This is a very common question among e-bike riders, and in most cases, it is not a malfunction. Instead, it usually relates to how the display is designed to show different types of mileage data.

This article explains how e-bike odometers work, why the mileage may appear to reset, and how to correctly switch between trip mileage and total mileage.

Understanding How E-Bike Mileage Displays Work

Most E-Bikes are equipped with a digital display that records two different types of mileage:

TRIP – Distance of a single ride

ODO – Total accumulated mileage of the E-Bike

Confusion often occurs when riders mistake trip mileage for total mileage.

1. Default Display: Single Ride Mileage (TRIP)

When the E-Bike is powered on, the display defaults to showing the mileage of the current ride.

This means:

The number you see represents only the distance traveled during that ride

It does not represent the lifetime mileage of the E-Bike

This is normal behavior and is designed to help riders track individual trips, such as daily commutes or exercise rides.

2. Why Does the Mileage Reset to Zero?

The single ride mileage (TRIP) is designed to reset automatically.

Specifically:

When the E-Bike is powered off, the TRIP mileage resets to zero

When you power the E-Bike back on, a new trip starts

This can give the impression that the odometer is not recording distance correctly, but in reality, only the trip counter is resetting.

The total mileage (ODO) is not affected by powering the E-Bike on or off.

3. How to Switch Between TRIP and ODO Displays

To view the correct mileage information, you can manually switch the display mode.

Steps to change the mileage display:

Turn on the E-Bike

Press the "M" button three times

The display will cycle between:

TRIP – single ride mileage

ODO – total accumulated mileage

Once ODO is displayed, you will see the full distance the E-Bike has traveled since it was first used.

Common Reasons Riders Think the Odometer Is Incorrect

In most cases, the display is working exactly as intended. Common misunderstandings include:

Assuming the default TRIP mileage is total mileage

Not realizing TRIP resets after powering off

Not switching to ODO mode using the "M" button

Actual odometer faults are relatively rare.

When Should You Be Concerned?

You should consider contacting customer support or service if:

The ODO mileage does not increase at all during rides

The display does not respond when pressing the "M" button 

The mileage resets even when set to ODO

The display shows abnormal symbols or error codes

In these cases, the issue may be related to the display unit, speed sensor, or wiring.

Conclusion

If your E-Bike's odometer display seems incorrect, it is usually due to the display being set to TRIP (single ride mileage) rather than ODO (total mileage).

To summarize:

The default display shows single ride mileage

Single ride mileage resets when the E-Bike is powered off

Press the "M" button three times to switch between TRIP and ODO

Understanding this distinction will help you accurately track your riding distance and avoid unnecessary concerns about your e-bike's performance.
