Introduction
This manual provides essential information for the safe and correct operation of your new Kukirin electric scooter. Please read these instructions carefully before use to ensure optimal performance, comfort, and enjoyment.
Safety First: For your safety, it is mandatory to wear a helmet, knee pads, elbow pads, and wrist guards when riding an electric scooter to minimize the risk of injury. Recommended rider age is 14-60 years, and height is 130-190cm.
Precautions
To fully enjoy the performance, comfort, fun, and safety of riding, it is important to familiarize yourself with your new electric scooter. For more information and correct operation, please read these instructions carefully.
It is important to perform the first ride in a safe and controlled manner, staying clear of cars, obstacles, and other riders. Do not ride on highways, public roads against traffic, or in heavy rain. Slow down and navigate around flooded roads.
The electric scooter is a vehicle that carries inherent risks. Do not use your phone or wear headphones while riding. Understand and adhere to local traffic regulations for electric scooters on public roads. For your safety, always wear a qualified helmet before riding. It is also recommended to use protective gear such as elbow and knee pads for enhanced protection.
Electric scooters are often supplied without mandatory basic equipment, which can vary by region. If you intend to ride on public roads, ensure your scooter is equipped with the legally required basic equipment according to local laws and regulations.
This product is intended for personal use only. Do not use it for commercial or other purposes. Keep this user manual for future reference.
Warnings
Before riding, check tire pressure, ensure the handlebars are correctly mounted and tightened. Make sure the battery is fully charged. If the battery depletes during riding, continue at a slow, steady speed and recharge as soon as possible.
Always inspect the charger, cable, and plug for any damage before charging. Do not use the charger if it is damaged.
Braking distance on wet roads is generally longer than on dry roads. Brake earlier to stop safely.
Avoid riding the electric scooter in rain, storms, or snow whenever possible. Exposure of electrical components (control unit, motor, battery) to moisture or water can cause irreversible damage or battery explosion.
This product is for use by a single adult rider only. Do not carry additional passengers. Do not ride if you feel unwell or are under the influence of alcohol or drugs.
The scooter is not a toy. Like other vehicles, riding carries risks such as falls and collisions. Do not lend the scooter to anyone unfamiliar with its proper use. If allowing others to ride your scooter, it is your responsibility to ensure they understand all warnings, instructions, and safety precautions, and are capable of using the product safely and responsibly, protecting themselves and others.
Keep the scooter away from flammable objects and open flames.
