Xiaomi electric scooters are some of the most popular vehicles in the city, but standard speed limits (25 For most models, km/h is often a disappointment to experienced riders. Fortunately, there are legal and illegal ways to increase top speed while maintaining battery life and safety. M365, Pro 2, 4 Pro, Electric Scooter 3/4 and others, including software tuning, upgrade of components and optimization of settings.
It is important to understand that any acceleration affects battery wear, braking system and legality of use (in most countries exceeding 25 km / h requires registration of the vehicle). We do not call for breaking the rules, but we will tell you how to increase the speed to 35-40 km / h with minimal risks to the equipment. All instructions are tested on firmware 2023-2026.
1. Software overclocking: firmware and custom firmware
The most common way to remove restrictions is to reflash the scooter controller, which requires special software (for example, DownG or ScooterHacking Utility), a cable. UART And a little patience:
- ๐ Remove the speed limit (up to 35-40 km / h depending on the model)
- ๐ Optimize battery efficiency (increase discharge current)
- ๐ ๏ธ Set up regenerative braking and throttle response
- ๐ Return the stock firmware at any time
For Xiaomi. M365 Pro 2 is good for firmware. CFW (Custom Firmware from the ScooterHacking community, newer models (4 Pro, Electric Scooter 3) will require DRV-Important: before you run the firmware, fully charge the battery and disconnect the scooter from the Mi Home app.
โ ๏ธ Warning: Incorrect firmware can incapacitate the controller. Use only verified versions of firmware from forums 4PDA or Reddit/r/ElectricScooters. If after firmware scooter does not turn on, try to reset the settings through the clamp of the power button on 10 seconds.
Step-by-step instructions for firmware through DownG:
- Download DownG and Drivers CP2102 for UART-adapter.
- Connect the adapter to the controller connector (see the location of the contacts in the documentation).
- Select the model of the scooter in the program and download the firmware file (.bin).
- Press Flash and wait until the process is completed. ~5 minutes).

2. Hardware tuning: replacement of the controller and motor
If software overclocking doesn't work, you can upgrade the hardware.
- ๐ง Controller: Replacement with Votol EM-150/200 or LYEN 6-FET allows for increased current to 30โ40A (vs. standard) 18โ22And).
- โก Motor: Installation of a brushless motor QS205 3T (800โ1000W) instead of stock (250โ350W).
- ๐ Battery: Replacement with Li-ion battery 48V 20Ah (For example, from Samsung. 50E).
For Xiaomi. M365 A complete replacement of the motor and controller will cost 15-25,000 rubles, but will accelerate to 50-60 km / h (subject to the installation of the appropriate battery), but such tuning requires soldering skills and an understanding of electrical circuits. For beginners, it is better to start with the replacement of only the controller - this will give an increase in speed by 10-15 km / h without serious alterations.
| Component | Model for upgrade | Speed increase | Cost (โ) |
|---|---|---|---|
| Controller | Votol EM-150 | +5-10 km/h | RUB 8,000-12,000. |
| Motor. | QS205 3T | +15โ20 km/h | 10-15 thousand rubles. |
| Battery | 48V 20Ah (Samsung 50E) | +20-30 km/h (with motor) | 18-25,000 rubles. |
| Wheels. | 10" slicks (Kenda) | +2-5 km/h (due to reduced resistance) | 3-5 thousand rubles. |
โ ๏ธ Attention: Replacing the motor with a more powerful one requires mandatory brake upgrades. Xiaomi stock brakes are not designed for speeds above 35 km / h. Install at least hydraulic discs (for example, Zoom). HB-875) or magnetic brakes for safety.
3. Optimization of settings in the Mi Home application
Even without firmware, you can slightly increase the speed through the official Mi Home app.
- Open the app and connect to the scooter.
- Go to Settings. โ Driving mode.
- Choose Sport (if available) โ this increases the engineโs output by 10-15%.
- Turn off energy saving and regenerative braking (if not necessary).
For Pro 2 and later, you can find the Maximum Speed option in the Additional Settings menu, which is blocked in some regions (e.g. EU), but you can unlock it through the Mi Home with a changed region (e.g. Singapore or Russia).
