Things to pay attention to when buying electric tricycles

After buying a car, check whether the parts of the vehicle are normal, whether the connecting parts are loose, whether the instrument display is normal, and whether the front and rear brakes are flexible. Pay attention to the tire pressure before each ride, and the pressure should be moderate. The lack of air pressure increases the friction and increases the power consumption when riding laboriously, and the speed of the car should be reduced. Always check the flexibility of the brakes, whether the screws of the whole vehicle are loose, and the chains and flywheels need to be refueled. Loosen the speed control handle when braking to avoid damage to the motor and other parts. When you get off the car, you should turn off the power to prevent accidental turning of the speed control handle when the car starts suddenly. Charge it immediately after receiving the car. Do not cover anything on the charger, pay attention to ventilation and waterproofing; the charger contains high-voltage lines, do not disassemble without authorization. The battery should be added with distilled water after a period of time to prevent the battery from drying out and affecting the battery life. The electric drawing car that has not been used for a long time should be started every 25 days or so, and run at a medium speed for about 20 minutes, otherwise it will be left for too long and the electric drawing car will not start when the car is used. In normal driving, you should always check whether the small holes on the battery cover are ventilated. If the small holes on the battery cover are blocked, the hydrogen and oxygen produced cannot be discharged, and the battery shell will be broken when the electrolyte expands.
