SAMEBIKE M20 Electric Mountain Bicycle

1. Important Warnings

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

• If lending the electric bicycle to others, ensure they also read this manual to minimize accident risks.
• Always wear a suitable and safe helmet. For night riding, wear clothes with fluorescent and reflective stripes. Do not exceed the speed limit, as this is a primary cause of traffic accidents. Adhere to traffic rules and speed limits.
• Do not touch the charging hole with metal objects, as this can cause accidents due to transient short circuits.
• Factors like zero starting, frequent braking, riding against the wind, carrying heavy loads, or insufficient tire pressure consume significant electric energy and reduce endurance mileage. For optimal endurance, use assist mode, avoid frequent braking or zero starts (prioritizing safety), do not overload, and ensure tires are properly inflated before riding.
• Avoid prolonged exposure of the e-bike to sun or rain, and do not store it in places with high temperatures or corrosive gases. This prevents chemical corrosion of electroplating parts and paint, as well as damage to electrical components, which can lead to operational failure and accidents.
• Your current insurance may not cover situations encountered while riding an electric bike. Consult your insurance company or broker for relevant advice.
• Familiarize yourself with local laws and regulations regarding electric bicycle use. For example, in China, riders must be at least 16 years old.
• Bicycles are vehicles with inherent risks. Always abide by traffic rules. When braking suddenly, brake the rear wheel first, then the front wheel. Braking the front wheel too abruptly at high speeds can cause tipping over. Ride carefully.
