FAQs

Question 1: What does the display error code mean? What is the reason for it?
Answer: Except for communication errors which are actively reported by the display, all other error codes on the display are reported to the display by the controller, and the display shows them.

1. The communication error is because the display cannot detect a controller data reply within 10 seconds, Possible reasons:
2. The communication wire harness between the display and controller is not connected correctly or the wire harness is broken ;
3. The protocol between the controller and the display does not match ;
4. The communication wire of the display is burned;
5. Possible reasons of Hall sensor failure: ① The motor Hall sensor is damaged; ② The Hall sensor wire is connected incorrectly or not properly;
6. Possible causes of throttle failure: ① The throttle is not in place; ② The throttle is not connected properly; ③ The throttle is damaged;
7. The motor phase position loss. Possible reasons: ① The motor phase position wire is not connected properly or correctly; ② The motor phase position wire is short circuited;
8. Possible reasons of brake failure: ① Brake is not in place ② Brake is damaged or not connected.

failure

The power-assisted mode matches with the gear shift to achieve the riding experience of labor-saving and power-saving.
In the setting of power assist riding, on few slopes and good road conditions, it is recommended to match with variable gears, 7-6 high-speed gears, with the best power-saving effect and speed ratio. In case of large slope road conditions, gear 4-7 is adopted, which can easily and effortlessly climb the slope. Riding with power-assisted mode, if using speed shifting &climbing mode on a flat road will waste electric power and be accompanied with the feeling of empty treading.

Maintenance and use skills of electric bicycle

The maintenance methods of electric bicycles under different use conditions mainly include the following points.

Influence of temperature
Temperature has an impact on the use of lithium batteries. Generally speaking, the impact on the use of lithium batteries at room temperature is not significant, but when the temperature is higher than 40″C or lower than-10’cthe discharge capacity of lithium batteries will change. For example, if the temperature is below 0’C in winter, the effect will be affected. When the battery is fully charged,the driving mileage will be shortened, because, under this condition, the battery capacity can only be released by 60%70%. Therefore, the driving mileage when the battery is fully charged in winter will be much less than in summer.

Maintenance method

1. When the temperature is low in winter, the battery should be placed indoors, and the charging should also be carried out indoors. After the battery is fully charged, the charging time should be extended for another two hours
2. In summer, avoid the sun exposure of batteries. Avoid charging the battery at high temperatures. Avoid charging the battery immediately after use in high temperature Do not charge for too long. The battery needs to be charged for another one or two hour after the red indicator turns green.
3. Avoid exposure to the sun and rain. Although the electric bicycle has good waterproof performance, it can still ride in rainy and snowy weather, but when passing through water puddles and ponding and other roads, pay attention to the wading height, which shall not be higher than the motor, to prevent the motor from damage caused by water inflow. Do not use a high-pressure water gun to wash the electric bicycle, to avoid damage caused by water entering the electronic parts and accessories
4. Frequent braking is bound to be accompanied by frequent start-up, which will lead to frequent large current discharge and power cut-off of the battery, which has a certain impact on its life.
   Countermeasures: pay attention to safety when driving, drive at a proper speed, and try to avoid frequent braking.
