Having an error on the screen of the electric bike is one of the things that reduce your sense of confidence in your bike, especially if the error appears constantly on the screen of your electric bike.
Today we will discuss the error 30 that appears on the screen of the electric bike and the reason for dedicating a post to this particular error because it is very important and it can completely disable the bike in some cases.
What Does Error 30 Mean On An Ebike?
Error 30 means that there is a problem in the communication between the controller and the rest of the bike components that are directly connected to it.
Reasons for error 30.
In this section, we will explain the reasons that lead to the appearance of a 30 error on your electric bike.
1-Throttle Wires or Function issue.
2- Brakes Inhibitors.
The second component that can cause Error 30 is a problem with the brake inhibitors, usually the brake cable itself or the brake sensor magnet.
If the problem is in the brake sensor, you can determine it by using the brakes, and if you notice that the electric current does not cut off when you use the brakes, this indicates the presence of the problem.
3-Display connection.
The third part that can cause error 30 is the occurrence of a problem with the bike screen itself.
It can be determined if there is a problem with the screen cable or not by several indicators, the first of which is to check the screen readings.
For example, if the bike battery is charged and the battery indicator is found to give you that it is empty, then this is Evidence of a problem in the communication between the controller and the screen.
4- Installing a new controller.
One of the reasons that lead to the appearance of an error 30 on the electric bike is that the controller has changed recently, and the reason for this is that the new controller is not compatible with one or more components of the bike.
You can know if error 30 appears because you changed the controller or not by checking whether all the components connected to it are working or not.
If they are working and you find there is an error 30, this indicates that the new controller is not suitable for the bike display.
In this case, you have two options, first to change the display or to ignore this error.
5-Other component connections issue.
The components we mentioned earlier are considered the most important reasons that lead to the appearance of error 30 on the electric bike, but there are other parts that can cause this error, including all the sensor cables connected to the controller, as well as the motor cable.
But the possibility of these parts causing this error to appear is rather small.
Step By Step to Fix error 30 on an Ebike.
In this part, we will explain how to solve the 30 error step by step so that you can determine which part of your bike is causing the problem.
Step 1: Check if all ebike parts are working.
Before you enter into the steps of identifying the problem, such as tracing the wires and checking the controller and the rest of the parts, you should first know whether the error affects the ebike functionality or not.
You’ll do this by riding your bike for 15 minutes and trying all the parts starting from the throttle, the brakes, the sensors, the PAS speeds, and everything.
I am asking you to do this step because it will save you a lot of time if your electric bike is working perfectly and you still see an error 30, it means that the problem is in the wire connecting from the controller to the screen!
Step 2: Check the controller.
There are some cases in which you will find that when you start the bike, error 30 will appear for some minutes and then the screen will turn off automatically.
Here, I do not want you to check the wires but start by doing a test for the controller. You can do this test in two ways, either by using a multimeter or using a control test device (the price is about $ 10 on Amazon)

After some testing work, you will know if the controller is working and can communicate with the parts of the bike or not. In 90% of the cases, the controller will be the problem.
Step 3: Check the Wires.
If you did the first step and the bike was running and you didn’t have the problem mentioned in the second step.
The third step for you is to check that all wires are connected well and that there are no cuts or breaks in the internal pins of the connectors.
If you find the internal pins are warped and not connected well, you can adjust them using a thin screwdriver.
But if there is a break in the pins, the connector must be changed.
Step 4: Reset the controller.
If you have done all the previous steps and made sure that there is no problem with the wires and the controller is intact, but error 30 still appears on the screen, then the last solution for you is to do a rest of the controller itself.
The reason for this is that there is a parameters in the controllers, if any unintended change occurs in it, this error can appear.
On the other hand, if you have changed the controller recently, resting it will help you fix this error
