Battery Maintenance

A well-maintained battery performs well even after high mileage. Charge the battery after each ride to prevent the battery from draining from a full charge. Batteries perform best when used at room temperature (70°F [22°C]). However, Using it at temperatures below 32°F (0°C) will degrade performance. In general, at -4°F (-20°C), battery performance drops to half of that at 70°F (22°C). When the temperature rises, battery life will resume.

Refer to local laws and regulations regarding battery recycling and/or disposal.

Under normal circumstances, a fully charged battery can hold power for 90 days in standby mode. Remember to charge the battery after each use. Draining the battery may cause permanent damage to the battery. Electronics inside the battery record the charge and discharge of the battery. Damages due to over-discharge or over-discharge are not covered by the warranty.

Notice

• Do not perform any maintenance while the E-bike is powered on or charged.
• Do not store or charge the battery within the temperature range of 20°C-25°C / 68°F-77°F. Do not pierce the battery.
• Do not attempt to disassemble the battery to avoid fire.
• When the ambient temperature exceeds the maximum operating temperature (see instruction manual), do not ride the electric bike.
• Temperature will limit maximum power/torque. Otherwise, personal injury or property damage may occur. Before cleaning, make sure the power is turned off and the charging cable is unplugged. Otherwise, you may damage electronic components. Proper cleaning of your E-bike can guarantee a longer lifespan and a smoother ride.
• Wipe the outer body of the E-bike with a soft and dry microfiber cloth.
• Check around the wheel to make sure there are no foreign objects. The design of this electric bike makes wheel maintenance easy.
• The E-Bike has IPX4 water resistance, which means it can withstand splashes. However, don't submerge the E-bike in water.
• Do not use alcohol, gasoline, acetone, or other corrosive/volatile solvents to clean the bike. These substances can damage the exterior and the internal structure of the bike.
• Do not allow water and liquids to enter the electric parts or battery of the E-bike.

Storage

The bike should be fully charged before storage to prevent the battery from being over-discharged after long-term storage.
If the electric bike is to be stored for more than a month, discharge and charge the battery at least once a month.

Notice

• Do not store the electric bike outdoors for extended periods of time. Exposure to sunlight and extreme temperatures (both hot and cold) accelerates the aging process of plastic parts and can reduce battery life.
• Store in a cool dry place.
• Do not store in dusty environments as damage may occur over time. Cover the bike to prevent dust from entering.

For your safety

For safe riding, please read the following information carefully. Before riding, be sure to check that your brakes are working properly.

Before Your First Ride

• Check whether the quick-release screws and seat are firm, and whether the brakes are effective.
• Check seat, gears, and tire pressure. Proper tire inflation can reduce flat tires and improve performance, including distance traveled per inflation.
• Check the handlebar and screws at least weekly.
• Performing the above routine checks before and after each ride can help you keep your bike performing at peak performance and spot potential problems before they become a safety hazard.

Bike Mechanic Check Every Six Months

• Bikes require regular maintenance. Take your bike to your local bike shop twice a year for tuning. Critical components should be inspected frequently, repaired and adjusted by an experienced mechanic.

Notice

• Wear an approved helmet and other protective equipment to reduce any possible injury.
• Helmets can reduce serious head injuries by 85%.
• Elbow pads can reduce elbow injuries by 82%.
• Knee pads can reduce knee injuries by 32%.

• To avoid accidental movement while waiting at a traffic light, set the speed mode to zero, or apply brakes.
• When riding, make sure your feet are always on the pedals and your hands on the handlebars. It is dangerous to take your feet off the pedals in riding.
• Never ride the electric bike for dangerous actions. Failure to exercise good judgment or heed the above warning increases the risk of serious injury and, In rare cases, death.
• Make sure the battery is fully charged, especially for long trips.
• For your own safety and the safety of others, obey the speed limit, ride at a speed you are comfortable with, and be prepared to stop at any time.
• Keep a safe distance from other riders to avoid collisions.
• Be aware of your surroundings and avoid obstacles and unsafe surfaces.
• Ride in the open and flat. Try to avoid slopes or places with many pedestrians.
• Do not ride at high speeds, on uneven terrains, in bad weather or in other unsafe conditions.
• Never use the electric bike for anything that could cause personal injury or property damage.
• Do not attempt to carry passengers or heavy objects. This bike can only hold the weight of one person at a time. Do not exceed the weight limit.
• Ride E-bikes only where permitted. You must obey local laws and be courteous to pedestrians.
