Buying a used Xiaomi electric scooter is always a risk of running into twisted mileage. It's not uncommon for vendors to drop meters through firmware or manipulate data in an app to increase the cost of machinery. But how do you tell honest mileage from fake? In this article, we'll look at all the ways of checking available, from official tools to engineering tricks that service centers use.
It's important to understand that Xiaomi's scooter mileage is not only recorded in the Mi Home mobile app, but also in the device controller, and in some models, in the battery memory, which means that even after being reset through the software, some of the data can be stored, and we will show you where to look for these "traces" and how to decrypt them.
The article is relevant for all popular models: Mi Electric Scooter Pro 2, Mi M365, Mi Essential, Mi 1S and others. Particular attention will be paid to methods that work even after flashing the controller - they are not known by all owners.
1. Run check through the official Mi Home app
The easiest, but also the most unreliable, way to look at the data in the Mi Home app, which shows total mileage, usage times and number of trips, but these numbers are easily reset by changing your account or reinstalling the program.
To access the statistics:
- π± Install the Mi Home app (available for Android and iOS).
- π Connect the scooter via Bluetooth (press the power button for 5 seconds before the beep).
- π Go to the Device section β Statistics.
- π Pay attention to the charts: sharp jumps or zeroing of data is a sign of twisting.
What should alert you:
- β οΈ Range less than 100 km with visually worn wheels or brake pads.
- β οΈ Lack of travel history in recent months (may mean resetting).
- β οΈ Date of first trip and condition of scooter (for example, "first trip - yesterday", but the scooter is clearly not new).
β οΈ Note: Mi Home is zeroed when you change your account region or link to another profile, and if a seller claims that the scooter is βvirtually newβ but canβt show your travel history, then youβre in doubt.
2. read data from the controller through the engineering menu
A more reliable method is to get information directly from the scooter controller, which is harder to forge because it's stored in the nonvolatile memory of the device, and you'll need special software to access it.
Tools required:
- π» Laptop or PC with Windows.
- π USB-Type-C Cable (to connect to the controller).
- π οΈ DownG or ScooterHacking Utility (you can download it on Xiaomi forums).
Step-by-step:
- Unscrew the screws on the bottom panel of the scooter and remove the lid (need a cross screwdriver).
- Find the USB connector on the controller (usually located next to the battery).
- Connect the cable to your PC and start the DownG program.
- Select Read Flash from the menu and wait for the data to be read.
- In the log, look for lines with Total Distance or Odometer parameters β this is the real mileage.
Warning: Not all versions of the controllers support reading through DownG. Newer models (such as the 2023 Mi Pro 2) may require an ST-Link programmer.

3. Analysis of wear of mechanical components
If software methods are not available, you can estimate the mileage by the physical condition of the scooter.
| Component | Signs of wear and tear | Approximate mileage |
|---|---|---|
| Tire (rubber) | Erased tread, cracks. | 1,000-1,500 km |
| Brake pads | Thinning to 1-2 mm | 800β1200 km |
| Wheel bearings | Luft, rotating noise | 1500+ km |
| Shock absorbers (if any) | Sitting, oil leaking | 2000 km+ |
| Steering handles | Erased coating, cracks. | 500β1000 km |
How to check:
- π Lift the scooter and scroll the wheels: if you hear a crunch or grinding - bearings worn out.
- π Press the brake lever: if the pads are almost not braked, their residual thickness is less than 20%.
- π Measure the tread depth of the tire: less than 1 mm means mileage from 1000 km.
β οΈ Warning: Some owners change their shoes or tires before selling to hide real wear.Always check multiple components at once.
How do I detect the change of details?
Checking through battery data (BMS)
In Xiaomi scooters from 2020 (starting with the Mi Pro 2), the mileage is partially recorded in the battery management system (BMS), which is not reset when the controller is flashed and can serve as an additional source of information.
How to get data:
- Download Battery Info (for Android) or CoconutBattery (for iOS).
- Connect the scooter to the phone via Bluetooth.
- In the battery menu, find the Cycle Count (number of charging cycles) and Full Charge Capacity (current capacity).
- Compare the current capacity with the passport (for example, for the Mi Pro 2 - 474 Wh). The capacity drop by 20% corresponds to a mileage of ~ 800-1000 km.
Formula of calculation:
Approximate mileage (km) β (Passport Capacity β Current Capacity) Γ 1000 / Passport Capacity Γ 15Where 15 is the average energy consumption per 1 km (depending on the model).
π‘
If the seller refuses to provide access to the BMS data, it may mean that the battery has already passed more than 300 charging cycles (mileage ~ 3000 km) and its capacity is critically low.
5. Alternative methods: service centers and online databases
If you're not sure about your abilities, you can turn to professionals. Some Xiaomi service centers provide a paid service for mileage diagnostics with the issuance of an official report, the cost is from 500 to 1500 rubles.
What's being checked on the service:
- π§ Controller status through diagnostic scanner.
- π Parameters BMS by means of specialized software.
- π Error logs that may indicate long-term operation.
There are also online databases where owners register their scooters, such as scooterstats.com, where you can enter a serial number (located under the battery) and find out the mileage history if the previous owner contributed data, but this method only works for 10-15% of devices.
β οΈ Attention: In Russia and the CIS, these bases are almost never used, and they are most relevant for scooters bought in the EU or the United States.
6.Signs of mileage twist: red flags for buyer
Even if the mileage in the app looks plausible, pay attention to these signals:
- π¨ Dates mismatch: Scooter released in 2021, first trip to Mi Home registered in 2023.
- π¨ Too "clean" story: No record of falls or errors (in reality, 90% of used scooters have them).
- π¨ Lack of branded packaging: If the seller claims that the scooter is βlike newβ but there is no box, instruction or charger, it is suspicious.
- π¨ Price below market by 20%+: Often it is a sign of twisting or other hidden problems.
What to do if you find a snare:
- Demand a discount (usually 10-30% of the market price depending on the actual mileage).
- Check other critical parameters: battery condition, backlash in bearings, brakes.
- If the seller refuses to meet, it is better to abandon the transaction.

The mileage cloth is not always a hoax. Sometimes owners reset the meter after a battery change or major repairs. Always specify the reason for the data zero.
