Xiaomi Mi Electric Scooter M365 (or modification 365M) It's still one of the most popular vehicles in the city, but when you buy a used model, the main question is, how do you know the actual mileage? Vendors are not always honest, and you can drop the mile count on these devices in a couple of minutes. In this article, we will analyze all the current methods of mileage testing - from the official application to the hidden technical methods that use service centers.
The mileage of an electric scooter is not just a number on the display, it directly affects the battery, wear of bearings, braking system and even the safety of the ride. M365 It often requires replacement of brake pads, and after 15,000 km - check of bearings of wheels, so the ability to determine the real mileage will save you money and nerves.
We tested all of these methods in practice, and we identified 5 working methods, from simple to professional, some of which require only a smartphone, some require special equipment, and choose the right option depending on your ability and the degree of trust in the seller.
Why mileage on the display can lie: 3 reasons for cheating
Numbers on the Xiaomi screen M365 — It's just data from a controller that's easy to forge:
- 🔧 Reset via app. The Mi Home or Xiaomi Scooter has a reset function, just press the power button for 10 seconds and confirm the reset in the menu.
- 📱 Controller firmware, either with DownG or M365 Tools can reflash the device by zeroing out the mileage and even changing the serial number.
- 🔌 Some of the masters physically disconnect the sensor on the wheel so that the meter doesn't record miles.
Our tests show that more than 60 percent of the used scooters on the market have lost mileage, and even after zeroing, there are indirect indications that can be used to calculate real mileage, and this is discussed in the following sections.
⚠️ Warning: If the seller refuses to provide a scooter for diagnosis via Bluetooth or service menu, this is a reason to be wary%.
Method 1: Official Mi Home app (or Xiaomi Scooter)
The easiest method is to connect the scooter to a proprietary application, but it only works if the mileage has not been reset through the software.
- Download Mi Home (Android/iOS) Xiaomi Scooter (Android only).
- Sign up or sign in to your Xiaomi account.
- Turn on Bluetooth on your phone and scooter (hold the power button for 2 seconds).
- In the app, click Add Device → Electric scooter → Mi Electric Scooter M365.
- After connecting, go to the Statistics or Travel Data section.
Here you'll see:
- 📊 Total mileage (if not dropped).
- ⚡ Number of charges - an indirect indicator of battery wear.
- 🕒 Total time of use (in hours).
If the statistics are empty or the mileage is suspiciously low (for example, 50 km with visual wear), then the data is reset.
⚠️ Note: Mi Home only shows mileage if the scooter was tied to the account before the reset.If the seller untie the device, the data will disappear.
Compare the mileage with the visual state of the scooter
View the number of charges (more than 500 - critical battery wear)
Check the date of the first link to the account
Make sure that the serial number in the app matches the sticker on the frame-->
Method 2: Reading data via Bluetooth (advanced method)
If the mileage in the application is reset, you can try to get raw data directly from the controller via Bluetooth.
- Android smartphone (iOS does not support low-level access).
- The nRF Connect app (free on Google Play)
- Knowledge UUID services for Xiaomi M365.
Instructions:
- Open nRF Connect and connect to the scooter (the device will be called the scooter). BLE-MJ_...).
- Go to the Services tab and find the service with UUID 0000fee0-0000-1000-8000-00805f9b34fb.
- In this service, select the characteristic 0000ff02-0000-1000-8000-00805f9b34fb.
- Click Read and the data packet will be returned in hex format.
You can decode the answer with an online decoder, and the results will be a field. total_distance — This is the real mileage in meters. 123456 signifier 123.456 km.
| Field in hex packet | Meaning | What does it mean? |
|---|---|---|
| total_distance | 123456 | Range of 123.456 km |
| total_time | 36000 | Total driving time 36,000 seconds (10 hours) |
| battery_cycles | 250 | Number of complete charging cycles |
| firmware_version | 1.5.4 | Controller firmware version |
Important: This method works even if the mileage was reset through the application, since the data is stored in the controller’s non-volatile memory. However, some firmware (such as customized ones from DownG) can block access to this data.
💡
If nRF Connect fails to connect, try disabling other Bluetooth devices within a 5-meter radius, which can cause interference.
