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 electronic speed controller (ESC) of the sort used in Ebikes is responsible for controlling the amount of energy delivered to the electric bicycle’s motor. It regulates the bike’s velocity so that it never travels faster than legally permitted.

The rider can adjust the amount of power sent to the motor via the throttle on the controller. To ride an Ebike with a faulty throttle is no easy feat.

It links things like a bunch of sensors, a battery, a motor, a throttle, a screen, and more. It’s a minicomputer that controls everything about the e-bike.

How to Reset Your Ebike Controller

You may reset your e-bike controller in a number of ways.

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

Without a charged battery, resetting the controller is impossible. Verify that the power switch is set to “ON” before continuing.

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

Additionally, press and hold the up and down arrows for three seconds. This is where you may go to see what your default settings are and change them if you want to. The controller’s side button will serve this purpose.

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.

Use a Software Program to Reset Your Controller

How to Reset Your Controller Manually