๐ก
If your region has a blocked speed limit, try changing the country in your Mi Home profile to Taiwan or Hong Kong โ there are often advanced settings available.
It is also worth calibrating the throttle (gas):
- Turn on the scooter.
- Press the power button. + brake.
- Release and press the gas to the point โ the controller will remember the maximum position.
4. Upgrade of wheels and suspension
Speed depends not only on the motor, but also on rolling resistance, and replacing the wheels with slicks (smooth tires without tread) can give you an increase of 2-5 km / h by reducing friction.
- ๐ฒ Kenda K103 (10) - lightweight and wear-resistant.
- ๐ด CST C1430 โ soft, well-depreciated.
- โก Maxxis Hookworm โ for extreme skating (but wears out quickly).
Also, you should pay attention to the pressure in the tires:
- ๐น 2.5-3.0 bar โ optimal for speed (hard driving).
- ๐น 1.8โ2.2 bar โ more comfortable but slower.
For models without depreciation (e.g, M365) You can put spring shock absorbers like Monorim or rubber dampers under the platform, and it doesn't increase the speed directly, but it allows you to keep the pace up on rough roads.

5. Battery tuning: increased voltage and capacity
Xiaomi Standard Batteries (36V or 48V) There are two advantages to replacing a more powerful battery with a maximum speed limit:
- Higher discharge current โ speed up.
- Increased range โ You can drive at high speed longer.
The best options for upgrade:
| Model battery model | Tension. | Capacity | Speed increase |
|---|---|---|---|
| Samsung 50E 18650 | 48V | 20Ah | +5-8 km/h |
| Panasonic NCR18650GA | 36V | 15Ah | +3-5 km/h |
| LG MJ1 21700 | 52V | 24Ah | +10-12 km/h (requires a new one) BMS) |
To install a new battery will require:
- Disassemble the body of the scooter (you need a cross screwdriver and plastic shoulder blades).
- Disconnect the old battery while retaining the connectors BMS balancer.
- Connect a new battery to ensure the correct polarity.
- Check the voltage with a multimeter before the first switching on.
โ ๏ธ Warning: Batteries with higher voltage 48V require replacement BMS-(Battery management system) use of incompatible BMS Buy batteries only from trusted sellers (e.g. AliExpress rated 98%+).
6. Alternative methods: weight, aerodynamics and driving style
Even without technical improvements, you can go faster, optimizing external factors:
- ๐๏ธ Rider weight: The lighter the driver, the higher the top speed. The difference between 60 kg and 100 kg can reach 3-5 km / h.
- ๐ฌ๏ธ Aerodynamics: At speeds above 30 km/h, air resistance becomes critical. Sit down or use a windscreen (e.g. from a bicycle helmet).
- ๐ฃ๏ธ Road cover: Asphalt can be 10-15% faster than gravel or grass.
- ๐ Acceleration from place: Smooth pressing of gas (without jerks) allows you to quickly gain maximum speed.
Also, you should pay attention to the ambient temperature:
- ๐ฅ Primary +25ยฐC and above the battery gives maximum power.
- โ๏ธ At least 10.ยฐC speed can drop by 10-20% due to reduced capacity of Li-ion batteries.
๐ก
The cheapest way to speed up is to reduce the weight of the scooter, remove the extra accessories (basket, trunk), use lightweight wheels and a carbon platform (if available for your model).
7. Risks and legal aspects
Exceeding speeds above 25 km/h in most countries (including Russia and the EU) is equivalent to driving a moped, which requires:
- ๐ Registration of the vehicle in the traffic police (or local analogue).
- ๐ฎ Rights of category M (or B).
- ๐ฆ Compliance with traffic rules (including helmet, lighting devices).
In case of an accident or stop by an inspector, you can be fined (in Russia - from 5 to 15 thousand rubles for not registering).
- ๐ฅ Loss of control (especially on wet roads).
- ๐ Battery overheating (fire risk).
- ๐ ๏ธ Rapid wear of bearings and motor.
If you still decide to disperse the scooter, follow the rules:
- ๐ช Use full equipment (helmet, elbow pads, knee pads).
- ๐ฆ Only ride on bicycle lanes or empty streets.
- ๐ง Check brakes and tire pressure regularly.
