FAQ and Suggest Solution
Battery cannot be charged normally / Battery indicator light is abnormal
Suggest Solution:
- First, confirm that the charging method is correct. The correct method to charge the battery is: 1. Connect the plugs at both ends of the charger to the battery first, and then to the power supply. 2. If the green light is displayed after the charger is connected for the first time, it may be that the power supply is not connected properly. Try reconnecting; the red light shows that it is charging normally. 3. It is normal for the battery indicator to show 3 green and 1 red when it is fully charged.
- If you confirm that the charging method is correct and the battery still won't charge, provide a video to the seller to judge the specific problem. The video needs to show: please bring the battery to a brighter space, then plug the charger into the socket. Take a video of the charging process including the battery and the charger. The seller needs to observe the charger indicator and battery indicator status to judge the specific problem based on how the charger and battery react when charging.
Charger and battery indicator status meaning:
- If the indicator light of the charger does not light up: Try plugging in a separate charger (without connecting the battery) and observe the indicator light. If it does not light up, the charger is damaged, and a replacement charger will be arranged.
- If the indicator light of the charger is on but the indicator light of the battery is off: You need to measure the voltage of the battery with a multimeter. The normal charging voltage range of a 36V battery should be between 42-30V. If it is lower than 30V, it may be that the battery cannot be charged. It needs to be replaced. A charger that starts from 0V may be required. After fully charged, the battery can be charged and used normally.
PS: It is normal for the battery indicator to show 3 green and 1 red when it is fully charged.
Fast battery drain
When the new bike is fully charged, the voltage should be 42V. It is normal for the indicator lights to be 3 green and one red after the battery is fully charged. When you are charging the battery, if the charger already shows a green light, do not unplug the charger first. You'll need to let it charge for another hour after the charger already shows a green light to fully charge the battery.
Provide a video to the seller to judge specific problems. What the video needs to show: 1. Fully charge the battery, then start riding and record the kilometers displayed on the instrument when you start riding. 2. Then wait until the battery power is exhausted, shoot the video again and record the kilometers displayed on the instrument.
PS: The battery voltage and cruising range are related to the number of years of use of the battery.
Motor does not work/abnormal sound / PAS mode can't last / Gear Level cannot be adjusted
Suggest Solution:
First, you need to confirm whether the wiring is normal. If confirmed that there is no problem with the wiring, try to check whether there is a problem with the controller or the handle. If any abnormality is found, provide a video to the seller to explain the problem, and contact the seller to reissue the corresponding accessories.
For PAS mode issues: Open the controller box and check whether the connection between the sensor and the controller is loose or not in good contact.
For Gear Level issues: Electric mountain bikes have 3 riding modes:
- Throttle-only mode (motor): Switch the display to Level 0, twist the handlebar, and the motor will give power. PS: In throttle mode, the shift lever cannot be adjusted.
- Pedal-assist mode (pedal+motor): As you pedal, switch between different levels using the LCD display (Level 1-5). The higher the level, the faster the bike will go and more battery power it will cost.
- Pedal-only mode (turn off display): As you pedal, shift gears using the bike shifter (Level 1-7).
Instrument display the error code
When the instrument is abnormal and the error code is displayed, please refer to the following for the meaning of the error code and then check whether the corresponding parts are faulty.
Error code 07:
Reason: Motor temperature is too high due to excessive current of the bike during climbing. The instrument will display error 07 code and turn off to protect the motor.
Suggest Solution:
- Try to turn off the instrument and restart it after 5 minutes.
- The error code will disappear when the motor temperature drops, and the motor will return to normal.
Notice: Do not ride uphill for a long time and do not use the electric mode all the time. The electric mode and power-assisted mode need to be used in conjunction with switching.
Instrument does not work
There are 2 different situations when the instrument does not work:
- The battery is exhausted and the instrument cannot be turned on: Try charging the battery and turning the instrument back on.
- The battery is charged but the instrument cannot be turned on: The first choice is to rule out whether there is a problem with the wiring. If it is confirmed that there is no problem with the wiring, the instrument may be damaged and needs to be replaced.
Instrument shows that the max speed cannot reach the initial value
- Confirm whether the battery can be fully charged.
- Check whether the wheel diameter setting has been changed. PS: 26-27.5-29 three sizes; each size has a different speed.
Pedals fall off
Notice:
- The Right(R)/Left(L) pedal needs to be rotated clockwise and counterclockwise respectively and installed on the Right/Left crank.
- When installing for the first time, be sure to tighten the pedals according to the installation video to avoid pedal falling or damage.
- During riding, please check the pedals regularly. If there are signs of loosening, please tighten them in time to avoid damage to the parts.
