Risk of accident and injury

• Incorrect operation of the e-bike due to insufficient knowledge may cause an accident. Please familiarize yourself with the features of the e-bike before riding.
• Familiarize yourself with the brake lever in advance if you are not sufficiently aware of the front and rear brakes’ placement. Please also adjust accordingly before riding.
• Please make sure the brakes are properly adjusted and function well.
• CAUTION: Hardware may not be fully tightened, including but not limited to bolts, nuts, the front hub shaft, the rear wheel, steering mechanisms(handlebar, stem), the brake system, the driving system, pedals, etc. To reduce the risk of injury, ensure that all bike hardware is locked tightly and correctly into position and that there is no loss of equipment, breakage, or other types of damage.
• CAUTION: This bike is designed for adults. Children may only ride under the supervision of adults. To reduce the risk of accident and injury, make sure that the bike and any of its structures are not within the reach of children under the age of 3.
• CAUTION: Component breakage due to improper use of the bicycle may occur.

Risk of accident and injury!

• Do not ride over ramps or mounds with the bicycle.
• Do not ride this bicycle in cross-country cycling.
• Do not ride the bicycle over stairs, rocks, or other steps with a height greater than 15 cm.
• Improper additions or alterations to the bicycle and incorrect accessories can cause the bicycle to malfunction.
• To reduce the risk of accident and injury, do not add any extra accessories that are not purchased from the seller or without getting permission from the seller, including but not limited to child safety seats, trailers, etc.
• CAUTION: Do not ride the bicycle in a risky way.
• To reduce the risk of accident and injury, ride the bicycle only in the correct way. Make sure you are able to control the bike, and do not try dangerous actions, including but not limited to riding with no hands, jumps, and wheelies.
• DANGER: Lack of bicycle maintenance presents risk of accident and injury
• Check the bike before every ride, including but not limited to brake function, tire wearing and PSI, bolt and nut condition, steering, and spokes tension.
• If you hear any abnormal noise while riding, stop immediately and check the entire bike.
