Notes: The charger contains high-voltage equipment. Unauthorized repairs are strictly prohibited due to the danger involved.

Warning: The battery and charger must be placed in a safe, well-ventilated, and dry location, out of reach of children and away from flammable, explosive, or hazardous items (such as sofas, etc.). Furthermore, the device must not be charged outdoors to avoid accidents such as electrical short circuits and fires due to rain or similar elements.

Warning: If you notice an unusual smell or if the battery or charger becomes excessively hot during charging, stop charging immediately and contact customer service.

2.4 Quick Operation

Before using the product, please follow the installation manual to correctly install the relevant components. Ensure that no fasteners are loose, the battery is sufficiently charged, and appropriate safety measures for riding are taken.

Step 1: Adjust Handlebar and Saddle

Adjust the handlebar and saddle to a suitable riding height according to the rider's size. Ensure that the quick-release mechanism of the saddle and the handlebar screws are fully tightened. It is recommended to adjust the handlebar to a comfortable height based on your riding habits and the saddle to the height of your pelvis. However, the height should never exceed the safety mark.

Step 2: Turn On and Adjust Headlight

1. Press the power button for 1 second to turn on the bicycle.
2. Hold the '+' button to turn on the light.
3. Adjust the headlight so that it illuminates the area 10 meters in front of you.

Press the power button for 1 second to turn on the bicycle, and hold it for 3 seconds to turn it off.

Step 3: Adjust Gear/Mode

Switch riding modes according to road conditions and personal needs. This bicycle is equipped with 5 support levels. Use the '+' and '-' buttons to change the levels. Level 1 is suitable for relatively flat roads. The steeper the incline, the higher the level can be set. Note: When the bicycle is in PAS 0 mode, there is no electric assistance, and it functions like a normal bicycle.

Step 4: Riding

Start riding. Wear a helmet before riding.

Step 5: Braking Instructions

The left brake controls the front wheel, and the right brake controls the rear wheel. Always apply the right brake first, followed by the left brake, to gradually slow down and stop. Warning: Never apply the front brake abruptly alone, as this can lead to a loss of balance and an accident. The maximum load for this electric bicycle is 120 kg; do not exceed this weight limit.

2.5 Instrument Settings

3.2 Maintenance and Self-Inspection

Maintenance and Self-Inspection

1. The electric bicycle was adjusted before leaving the factory. If in doubt, please contact the manufacturer or supplier.
2. Regularly check tire pressure to maintain it within the normal pressure range.
3. Main components such as the handlebar, folding tube, saddle, seatpost, top tube, down tube, seat tube, chainring, chain, front wheel, and rear wheel should be checked and adjusted regularly to ensure they function properly. If screws are loose, please tighten them promptly.
4. It is recommended to fill the bearings of the axles, the fork, and the pedals every six months with 3# calcium-based grease; fill the chain, derailleur, and bicycle stand every two months with 30# motor oil.
5. If wear parts such as brake pads, chain, tires, etc., are damaged, please visit a local maintenance point to replace them. Please replace them with parts of the same type and specification.

Motor Maintenance

1. The motor base and end cap have been sealed. Please do not open the motor.
2. Keep the motor clean. Ensure that no foreign objects, corrosive liquids, or gases enter the motor. Do not strike the motor housing to avoid damaging the motor.
3. The motor is IPX5 waterproof. Do not clean the motor with a water spray gun or immerse the motor in water. If the water level reaches the middle of the motor hub, it may cause a short circuit of the bicycle and damage the electrical components.

Battery Maintenance

1. Lithium batteries have high capacity, long lifespan, and light weight. Their lifespan depends on your usage habits. Please charge the battery regularly and promptly. Do not store the battery for extended periods.
2. The battery must be fully charged before the first use. It is recommended that each charging time be 6-8 hours. The longest charging time should not exceed 12 hours.
