How to increase the speed of Xiaomi M365 Pro: Safe acceleration without loss of resource

Xiaomi Electric Scooter M365 Pro became a hit among urban vehicles due to the balance of price, quality and technical characteristics. However, many owners after a few months of operation begin to notice that the standard 25 km / h limit the capabilities of the device - especially at long distances or when driving on highways. In this article, we will discuss legal and illegal ways to increase speed, their effect on the battery and engine, as well as the risks that are important to consider before modifying the device.

Before proceeding with the acceleration, it is worth understanding: M365 Pro is originally programmed to limit speed not only because of the legal regulations (in most countries of Europe and Russia the limit is not limited — 25 km/h), but also to save battery life and motor life. 30% and reduces the battery life by 20-40% However, if you're willing to compromise, then you'll have step-by-step instructions with nuances for each method.

1. Software overclocking through firmware: pros and cons

The most popular way to increase speed is to reflash the scooter controller, which allows you to remove factory restrictions without physical changes in design.

• 🔹 Xiaomi’s official updates (rarely increase speed but improve stability).
• 🔹 Community firmware (e.g. DownG or ScooterHacking Utility).
• 🔹 Modified BMS-Firmware (affects battery management).

You'll need firmware.

• 🖥️ Windows computer 10/11 (MacOS is not supported by most utilities).
• 🔌 Cable USB-TTL (for example, FT232RL).
• 📥 ST-Link Utility or Flash Tool.
• 🔋 Charge at least 50% (to avoid shutdown during the process).

The firmware process takes 10-15 An error in the selection of a firmware file or interruption of the process can lead to the "bricking" of the controller. M365 Pro - before 30-32 Exceeding this threshold leads to overheating of the engine and the risk of fire of the battery.

⚠️ Note: Firmware lifting restrictions will void the warranty Xiaomi. in case of failure of the controller or battery repair will cost in the future. 30-50% cost of new scooter.

2. Hardware modifications: what really works

If software overclocking fails to produce the desired result, owners resort to hardware improvements, and here are the most effective (and proven) ways to do this:

The best-balanced option is to replace the gear, which increases speed without critical battery loads.

1. Remove the rear wheel and gearbox.
2. Dismant the standard gear (16 teeth).
3. Install a new (14 teeth) using thermal glue or epoxy resin.
4. Calibrate the brake disc (if necessary).

Remove the wheel and clean the gearbox from dirt

Prepare a new gear (14T) heat-glue

Check compatibility with the braking system

Have spare bolts on hand (M5×12 mm)

-->

Once the gear is replaced, the scooter will accelerate faster, but the top speed depends on the firmware. If the controller is programmed to 25 km/h, the physical modification will only increase to this limit. So hardware improvements are usually combined with firmware.

3. Optimizing the battery to improve performance

Battery is a key factor in speed, even with factory settings. M365 The Pro loses up to 15% power at a discharge below 40% to maintain maximum return:

• 🔋 Use only the original zoo (54.6V/1.5A). Cheap analogues reduce battery life.
• 🌡️ Avoid charging at a temperature below +5°C or higher +35°C.
• 🔄 Once every 3 months, perform a full discharge / charging cycle (0)→100%) for calibration BMS.
• 🛠️ Clean the battery contacts with alcohol every 6 months (oxidation increases resistance).

If the battery has already lost capacity (the scooter travels less than 30 km on a single charge), it can be restored by replacing the faulty elements.

1. Disassemble the battery unit (a soldering iron and tester are required).
2. Check the voltage on each bank (normal: 3.6–3.7V).
3. Replace the cans with voltage below 3.2V.
4. Re-drink. BMS with the new number of elements.

⚠️ Warning: Unleashing a battery without experience can be short-circuited. Work with gloves and use isolated tools. In 2023, there were 12 cases of Xiaomi scooters catching fire after homemade battery repairs.

💡

Before a long trip, warm up the battery. 5-10 Minutes at low speeds – this increases the return on 8-12% due to the optimal temperature of the electrolyte.

Tyre pressure and suspension setting

What many people don't realize is that rolling resistance has a direct impact on speed. M365 Pro used tubeless tires 8.5" pressure-recommended 35-40 PSI. However:

• 🚀 Under pressure 45-50 PSI speed up 1-2 km/h by reducing the contact spot.
• 🛑 Pressure below 30. PSI Scooter "sticks" to the asphalt, losing up to 15% of power.
• ⚠️ Exceeding 55 PSI Risk of a tire exploding when hitting an obstacle.

For fine tuning:

1. Use a gauge with no more error ±1 PSI.
2. Check your blood pressure every 2 weeks (the rubber gradually poisons the air).
3. For winter driving, reduce the pressure by 5 PSI better-clutch.

Also worth paying attention to is suspension. Hard shock absorbers like Monorim reduce rocking at high speeds, but transmit more vibrations to the steering wheel. The best option for high-speed driving is to replace the springs with polyurethane stiffness. 80A.

5. Engine tuning: when the standard is lacking

Standard engine M365 Pro has power 300W (peak — 600W). To accelerate to 35.+ That's not enough:

• 🔧 Rewinding the stator (increases power to 800W, but requires lathe work).
• 🔄 Replacement with a brushless motor (e.g, QS205 800W).
• 🧲 Installation of neodymium magnets (increases torque by 20%).

The most budgetary option is to rewind. It'll cost you a lot. 3 000–5 000 ₽ and add 30-40% But after the modification:

• 🔥 The engine will warm to the ground. 80-90°C (standard limit — 65°C).
• 🔋 Current consumption will increase by 30%, reducing battery life.
• 🛠️ Replace thermopaste every 3 months.

To install a brushless motor will have:

1. Remove the standard motor and gearbox.
2. Install a new motor with an adapter for fastening.
3. Connect phase wires to the controller (observing polarity!).
4. Calibrate Hall's sensor.

6. Alternative methods: when acceleration is inappropriate

If your goal is not to race, but to drive at a slightly higher speed, consider the alternatives:

• 🚲 Replace the wheels with 10" (increases clearance and speed by 1-2 km/h).
• 🪑 Installation of aerodynamic fairing (reduces wind resistance by 5-7%).
• 🔄 Use of the "Sport" mode (in some firmwares unlocks) +2 km/h).
• 🧴 Bearing lubricant (reduces friction by adding) 0.5-1 km/h).

In Russia, according to the traffic rules of paragraph 24.8, the maximum speed for scooters is 25 km / h. Exceeding the risk of a fine of up to 2 000 ₽ (In some regions, up to 5,000 ₽). It is possible to increase the speed legally:

• Design a scooter as a moped (PTS, category M rights are required).
• Use a scooter only on closed areas (for example, karting tracks).

💡

Any acceleration over 25 km/h makes it illegal to drive on public roads, risks: fines, confiscation, problems with insurance in accidents.

7. Service after acceleration: how to prolong the life of a scooter

After any modifications to Xiaomi M365 Pro requires more frequent maintenance. Minimum checklist:

Pay special attention to the braking system. At speeds above 30 km/h, standard brakes M365 Pros are becoming under-performing.Recommended upgrades:

• 🔧 Installation of hydraulic brakes (e.g. Magura) MT4).
• 🛡️ Replacement of brake discs with perforated (it is better to remove heat).
• 🔄 Setting up ABS (if supported by firmware).

Also, don't forget about insurance: in 2026, there were 127 scooters in Russia, 43 of them fatal, and at speeds above 30 km / h, it is recommended:

• Use a full-face helmet (for example, LS2 Stream).
• Install rearview mirrors.
• Wear protection for the back and knees.
