Xiaomi scooters are some of the most popular vehicles in the city, but their high speed (up to 25-30 km / h) can be a problem for beginners, children or in dense traffic. Speed limiting not only improves safety, but also helps to comply with local traffic rules, where the maximum allowed speed for scooters often does not exceed 20-25 km / h.
In this article, we’ll take a look at all the speed limits available on Xiaomi’s M365, Pro, 1S, 4 Pro models, and more, from the official settings in the Mi Home app to hidden methods through firmware. You’ll learn how to temporarily slow down a child’s speed, set a hard limit for rent, or return factory settings if something goes wrong. And what Xiaomi models support dynamic speed limits based on the driver’s weight (a rare feature that few people know about).
1. Official speed limit via Mi Home app
The easiest and safest way to do this is to use the Mi Home app (or Xiaomi Home for new models), which works on all Bluetooth-enabled scooters, including the M365, Pro 2, 1S and 4 Pro. The main advantage is that you don’t have to disassemble the scooter or risk firmware.
To limit speed:
- Connect the scooter to the application via Bluetooth (press the power button for 3 seconds until the blue indicator flashes).
- Go to the Device section → Settings → Riding mode.
- Select one of the preliminary profiles: 🚶 Pedestrian mode (up to 6 km / h) - for driving on sidewalks or training. 🏃 Standard mode (up to 20 km / h) - optimal for the city. 🚀 Sport mode (maximum speed) – disables restrictions.
Save the settings - the scooter will reboot.
⚠️ Note: Some models (e.g. Xiaomi 4 Pro) have an additional Speed Limit for Kids option in the app that blocks switching modes without the need to use it. PIN-This is useful if the scooter is used by several people.

2. Manual speed limit through firmware (for advanced)
If the standard modes in the Mi Home are not enough, you can change the top speed at the firmware level. STM32-port and use of utilities such as DownG or ScooterHacking Utility. Suitable for models based on the controller STM32 (most of Xiaomi scooters).
Step-by-step:
- Download and install ScooterHacking Utility (works on Windows).
- Connect the scooter to the PC via a USB-TTL adapter (need TX, RX, GND wires). Connection circuit: Scooter (STM32) → TX adapter → RX RX → TX GND → GND
- Launch the utility, select the port and press Connect.
- Go to the Speed Settings section and set the desired limit (e.g. 18 km/h).
- Save the changes and restart the scooter.
Example of settings in M365 Tools:
- Connect the scooter to the application via Bluetooth.
- Go to the Settings → Speed Limit.
- Set a value (for example, 15 km/h) and save.
- Activate Lock Speed mode to prevent changing settings without PIN-code.
⚠️ Note: Third-party applications may conflict with official software. If after using them, the scooter begins to issue an error E014 (Firmware incompatibility, reset via Mi Home:
Settings → Reset to factory → Confirm

Mechanical methods of speed limitation
If software methods are not available (e.g., on older models without Bluetooth), mechanical limiters can be used:
| Method | Description | Pluses | Cons |
|---|---|---|---|
| 🔧 Adjustment of the brake pad | Pulling the brake cable to create permanent friction. | It does not require electronics, it works on any model. | Accelerates the wear of the shoe, can overheat the wheel. |
| 🔄 Installation of the smaller wheel | Replace the standard wheel (8.5) with 6" or 7" | Reduces speed by 20 to 30 percent without electronics. | It worsens the passability, can damage the suspension. |
| ⚙️ Use of a gearbox | Modification of gear ratio in the engine. | Constant restriction without dependency on the software. | It is difficult to implement, requires disassembly of the engine. |
💡 If you are temporarily limiting your child’s speed, use a bicycle computer with a limiter function (e.g., Sigma). BC It is mounted on the steering wheel and emits an audible signal when exceeding the specified speed.
5. Speed limit for rental scooters
If you're renting out a scooter, it's important to prevent it from accelerating to maximum speed.
- 🔐 Use it. PIN-code in Mi Home to block changes in settings.
- 📊 Set up geofences (if the scooter supports) GPS) — In some cities (for example, Moscow) rental scooters automatically reduce speed in pedestrian areas.
- 🔧 Set a physical limiter on the accelerator (for example, a rubber stop under the gas handle).
For Xiaomi Pro 2 and newer models, Parental Control is available in Mi Home, which allows:
- Set the speed limit remotely.
- Track the route and speed in real time.
- Block the scooter remotely when exceeding the limit.
💡
Xiaomi rental scooters (such as Whoosh or Delimobil models) often have a built-in limit of 20 km/h, which cannot be turned off software without access to the operator’s server.
6. Frequent mistakes and how to avoid them
With speed limits, users often face problems:
- The scooter does not save settings - check the firmware version (update via Mi Home) and repeat the procedure.
- After firmware scooter twitches - reset the settings to the factory or return the original firmware.
- The app doesn’t see the scooter – restart Bluetooth on your phone and scooter (press the power button for 5 seconds).
- Restriction resets after shutdown – activate Lock Settings mode in the settings.
⚠️ Note: Xiaomi scooters with firmware version 1.5.4 and higher may be affected by protection against unofficial changes. E030, execute:
Turn off the scooter for 10 minutes. Connect via Mi Home and reset the errors in the Diagnostics section. Update the firmware to the latest version.
