1. Important Warning ⚠️

This manual contains important safety performance information and service information. Please read the following warning content carefully before using the product for the first time.

• If you lend your electric bicycle to others, please let them read this manual to help decrease the risk of accidents.
• Please wear a suitable and safe helmet before riding. Wear clothes with fluorescent and reflective stripes when riding at night. Do not exceed the speed limit, as it is a main reason for traffic accidents. Always abide by traffic rules and do not exceed the speed limit.
• Do not touch the charging hole on the bike or insert metal objects into it, as this can cause accidents due to transient short circuits.
• Zero starting, frequent braking, riding against the wind, carrying heavy loads, or insufficient tire pressure all consume significant electric energy, reducing the endurance mileage. For optimal endurance mileage, consider the following:
  1. Use assist mode.
  2. On the premise of safety, avoid frequent braking or zero starting.
  3. Do not overload the bicycle.
  4. Before riding, check tire pressure and ensure it is adequately inflated.
• Avoid prolonged exposure of the e-bike to sun or rain. Do not store it in places with high temperatures or corrosive gases, as this can damage electroplated parts and paint surfaces through chemical corrosion, and potentially damage electrical parts, leading to operational failure and accidents.
• Your current insurance may not cover situations encountered while riding an electric bike. Please contact your insurance company or broker for relevant consultation.
• If using the e-bike in your country, refer to local laws and regulations. For example, in China, riders must be at least 16 years old.
• Bicycles are vehicles with inherent risks. Please be sure to abide by traffic rules. When emergency braking, brake the rear wheel first, then the front wheel. Braking the front wheel suddenly at high speeds can cause tipping over. Please ride carefully.
