Generally, your Ebike setting’s C5 & C10 settings are in charge of resetting your controller. To return your electric bike controller to its factory settings, set it to 1Y. This will erase all the data entered into the controller and revert it to its original state.

Electric bikes are becoming increasingly popular and for a good reason! They are a great way to get around town and can help you save money on transportation costs.

However, it can be frustrating if your electric bike isn’t working properly. If you own an electric bike, then you know that the controller is a key component of the bike.

The controller regulates the power going to the motor; your bike will not work correctly if it goes bad.

What is an Ebike Controller?

An Ebike controller is a type of electronic speed controller (ESC) that regulates the power output of an electric bicycle’s motor. It controls the bike’s speed and ensures it does not exceed the maximum speed limit.

The controller also has a throttle, allowing the rider to control how much power is being sent to the motor. If the throttle is not working correctly, it can be difficult to ride the bike.

It connects numerous sensors, the battery, the motor, the throttle, the display, and other components. It is a small computer that acts as the heart of the e-bike managing the overall functioning of the bike.

How to Reset Your Ebike Controller

There are several ways you can reset your ebike controller.

Use the C Settings on Your Controller

The most common way is to use the C settings on your controller. Here is a step-by-step guide on how to reset your ebike controller using the C-5 and C10 settings:

Step 1: Turn Battery On

You will not be able to reset the controller if the battery is not on. Make sure that the power switch is in the ON position before proceeding.

Step 2: Hold the Function Button

Locate the function button on the controller. This is usually a small black button. Once you have found it, hold it down for three seconds.

Step 3: Up and Down Buttons

Hold the up and down buttons for 3 seconds too. This is supposed to help you view and edit your default setting. The button will be on the side of the controller.

Step 4: Reset the P-Value

Once you see the P values on the screen, press and hold the up button until it says P0, this will reset the controller to its factory settings.

Step 5: Reset the C-Value

After the P value is set, muse the up and down to move to the C value, and move the C1 to C5 until it says C0. This will also reset the controller to its original state.

Step 6: Save Changes

Press and hold the function button for three seconds to save the changes that you have made. Your controller is now reset and should be working properly again.
