
7. Wear bright, non-restrictive clothing. Avoid open cuffs and wear low-heeled shoes or sneakers.

Things to Note on the Road:

1. Observe traffic rules for your safety and the safety of others.
2. Always wear a helmet and take other relevant safety measures before riding.
3. When starting, accelerate gently to avoid losing control.
4. In rainy or snowy weather, braking distances will be longer. Concentrate on riding cautiously and slowly to prevent skidding and falls.
5. Lower the mechanical gear before parking for the next ride.

3.1.1 Pre-ride Checks

Before riding, check the following:

1. Turn on the power and check if the instrument indicators are normal and the power supply is sufficient.
2. Check if the front and rear lights are functioning correctly and if the headlight angle is appropriate.
3. Ensure the bicycle's horn is in good working condition.
4. Verify that the handlebar and seat post are adjusted to the correct position and that their fixing screws or quick-release levers are tightened.
5. Check the brake levers. Ensure they provide reliable braking and return smoothly after releasing.
6. Check tire pressure, look for cracks or abnormal wear, and ensure there are no nails, stones, or glass embedded in the tires.
7. Confirm that wheel screws are locked and pedal reflectors are present and clean.

3.1.2 Riding and Parking Considerations

1. Turn off the power switch when pushing the bike to prevent accidental acceleration from the throttle.
2. Use boost mode when pushing uphill or carrying heavy loads to assist.
3. When parking, place your feet on a flat surface and turn off the power.
4. Perform regular maintenance and cleaning to keep the bike in optimal condition.

3.2 Vehicle Maintenance and Self-Inspection

Vehicle Maintenance:

1. E-bikes are fully adjusted before leaving the factory. Contact the manufacturer or supplier if you have questions.
2. Regularly check tire pressure to ensure it is within the normal range.
3. Periodically inspect and adjust key components such as the handlebar, folding risers, seat posts, seat tubes, front and rear axles, bottom bracket, flywheels, chains, and wheels to ensure flexible and normal transmission. Tighten any loose nuts or screws promptly.
4. It is recommended to lubricate parts every six months with #3 calcium-based lubricating oil (grease) for components like front axle bearings, pedal bearings, rear axle bearings, headset, and pedal bearings. Apply #30 motor oil to the chain, transmission cables, footrests, and other parts every two months.
5. If wear parts like brake pads, chains, or tires are damaged, replace them with parts of the same model and specifications at a local repair center.

Motor Maintenance:

1. The motor base and end cover are sealed; do not open them.
2. Keep the motor clean and free from foreign substances, corrosive liquids, or gases. Avoid impacting or heating the motor housing to prevent damage.
3. The motor has an IPX5 waterproof rating. Do not wash the motor with a high-pressure washer or submerge it in water. Water entering the motor hub can cause short circuits and damage internal components.

Battery Maintenance:

1. Lithium batteries offer high capacity, long lifespan, and low weight. Their lifespan depends on usage. Charge the battery before it is completely depleted. Avoid long periods of storage without regular charging.
2. Charge the battery fully for the first use. It is recommended to charge for 6-8 hours, but not more than 12 hours.
3. If the lithium battery is not used for an extended period, charge it for more than two hours every month. Avoid storing it with a depleted charge. Deeply discharged batteries can cause irreversible damage.

Danger: Do not disassemble old batteries without authorization. Recycle them at designated locations or authorized service points.

Warning: Do not place the battery near open flames or high-temperature heat sources. Do not dispose of the battery in fire. Do not expose it to direct sunlight in hot weather.
