People who use electric bikes often get some error codes on the display. Getting error codes are something that no rider wants to see. Because generally, error codes indicated that there is something wrong with the bike. New riders may not know all these error code facts. Thus, this article will show you the electric bike error codes in detail.
With any error, the e-bike started flashing. At this time, you should open the eBike app from your smartphone and can get the detailed error description. Every error code defines different issues with the bike. So, let’s find out the common errors and their codes.
Common Electric Bike Errors
The electric bike comes with some common errors, whether it’s an expensive one or an average priced electric bike. These errors may affect the electrical system of the bike. Some common electric bike errors are-
1. Throttle Error
Many riders have a tendency of pulling back the throttle cable and let it go even without a slow release. This wrong tendency will lead the throttle abnormality to break or damage.
2. Speed or Torque Sensor Error
The speed or torque sensor errors can get some errors as they have been overused. Also, the released dust particles from the brake levers can cause speed sensor error.
3. Battery Voltage
Both low voltage and over voltage protection can cause an error. If you use an incorrect battery, then it will go into the sleeping mode or not function accurately.
4. Battery Prongs
If the battery prongs are not lined up correctly, the electrical circuit won’t be complete. This thing prevents the battery from working effectively.
5. Communication Abnormality
Communication error issues can cause while there is an error between the controller and display. Also, due to bad or cheap cables, this issue can happen.
6. Motor Open Phase Error
If your bikes have any error between the battery and controller or motor plug and controller, this can happen. Motor hall signal error can also occur due to inaccuracy between motor and controller.
Usually, errors occur when the sensor becomes unable to calibrate correctly. Also, when the software encounters and the connection interrupted. So, before we go for the electric bike error codes here are some general tips to solve these common problems.
- Switch your electric bike off and wait for 10 seconds. With a computer, you can reboot it. This thing works wonderfully.
- Look out for the batteries and see if they are installed and fully charged or not.
- Properly inspect all the visible connections and see if the display is adequately engaged or not.
- Make sure the spoke magnet is in the right place, and it’s not twisted. With the missing magnet, the e-bike motor can’t determine the speed appropriately with speed sensor. It will switch into an emergency mode or stop working completely.
All Electric Bike Error Codes List
Error codes can differ according to different brands. If the above tricks don’t work for you have a look at the electric bike error codes below. We showed what the error code means, along with some solutions.
| Error Code | Error Cause | Description |
| 4 | Open Throttle Fault | When throttle becomes unable to return to the start position. Check to find out if anything is blocking it or not. |
| 5 | Throttle Fault | The throttle may get damaged, so inspect the throttle cable. |
| 6 | Low Voltage Protection | The battery is too low to run comparing the e-bike’s capacity. It won’t function correctly, indicated by electric bike error code 6. |
| 7 | Over Voltage Protection | The battery voltage is too high to run the bike. An incorrect battery used on the bike shows electric bike error code 7. |
| 8 | Motor Hall Sensor Fault | At least one hall sensor wire of the motor may be damaged or disconnected. |
| 9 | Motor Phase Line fault | The electric bike error code 9 refers to the minimum one phase wire of the motor that has been damaged or disconnected. |
| 10 | High Temperature Fault | The controller reaches its maximum level to tolerate the temperature indicated by electric bike error code 10. Before using the e-bike, let all the controllers to cool down. |
| 11 | Temperature Sensor Fault | The temperature sensor of the controller has been damaged or disconnected. |
| 12 | Current Sensor Fault | Current sensor of the controller becomes damaged or disconnected. |
| 21 | Electric Current Error | Motor cable is not connected. Bypassing the motor cable, plug connection with the controller into the motor. If error code remains, test with new motor core and controller error. |
| 25 | Brake Abnormality | Unplug brake pads, and to check each brake, restart the bike. If the error remains, try a new controller after unplugging the brakes. |
| 29 | Battery Voltage Sensor fault | The sensors of the battery pack got damaged. See the dealer to solve this issue. |
| 30 | Communication Abnormality | Improper connection between the display and controller-electric bike error code 30. Check for all corrosion damage and cable connection. |
| 31 | Peak Over Current Protection | Too high current voltage to a battery pack. If the system locks, reduce the demand and restart the bike. |
| 34 | ACC-Voltage Error | It’s the power supply error of the electric bike. |
| 35 | Sensors 4V3 Error | Problem is in the power supply sensor. Inspect the motor sensor and peddling sensor wires. |
| 36 | Lights V Error | Electric bikes light line’s power output failure or assist light error. Check the wiring accessory, disconnect it and contact the accessory supplier. |

Hi,
My bike (SLMRO) has a max speed limit of 22km set on it which I want to remove. The bike obviously goes faster if in freemode but I can’t get the right setting. Also the PAS won’t kick in on level 4 or 5
Can you please help or put me in touch with someone?
Regards,
Ranjit
I have a new hub kit and the first time l switched the display on it threw up an 8h code.
I haven’t ridden it at all so is there a faulty sensor in the hub?
Hi my bike keeps giving the error 7 code I thought I had sorted it but it stopped going again
Hello
Can anyone help me please 🙂
My bike HIMO C26 stop working on the display showing error code 30H I’m also give my bike to see someone who understands but they can’t find the problem 😕
Good Evening,
I am assisting my 10th grade grandson with a project he has at school. He chose to convert a GT Avalanche bike from around 2010 +. He swapped out the mechanical rim brakes to hydraulic mt 200 disc brakes. He ordered from Amazon the SW900 ebike kit and 2000 volt battery. He successfully installed parts and battery. He rode the bike a short distance and soon got an 07 message. Seems as though it will start now but shuts down momentarily. We have looked at the chart of errors on this site. Would you give us any feedback as to what your thoughts may be concerning what the problem could be and how to remedy it? O7 error seems to refer to battery voltage, but we would greatly appreciate any suggestions or help from you or whomever we could reach out to. This is a very important project for a big grade and he needs expert help. He is very excited and wants to have it ready for display, Thank you for any interest and help you can provide!

I was named his supervisor and certainly want to help!
My bike is a hot system sold by Hotstream bike’s through Amazon. The code iam getting is E0600. What is it?
Hey David. Have you any clue what a 68h code might be? Its on a dual motor e cells super monarch. No word from dealer so far. Everything is plugged up. Display shows a motor on it and front motor does not work. 500 miles on bike.
Is there a site to buy parts for MZZK E Bikes?
I have a schuck 29 inch front wheel motor conversion kit that I have put on my 21 speed. I used it all year without issue and then sometime during the winter months of feb until now it stopped working. I say Feb because it hooked it up to a battery charger and tested it then to see if it was still working and had no issue with it. So long story short I am getting a motor sensor error when I try to use my throttle. The throttle seems to be signaling fine as it is showing up on my screen when I twist it, but not engaging the motor and that is when the sensor error comes up. Is this a faulty control box by chance. I have replaced the throttle thinking that was the issue as the throttle never returned to the beginning position without me having to put it there manually.
i have the lankeleisi mg600 bike got a new controller and display screen but a error 10 coming up and getting no power to the throttle and pas checked the wires seems ok
Hi David, I have a BTWIN Original 900e Electric bicycle last night I parked it in an open space in I think due to rain it shows the error 70 in it’s display and it’s not working now, can you please let me know about the codes, which part of the cables should I check?
thanks
