Xiaomiβs electric vehicle has gained popularity due to its excellent balance between price, quality and dynamics, but many owners face a situation where the standard maximum speed of 25 km / h seems excessive, especially when driving in dense traffic of pedestrians or on narrow sidewalks.
Limiting the acceleration potential is not just a matter of compliance, but also a way to extend the life of a battery and improve safety when driving in difficult weather conditions. In this article, we will discuss software and physical methods for lowering the speed limit.
It is worth noting that the standard Mi Home mobile application does not always provide direct access to fine restriction settings, so you often have to resort to third-party solutions or hidden system functions.
Why artificially reduce the maximum speed
The first thing to understand is why there is a need to damp the dynamics of acceleration. The regular βDriveβ mode on models like the Xiaomi Mi Electric Scooter Pro 2 allows you to reach speeds up to 25 km / h, which can be too fast for a beginner.
And you also use a lot more energy when you're driving at the limit, and if you want to drive the maximum distance on a single charge, lowering the speed limit is going to be an effective energy saving tool.
Safety is another key factor: In winter or rain, wheel grip drops, and abrupt acceleration can lead to skids, and forced restriction helps avoid emergencies.

In winter, it is recommended to reduce the speed to 10-12 km / h, since lithium batteries in the cold give less energy, and the braking distance increases by one and a half times.
There are several reasons for this setup:
- π¦ Teaching children or beginners to drive safely without the risk of abrupt acceleration.
- π Saving battery power to increase route autonomy.
- π§οΈ Improved safety when driving on wet asphalt or ice.
- π Compliance with strict local speed limits in park areas.
It is important to understand that the software restriction does not change the physical power of the motor, but only blocks the supply of maximum current to the windings.
Use of standard driving modes
The easiest and safest way to do this without third-party software is to switch driving modes, and you can have different profiles on the Mi Home app or on the scooter display.
Pedesterrian mode limits speeds to 6 km/h, which is ideal for walking, Drive mode is up to 20-25 km/h, and Sport removes some software limiters, but we need the first option.
To switch, you need to press the power button on the steering wheel twice, and the selected mode will appear on the display: P, D or S.
However, standard methods have a drawback: they do not allow you to set an arbitrary limit, for example, exactly 12 or 15 km / h.
β οΈ Warning: Switching modes on the go can lead to a sharp change in acceleration dynamics, which is dangerous in dense flow.
If the standard modes are not enough, you will have to use more advanced customization tools.
Setting limits through the ScooterHacking Utility app
For deep customization, Android device owners often use specialized software, such as ScooterHacking Utility, which allows you to interact with the BMS (battery management system) and the controller.
Once connected to the scooter via Bluetooth, you can find the settings in the settings menu that are responsible for the speed limit, often hidden flags or sliders in the engineering menu.
βοΈ Firmware preparation
The process is as follows:
- Launch the application and connect to the device.
- Go to the "Firmware" or "Settings" section.
- Find the item related to Speed Limit or regional settings.
- Set your desired value or select a region with stricter limits (e.g. Germany).
Changing the regional peg will often automatically reduce the top speed to 20 km/h or even lower, depending on the legislation of the country of choice.
After making changes, you must press the "Write" or "Save" button to save the configuration to the non-volatile memory of the controller.
Comparison of speed limiting methods
The choice of method depends on your technical skills and the desired result. Below is a table comparing the available methods.
| Method | Difficulty | Flexibility of setting | Risk of error |
|---|---|---|---|
| Pedesterian mode. | Low. | Only 6 km/h | Absent. |
| Change of region (EU) | Medium | Up to 20 km/h | Low. |
| ScooterHacking Utility | Tall. | Full (any meaning) | Medium. |
| Physical throttle | Tall. | Depends on the detail. | High-pitched |
As can be seen from the table, software methods through third-party utilities give the best result, but require caution.

Changing the region to the EU countries is the safest software way to legally slow down without complex hacking.
Physical methods, such as placing restrictive washers on a throttle cable, are used less often because of the risk of damage to the warranty.
The effect of speed limit on battery and mileage
The reduction in maximum speed directly affects aerodynamic drag and current consumption. At a speed of 15 km / h, energy consumption can be 30-40% lower than at 25 km / h.
This is because the electric motor is more gentle, heats less, and the controller is not experiencing peak loads, especially on the rises.
If you limit your speed, you can drive a longer distance on a single charge, which is critical for lower-range models like the Xiaomi Mi Electric Scooter Essential.
β οΈ Attention: Long-term driving at low speeds in "Sport" mode (if activated) is inefficient.
Itβs also worth noting that regenerative braking when driving smoothly works more efficiently, returning more energy to the battery.
Possible problems and solutions
The most common problem is that the scooter stops seeing the phone or shows an Error 10 error (communication with the controller).
If after setting the limits, the scooter behaves incorrectly (twitches at the start, stalls), you need to reset the settings to the factory or reflash the original firmware.
What to do if the scooter is blocked?
Always check the firmware version before making changes. Some new versions of Xiaomi software address vulnerabilities that allowed speed limits to be changed.
If you are not sure about your actions, it is better to limit yourself to standard modes so as not to lose the warranty on the device.
