It is obvious great technology comes with many minute problems and this is one of the most common problems that riders may encounter is Error Code 30. This error can be frustrating, but with a systematic approach, it can be resolved.
And That same happened with electric bikes. And to my surprise initially, I use to think ebikes or e-scooters will not have these kinds of technical issues but one day I got it on my Ride1up ebike.
I googled in between the road and searching for solution and in this article will guide you through understanding, diagnosing, and fixing Error Code 30 on your e-bike the way I did.
What I did? How I fix? – Read below 👇.
What is Error Code 30?
Error Code 30H = Communication Failure
An error 30H means there is a communication error somewhere in the system be it from the throttle or controller to the screen at some point something is going wrong where there is a lack of communication between the components
Why I’m Seeing Error Code 30 on My E-Bike?
Riders mainly see this issue because of:
1. Water Damage
This generally happens when you spray water on your bike to clean it or exposing in rain can cause corrosion and this lead to malfunctioning in ebike.
2. Loose Cable Connections
While riding bike goes through too many bumps and jumps and this will loosen up the cable connections. So, must check whenever you get this error.
3. Bent/Broke Pins
This is one of the most common reasons for getting communication error because getting pins bend has the high chances, broken pins can not fixed at home you need to take it to service centre but bend pins can be fixed through tools like screwdriver.
4. Faulty Display or Controller
With time controller and display starts malfunctioning and break the communication between components.
5. Damaged Wiring
Sometimes wires get cut, rigged or pinched this leads to communication errors.
Tools and Materials Needed
- Multimeter (for checking electrical continuity)
- Screwdrivers
- Electrical tape
- Replacement cables or connectors (if necessary)
- Clean, dry cloth
Step-by-Step Guide for Fixing Error Code 30
Inspecting Wires
Near handle bar you will see 4 wires that belongs to brake, throttle, screen & the button pad. First, we will check 3 wires excluding screen one and the obvious reason how we gonna check error 30 gone or not.
Simply disconnect them by pulling apart and see if pins are intact, no bends, no rust and female side is clear and pins are lining correctly. Now do this with all the wires except display and check error 30 has disappeared between each connection or not.
Now, if you still showing the error 30 then it means problem is between the screen and rest of the system.
Inspecting the Controller
So, now we will going to check the controller and 9 pin plug that comes from controller and goes up to the handlebar.
Now, disconnect the 9 pins plug and check is there any issue or not and if you see in the below image one pin is hitting wrong place in our case. So, let’s repair the pin.
Take a screwdriver or any tool that would place the pin correctly. Once it’s done then plug it in again and see if it’s still showing error 30 or not. But in my case it’s gone but if it’s still showing in your case that means you could have problem in the controller or maybe the main wire itself or last there could be problem with the motor that’s very very rare thing.
Let’s check the motor
Now, when you unplug the motor cable, you will see error 24H . If you do have error 30 in your system then it will reappear a few seconds after 24 has. As long as 30 appears it means your motor is totally fine.
Now, you must be thinking what is error 24H means to know read here.
Now, after doing everything it concludes with that issue is with LCD screen, the main wire as i mentioned earlier & of course the controller.
Now how to fix this at home?
Sorry, you cannot fix this at home you have to take it workshop/service centre.
2. Contact Tech Support

Conclusion
Error Code 30 on an e-bike can be a nuisance, but with careful inspection and a methodical approach, it can be resolved. Whatever I have showed in this troubleshooting guide just proceed with maintenance checks like all connections are secure, checking for damaged wiring, and testing components, you can diagnose and fix the issue.
Avoid spraying cleaners to the crucial components as it corrode the parts and it will help in prevent such errors in the future, ensuring a smooth and enjoyable riding experience. If you encounter persistent issues, don’t hesitate to contact tech support.
I hope this article helped you in resolving error code 30H that is also known as communication failure. I’m waiting for you positive comments and if there is any feedback I’m open to that as well, comment section is all yours.
