Three major factors that affect the battery life of electric assist bicycles
① Charging habits accelerate deterioration
"Overcharging" is the main cause of expansion and heat generation. The golden rule is to choose a charger that is 3C certified and has an automatic shutoff function, and to limit charging to less than 8 hours.
② Be careful of environmental stress
Leaving the battery in a car in midsummer or exposed to rain can cause the insulation layer to break down. The temperature around the battery of an electric assist bicycle should be kept between -10℃ and 40℃, with humidity below 60%.
3. Don't overlook signs of aging
"Charging time doubles" and "mileage decreases by 30%" are indicators of when to replace the battery. Cracks in the cable and rust on the connections are also warning signs.

Charging Rules
It is best to stop charging at 80% overnight
Avoiding full charging with a charger with a timer helps prevent lithium-ion crystallization. Overcharging prevention features are now mandatory under China's new standards.
One full discharge cycle per month
If you fully charge the battery once when the remaining capacity is below 20%, the capacity measurement will be accurate. However, over-discharging the battery on a daily basis is strictly prohibited.
Daily Inspection Checklist
- Loose/corroded cable connections
- Battery case deformation/liquid leakage
- Abnormal heat generation during charging (40°C or higher is dangerous)
Safety measures that reduce fire risk by 99%
Modifications that are strictly prohibited
"Increasing battery capacity" and "reusing chargers" overload the electrical circuits, increasing the risk of fire by eight times. According to Shanghai city standards, modified vehicles are prohibited from being driven on public roads.
Ideal storage location
- A well-ventilated place out of direct sunlight
- Install a rain cover on the outlet
- Do not place any flammable materials within 1m of the device.
What if it starts smoking?
Immediately unplug the device and use a fire extinguisher or water to extinguish the fire . Lithium batteries require cooling for at least 30 minutes as internal reactions continue.
Black Knight of the City 0034
This is not a bulky "mama car", but a fashionable car designed for urban youth. The golden ratio body with a total length of 1550mm shows a neat posture when driving around town. The military grade aluminum alloy frame weighs only 43kg but can carry 180kg, and can draw a graceful arc every time you turn when riding alone.
