Inspection and Adjustment after the Wear-in Period
After buying a new motorcycle, users should pay attention to the break-in of the new motorcycle (the break-in period is 500 miles at the beginning, and the odometer reading is the final measure). The break-in quality of new motorcycles directly affects the lifespan of electric motorcycles. The break- in period is the process in which the newly purchased electric vehicle becomes more compatible, consistent and smooth after running for a while. After the break-in period is over, the electric vehicle should be adjusted thoroughly to ensure the normal operation of the whole vehicle in the future and to make the electric vehicle run faster and longer. The main adjustment items are as follows:
1. Bearing adjustment After the break-in period, the raceway surface between the steel ball, the shaft bowl and the shaft stop will be smoother and more consistent under the operation of the stressed load, but the gap should be properly adjusted. 2. Adjustment of brake system After a period of use, the coordination of various parts of the brake system is more perfect, especially the brake shoe and the inner diameter surface of the brake drum are more consistent after running-in. To drive safely, the slack of the brake system should be adjusted appropriately. 3. Fastener adjustment After the break-in period, the bolt or nut may loosen after the vehicle is shaken and jolted, so it must be checked and tightened in time to ensure the smooth running of the electric vehicle.

Maintenance of Drive Motor
The vehicle adopts a DC, brushless rear-wheel drive motor with an efficiency of more than 85%, which has the advantages of strong hill-climbing performance, fast speed, low running current, long mileage, and good skidding effect, etc.
1. Water intake of the drive motor will cause insulation degradation. After the motor is disassembled and drained, it can be dried by blower or sun drying. Then the motor resistance and Hall sensor shall be tested and replaced if damaged.
2. Inadequate battery charging will result in short continuous driving range of electric vehicles and weak driving motor, so the battery should be kept fully charged.
Caution There is no direct interchange between low-speed brushless motor and high-speed brushless motor.
Inspection of wheels
1. If the tire pressure is too high, the riding comfort will be reduced and the wear of various parts will be accelerated. If the tire pressure is too low, the rolling resistance of the tire will be increased and the consumption will be increased. In serious cases, local delamination of the tire will result in tire burst.
2. When the tire valve core leaks, it should be repaired or replaced. When the inner tube leaks, repair or replace the tire.
3. Regularly check and adjust the wheels at our special service center.

Common Fault Diagnosis and Troubleshooting Methods
I. Fault: motor does not turn. Fault causes and solutions: 1. Fault cause: the power fuse of the finished vehicle is blown or the circuit breaker is tripped, causing the power supply circuit to be blocked;
Solution: a. Replace safety tube; b. Reopen the air switch. 2. Fault cause: battery voltage is too low, resulting in the controller under voltage protection state;
Solution: charge battery. 3. Fault cause: the battery voltage is too high, which causes the controller to be in overvoltage protection state;
Solutions: a. check the reason of high battery voltage and troubleshooting; b. replace the battery 4. Fault cause: Speed control handle failure;
Solution: Replace the speed control handle. 5. Fault cause: brake failure causes the controller to be in brake protection state;
Solution: check whether the brake switch and brake light are short-circuited. If they are short-circuited, please replace the corresponding parts. 6. Fault cause: anti-theft fault, when the whole vehicle is in anti-theft state, the whole vehicle circuit is connected at this time, and the motor will not rotate because the controller locks the motor against theft; Solution: unlock the anti-theft status with the anti-theft remote control panel. 7. Fault cause: The side bracket was not retracted or the side bracket switch was short- circuited, causing the side bracket to be in a protected state; Solution: a. fold up the side bracket; b. or replace the side bracket switch. 8. Fault cause: Short circuit or open circuit in the motor phase line, resulting in controller protection; Solution: Repair or replace the motor assembly. II. Fault: The motor can operate normally, but the speed is too slow. 1. Fault cause: low battery voltage; Solution: Measure the battery voltage with a multimeter. If the voltage is too low, recharge the battery immediately.
24