Method 3: Checking through the service menu (hidden mode)
Xiaomi. M365 There's a hidden service menu that shows you extended information, including mileage, to get into it:
- Turn off the scooter.
- Press the power button and the brake button at the same time.
- Hold for 5-7 seconds until the white light lights up.
- Release the buttons – the display will show the service menu.
The menu will show:
- 🔢 Total Mileage - total mileage (in km).
- 🔋 Battery Voltage – current battery voltage (healthy battery shows 42–43 V when fully charged).
- 🔄 Controller Temp: Controller Temperature (above 60)°C says wear and tear).
If the service menu mileage differs from the performance in the application, then the data was reset programmatically. Also pay attention to the firmware version (Firmware item) - if it is custom (for example, DownG). v2.1), It's a sign of interference.
⚠️ Attention: In some firmware, the service menu is disabled. If after 10 seconds of holding the buttons, nothing happens, then the controller is blocked.
What to do if the service menu is not opened?
Method 4: Analysis of wear of parts (visual diagnostics)
If the software methods didn't work, you should consider the physical wear of the scooter, and here are the key signs of a large mileage:
| Detail | Signs of wear and tear | Corresponds to the run. |
|---|---|---|
| Shina | Treads are erased, cord filaments visible. | 8 000+ km |
| Brake pads | Less than 2 mm thick, metal creak | 10 000+ km |
| Bearings | Luft wheels, extraneous sounds when rotating | 15 000+ km |
| Steering handles | Rubbing, cracking rubber. | 5 000+ km |
| Rama | Scratches on the folds, traces of repair welding | 20 000+ km |
Pay special attention to the battery:
- ⚡ If the scooter travels less than 15 km on a single charge (with a rider weight up to 70 kg), then the battery is worn out by 50% or more.+ km.
- 🔋 Bloating of the battery compartment - a sign of critical wear (20 000)+ mile-long).
For an accurate assessment of the battery condition, use a multimeter:
- Charge the scooter to 100%.
- Measure the voltage at the battery terminals (the connector under the seat).
- Compare it to the norm: 🟢 42.0–43.2 V – battery in good condition. 🟡 38.0-41.9 B - wear 30-50%. 🔴 Below 38.0 V - Requires replacement.
💡
If the visual wear of the scooter corresponds to the mileage of 15 000+ You can't buy a car, and the app says 500 kilometers, which is 100% cheating%.
Method 5: Diagnostics via diagnostic cable (for professionals)
The most reliable, but also the most difficult, method is to connect to the controller via a diagnostic cable.
- Cable USB-UART (for example, FT232RL).
- Putty or Screen (for the purposes of Linux/Mac).
- Screwdriver to disassemble the scooter.
Instructions:
- Remove the bottom cover of the scooter (4 screws).
- Find a connector on the controller board UART (4 contacts: GND, TX, RX, VCC).
- Connect the cable according to the scheme: Cable FT232RL → Controller M365 GND (black) → GND TX (white-coloured) → RX RX (green) → TX VCC (red) → 3.3V (not to connect unless you are sure!)
- Open Putty, select Serial, speed 115200.
- Turn on the scooter and send the command. AT+VER? link-check.
- For a mileage request, send AT+MILEAGE?.
The answer will be in the format:
+MILEAGE:125678
OKWhere 125678 - mileage in meters (125.678 km).
This method works even on custom-built scooters, as it addresses the microcontroller directly, but it requires soldering skills and risks losing warranty (if it still works).
💡
If you are not sure about your abilities, contact the Xiaomi service center - they can conduct a diagnosis for 500-1000 rubles. But warn that you need real mileage, not data from the application.
How to protect yourself from fraud: checklist before buying
In order not to run into a scooter with a twisted run, follow this algorithm:
Compare mileage in Mi Home and service menu
Verify data via nRF Connect (if you have Android)
Evaluate the wear of tires, brakes and bearings
Measure the battery voltage with a multimeter
Ask for a history of service (checks, photo repairs)
Make sure the serial number on the frame is not interrupted
Check the operation of all buttons and indicators-->
If at least one item is in doubt, it's better to drop the deal. - Xiaomi's average cost M365 with a run of 5,000 km - 12,000-15,000 rubles, and with a run of 20,000 km - 6,000-8000 rubles.
