How Do I Reset My Ebike Controller? Solution

You’re cruising down the street on your bike, enjoying the wind in your hair and the sun on your face. Suddenly, without warning, your ebike comes to a screeching halt. The motor cuts out and you’re left coasting to a stop. What gives? It sounds like you may have a problem with your ebike controller.

Luckily, this is relatively easy to fix. In this blog post, we’ll walk you through the steps of how to reset your ebike controller so you can get back on the road in no time.

What is an Ebike Controller?

An ebike controller is a device that regulates the motor of an electric bicycle. It typically contains a battery, speed sensor, and control circuitry. The controller may also include an onboard computer, display, and user interface.

The battery supplies power to the motor. The speed sensor measures the rotational speed of the motor and sends a signal to the controller. The controller uses this information to regulate the power output of the motor.

The control circuitry consists of electronic components that regulate the flow of electricity to the motor. The onboard computer may be used to store data such as ride history, settings, and diagnostics.

The display shows information such as speed, distance, and battery level. The user interface allows the rider to input data and select options.

Why Would I Need to Reset My Ebike Controller?

If your ebike controller is not working properly, you may need to reset it.

Resetting your ebike controller can help fix issues such as:

-Ebike not responding to throttle input
-Ebike motor not working

 After 5 seconds, the controller should be reset and ready to go!

Step By Step guide to reset your E-bike controller.

If your ebike isn’t responding to input from the throttle or pedal assist sensors, it might be necessary to reset the controller. This is a relatively simple process that can be done at home with a few tools.

1. First, locate the controller on your ebike. It will be mounted near the battery and motor, and will have wires running to both.

2. Disconnect the negative (-) terminal from the battery. This will prevent any shocks while you work on the controller.

3. Using a Phillips head screwdriver, remove the screws that hold the controller in place. There should be four screws in total.

4. Carefully remove the controller from its mounting bracket, taking note of which wires go where. You may need to consult your ebike’s manual for this step.

5. Find the small reset button on the side or back of the controller unit (again, consult your manual if you’re unsure where this is).

6. Using a paperclip or similar object, press and hold the reset button for 3-5 seconds until you hear a beep from the controller unit. This indicates that the reset was successful.

7. Replace the controller in its mount, making sure that all of the wires are properly attached, and screw it in place with the four screws you removed earlier.

8. Reconnect the negative (-) terminal to the battery, and power on your ebike to test that the controller is functioning properly.

Tips for Maintaining Your Ebike Controller

Assuming you have an ebike with a motor controller, here are some tips for keeping it in good working order:

1. Keep the controller clean and free of debris. A build-up of dirt and grime can cause the controller to overheat or malfunction.

2. Inspect the controller regularly for any damage or wear and tear. If you notice any cracks or other damage, replace the controller immediately.

3. Make sure the wires connecting the controller to the battery and motor are securely fastened and in good condition. Loose or damaged wires can cause problems with the performance of your ebike.

4. Store your ebike in a dry, protected place when not in use. This will help to keep the components from corroding or being damaged by moisture.

5. If you are not comfortable working with electrical components, take your ebike to a qualified technician for maintenance and repairs.

With proper care and maintenance, your ebike controller should provide years of trouble-free performance. By following these simple tips, you can keep your ebike running smoothly and safely for many miles to come.

Electric Bike Parameter Settings and Meaning

Most electric bike controllers can be reset by pressing and holding a button for a few seconds. This will usually clear any error codes that may be causing problems.

However, if you’re not sure what the problem is, or if your controller doesn’t have a reset button, you can try changing the parameter settings. This may fix the problem without having to reset the entire system.

E-Bike letters & numbers.

There are a few things you need to know in order to reset your ebike controller. First, you’ll need to find the right letters and numbers for your specific controller. You can usually find this information in the manual that came with your bike. Once you have the right letters and numbers, you’ll need to input them into the controller.

To do this, you’ll need to first locate the tiny hole on the back of the controller. This is where you’ll insert a small tool, like a paperclip, in order to press the reset button inside.

Once you’ve found the reset button and pressed it, you should see a small LED light on the controller blink. This means that the controller has been successfully reset and is now ready to be used again.

Assuming you are referring to the P settings on an ebike controller, these settings stand for pedal assist. The higher the number, the more assist you will get from the motor while pedaling. For most people, it is best to start with P1 or P2 and work your way up as needed.

If you find that your motor is not providing enough assist, or if you are struggling to keep up with traffic, then you may want to increase the P setting. Conversely, if you find that the motor is providing too much assist and you are spinning out or going too fast, then you may want to decrease the P setting.

