FAQ
A1: Sales rebate, exhibition support, retailer store support, online/offline training, please ask the sales to get more details.
Q2: Why the new scooters/bikes has some dust and slight traces of use?
A2: Our products need to ride the test function before leaving the factory, clean and clear the number of kilometers before packaging and shipping, to ensure that each car is in line with the quality standards of Luyuan, thus you will find some dust and slight traces.
Q3: Does low ambient temperature affect use?
A3: Low temperature will lead to the reduced endurance and power, for example, the temperature is 25ºC when the battery power output is 100%, when the temperature is 0ºC, the battery continuous discharge power is only about 80% of 25ºC, riding in a low temperature environment, it is recommended to slow down, do not accelerate, speeding, and pay attention to the change of the remaining mileage.
Q4: How to deal with vehicle failure?
A4: Please consult your dealer or sales to help you.
Q5: How to maintain the battery when the vehicle is not used for a period of time?
A5: The vehicle is placed for a long time without use, which can easily lead to over-discharge of the battery. It is recommended that the battery be fully charged for storage after each use. If it is not used for a long time, it needs to be charged once a month, which is conducive to extending the battery life.
Q6: Whether the battery/charger can be disassembled without permission?
A6: The battery/charger can not be disassembled without permission, and the warranty service will be lost after disassembly.
