Precautions Before Riding
Before riding, check tire pressure and ensure the handlebars are properly and securely mounted. Make sure the battery is fully charged.
If the battery runs low during a ride, maintain smooth and slow movement. Recharge as soon as possible.
Before each charge, inspect the charger, cables, and plugs for any damage. Do not use a damaged charger.
Braking distance on slippery surfaces is longer than on dry surfaces. Start braking earlier for safer stopping.
Avoid using the electric scooter in rainy, stormy, or snowy conditions. Water ingress into electrical components (controllers, motors, batteries) can cause irreversible damage, including battery explosion.
This product is for single-rider use only. Do not carry passengers. Do not ride if you feel unwell or are under the influence of alcohol or drugs.
The scooter is not a toy. Like any vehicle, there is a risk of falls, collisions, or other dangerous situations. Do not lend your scooter to individuals unfamiliar with its operation. If allowing others to ride, ensure they are aware of all warnings, precautions, and safety instructions, and can operate the product safely and responsibly.