It is also worth noting that some controllers have a separate setting for throttle-only mode. This is typically denoted by a T (for throttle) instead of a P (for pedal). If your controller has this setting, it is best to leave it at its default value unless you are experienced with ebikes and know what you are doing.

P-Parameters P1 To P5

P1: This value, which looks at motor characteristics such as voltage, motor frequency, and performance under each of these values, means a lot for your motor.

Do not change this value unless you are qualified.

P2: This means the control for your Speed sensor if you’re not sure that your issue is with the sensor. It’s best to check the default value in the manual, though.

The P3 parameter typically controls your PAS or pedal assist levels. It usually has values from 0 to 5

If you set PAS to zero, then this will mean that the only intent is you need the system.

When using five as your throttle power, you will depend on the throttle power completely

P4: The throttle can be set to start automatically and has the values 0 or 1

Zero means that when the throttle is triggered, the motor will activate.

One: You’ll need to push the throttle in order for the electric motor to engage.

P5: This means that your controller will monitor the performance of your motor and battery.

The settings in this control should be changed, as if they are not set correctly then you won’t get accurate results about your battery.

a range of charging levels. (by default it will be set to 0 and this value will show the voltage mode you’re using).

C-parameters C1 To C14

C1: Check your manufacturing manual to set a throttle starting up.

C2 is your motor classification code, which is usually used if you have a scene wave drive motor.

C3 – Controls the power assist ratio gear, usually with values from 0 to 5

Zero: The motor only provides the slightest amount of help

Five: the highest pedal assist from the motor

C4: This parameter is being used to set the height of your electric bike handlebars.

C5: This parameter determines how much current your controller can handle. As we mentioned, you can use this as a way to reset your controller too. Please be aware that this may not work for some controllers so make sure to read the manual before trying anything.

C6: this parameter controls the backlit LCD display, which usually has five values from 1 to 5. One is the lowest brightness and five is the highest.

C7: cruise function settings (if your car has cruise) 1 for ON & zero to switch it OFF

C8: this parameter will show the motor temperature settings for the time in seconds

C9: Provide the setting for a password to use with your admin panel. No need to ever worry about forgetting your password again!

C10: It will reset all the settings to factory settings. You’ll need to contact the phone manufacturer for instructions on how to do this.

C11: The value for the ‘C11’ setting is typically from 0-2 and is used mainly to set the LCD’s attribute.

C12: this sets the minimum operating voltage (don’t change this)

C13: This parameter controls the ABS Anti-braking System.

C14: You can choose a power assist tuning setting that allows you to give more power to your ad, or less. The lowest is 1, and the highest is 3.

E-Bike common parameters that can be adjusted are:

-Motor current: This sets the maximum amount of current that the motor can draw. If it’s set too low, the motor may not have enough power to reach its top speed. If it’s set too high, the motor may overheat and shut down.

-Battery voltage: This sets the minimum voltage that the battery must maintain in order to keep the motor running. If it’s set too low, the battery will run out of power quickly. If it’s set too high, the battery may overheat and shut down.

-Controller temperature: This sets the maximum temperature that the controller can reach before shutting down. If it’s set too low, the controller may not work properly in hot weather. If it’s set too high, the controller may overheat and shut down.

-Speed limit: This sets the maximum speed that the motor can reach. If it’s set too low, the motor may not have enough power to reach its top speed. If it’s set too high, the motor may overheat and shut down.

-Power limit: This sets the maximum amount of power that the motor can use. If it’s set too low, the motor may not have enough power to reach its top speed. If it’s set too high, the motor may overheat and shut down.-Startup

current: This sets the amount of current that the motor will use when first turned on. If it’s set too low, the motor may not have enough power to reach its top speed. If it’s set too high, the motor may overheat and shut down.
-Battery capacity: This sets the maximum capacity of the battery. If it’s set too low, the battery will run out of power quickly. If it’s set too high, the battery may overheat and shut down.

-Maximum distance: This sets the maximum distance that the motor can travel before shutting down. If it’s set too low, the motor may not have enough power to reach its top speed. If it’s set too high, the motor may overheat and shut down.

-Maximum speed: This sets the maximum speed that the motor can reach. If it’s set too low, the motor may not have enough power to reach its top speed. If it’s set too high, the motor may overheat and shut down.


There are a few different ways to reset your ebike controller, depending on the make and model of your bike. However, the most common way is to simply disconnect and then reconnect the battery. This should cause the controller to reset itself and hopefully fix any issues you were having. If not, you may need to take it to a professional for further diagnosis.
