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.
- The communication error is because the display cannot detect a controller data reply within 10 seconds, Possible reasons:
- The communication wire harness between the display and controller is not connected correctly or the wire harness is broken ;
- The protocol between the controller and the display does not match ;
- The communication wire of the display is burned;
- Possible reasons of Hall sensor failure : ① The motor Hall sensor is damaged; ② The Hall sensor wire is connected incorrectly or not properly;
- Possible causes of throttle failure: ① The throttle is not in place; ② The throttle is not connected properly; ③ The throttle is damaged;
- 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;
- Possible reasons of brake failure: ① Brake is not in place ② Brake is damaged or not connected .
- Possible reason of controller failure: controller is damaged or MOS failure .
- Possible reason of abnormal current: controller is damaged or MOS failure .

The power assisted mode match 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 use speed
shifting &climbing mode on flat road will waste electric power and accompany
with the feeling of empty treading

Maintenance and use skills of electric bicycle
The maintenance methods of electric bicycle 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
- 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
- In summer , avoid the sun exposure of batteries . Avoid charging the battery at high temperature . 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
- 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 , so as to prevent the motor from damage caused by water inflow . Do not use a high-pressure water gun to wash the electric bicycle , so as to avoid damage caused by water entering the electronic parts and accessories
- 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.