2. Fault cause: In low-speed gear;
Solution: Shift to high gear.
3. Fault cause: The handle is malfunctioning, and the signal output voltage is too low;
Solution: Check and maintain the speed regulating handle.
III. Fault: The motor can rotate by twisting the speed knob, but it stops again after a few seconds and there are repeated failures.
Fault cause: this fault is mostly caused by low battery voltage of electric vehicles. The battery has a floating phenomenon, that is, the battery voltage is relatively high when no load is applied, and the battery voltage drops sharply after the load is applied, which will be lower than the under-voltage protection value, causing the controller to under-voltage protection and stop the motor drive output.
Solution: Measure the battery voltage with a multimeter. If the voltage is too low, recharge the battery immediately.
IV. Fault: The noise and current of ordinary speed riding motor are relatively large.
1. Fault cause: The MOS tube of the controller is damaged;
Solution: Replace the controller.
2. Fault cause: The motor is damaged; Such as turn-to-turn short circuit of the motor winding, large interference of Hall signal output, etc.
Solution: This kind of fault is difficult to be measured, detected and processed by multimeter, so replacement method can be used to replace the new motor to see if the problem still exists, and if the problem is solved, the motor is faulty. 3. Fault cause: The mismatch between the controller and the motor Hall will also cause the motor noise; Solution: Replace the controller.
V. Fault: In non-loaded condition, screw the governor handle at the place with excessive load or large slope to start the electric vehicle. Sometimes, the motor will have forward force, but the electric vehicle still does not move forward. After a few seconds, the force disappears. After the handle is reset, turn the handle again, and the phenomenon will repeatedly appear.
Fault cause: This phenomenon is often called “locked-rotor” in electric vehicles. When starting, the load is very large, but the motor does not rotate, so the controller will not produce commutation action. Large current will pass through the same set of MOS tubes on the upper and lower bridges of the controller and the same winding of the motor, which will easily burn down the controller and the motor for a long time. In order to protect the controller and the motor, the motor drive output must be stopped in a safe time period, which is the “locked-rotor protection” of the controller.
Solution: In case of the above situation, it is necessary to reduce the load of the electric vehicle or wait for the electric vehicle to restart at a place with a small slope.
Tips: do not let low-power electric vehicles run for a long time under heavy load (heavy load or climbing a steep slope), so as not to affect the service life of the motor or controller.
25

VI. Fault: When the electric vehicle starts, sometimes it needs help. 1. Fault cause: Controller fault;
Solution: Replace the controller. 2. Fault cause: Poor contact motor phase line; Solution: reconnect the motor phase line. VII. Fault: In the process of riding, the vehicle will walk for a moment and stop for a moment 1. Fault cause: Poor contact of power cord, handle cable, motor phase cable and Hall cable;
Solution: Check the connection of each node to ensure that the contact parts are firmly contacted without poor contact. 2. Fault cause: Low battery voltage;
Solution: Check the battery voltage and replenish it in time. VIII. Fault: When the speed control handle is not reset during the whole vehicle riding, the brake can not protect against power failure. 1. Fault cause: The brake switch is damaged;
Solution: Test and replace the brake switch (or brake handle). 2. Fault cause: The brake switch line is not connected or disconnected; Solution: Test the line and eliminate the corresponding faults. 3. Fault cause: The brake input circuit inside the controller is broken;
Solution: Replace the controller. IX. Fault: After pinching the brake in vehicle riding, sometimes the speed regulation has no effect. Fault cause: Brake handle fails or is damaged after being used for a long time;
Solution: Replace the brake switch. X. Fault: Short cruising range. Failure cause analysis: The short endurance mileage is related to many factors, and the factors related to the vehicle manufacturer: the efficiency characteristics of the selected motor of the vehicle, the capacity and life characteristics of the battery;

Other factors relevant to objective circumstances: the weight of the rider, the road conditions of frequent riding, whether the brakes need to be used frequently, the riding habits of the rider, and so on. 1. Reason of the motor itself: a.Low efficiency-the amount of electric energy converted into mechanical energy by motor is reduced, while the amount of loss used for heating is increased. This kind of motor does not run for a long time and generally has a high-temperature rise; b.Magnetic steel demagnetization-with the increase of service timeit,s certain that magnetic steel demagnetization will occur,but it is only a matter of how much.However, if the quality of the magnetic steel itself is not good and the demagnetization performance is poor, the magnetic steel will be easy to demagnetize, resulting in a significant decline in motor performance, an increase in operating current and a shortening of driving mileage.
