How to set the speed on the scooter Xiaomi: from firmware to upgrade

Xiaomi scooters are some of the most popular vehicles in the city, but factory speed limits (usually 20-25 km / h) often disappoint owners. Fortunately, there are several ways to increase the top speed, from software settings to hardware modifications. However, before you start to change, it is important to understand that accelerating a scooter above 30 km / h requires mandatory modernization of the brake system and protection, otherwise the risk of an accident increases significantly.

In this article, we will analyze all the current methods of adjusting speed on Xiaomi models. M365, Pro 2, 1S, 3/4 Lite and others, including:

• 🔧 Software methods (firmware, applications, custom firmware)
• ⚙️ Mechanical improvements (replacement of wheels, controller, battery)
• ⚠️ Risks and consequences (warranty, safety, wear and tear of parts)
• 📊 Comparison of methods on efficiency and complexity

Not all methods are equally safe: some can lead to loss of warranty, others to overheating of the controller or even fire, and we will indicate which changes are reversible and which require professional intervention.

Factory speed limits: why Xiaomi is blocking overclocking?

The manufacturer deliberately limits the speed of scooters for three reasons:

1. Safety: Most models are designed to ride on cycle paths, where the limit is 25 km / h.
2. Legislation: In the EU and Russia, there are regulations prohibiting scooters faster than 25 km / h without registration.
3. Battery and motor resource: High speed speed accelerates battery wear and increases the load on the controller.

For example, Xiaomi M365 In stock firmware, it accelerates to 25 km/h, and the Pro 2 to 28-30 km/h (depending on the region), while the real maximum speed is limited not only softwarely, but also mechanically: wheel diameter, gear ratio and motor power (250-350 W) do not allow to overcome the barrier of 35-40 km / h without modifications.

⚠️ Attention: Accelerating a scooter above 30 km/h without reinforced brakes (e.g. hydraulics) and protection (full-face helmet, knee pads) is extremely dangerous. Statistics show that 70% of scooter accidents occur at speeds above factory limits.

2. Software overclocking methods: firmware and applications

The most affordable way to increase speed is to change the settings through the official Mi Home app or custom firmware. Let's look at both.

Configure via Mi Home (official method)

In some regions (e.g. China), Xiaomi allows you to unlock speeds up to 30-32 km/h through the app.

1. Open Mi Home and connect the scooter.
2. Go to Settings. → Driving mode.
3. Choose Sport Mode (if available).
4. In some versions of the application, the Unlock Speed option will appear (requires confirmation on the application). SMS).

Note that this method does not work on all models and may disappear after a firmware update.

2.2 Castom firmware (CFW)

Alternative firmware is used for full speed control, such as:

• 🔄 ScooterHacking Utility (SHU) — for M365, Pro 2, 1S
• 🔧 DownG – Supports new models (4 Pro, 3 Lite)
• 🛠️ M365 BLE Tools – for fine tuning via Bluetooth

Firmware through SHU permitting:

• 📈 Increase speed to 40-50 km / h (depending on the model).
• 🔋 Disable battery power limit (e.g. driving to 0%).
• 🚦 Set up a throttle response (remove the delay at start).

Instructions for firmware through SHU:

1. Download ScooterHacking Utility from the official GitHub.


2. Connect the scooter to the PC via Bluetooth or cable (for older models).




3 Select a model in the program (e.g., "M365_BLE").




4. In the "Speed" section, set the desired limit (we recommend no more than 35 km / h for safety).




5. Press "Write" and wait until the scooter is completed (don't turn off!).

⚠️ Warning: The wrong firmware can brick the controller. Always back up the original firmware (Read before Write) and use stable versions of the software (avoid beta versions).

Download the latest version SHU GitHub|Check the battery charge (minimum 50%)|Keep the original firmware (backup)|Disable the antivirus (can block drivers)|Use a ferrite ring cable (for stable connection)-->

3. Mechanical modifications: what really works?

If software overclocking doesn't work, there are hardware improvements that require investment, but they increase not only the speed, but also the reliability of the scooter.

Replacement of wheels with larger diameter

Increasing the diameter of the wheels (for example, from 8.5 to 10) increases the top speed by 10-15% without changing the firmware.

• 🔄 10 inch slicks (e.g. Kenda) K193) — +3-5 km/h.
• 🛞 10 inch chubby tires (e.g, CST C1440) — better depreciation, but less speed gain.

Please note: the replacement of wheels requires lengthening of brake cables and possible modification of the wings.

Upgrade of the controller and motor

Xiaomi’s factory controller is limited in current (usually) 15–18 Replacement with custom (e.g. Votol) EM-150/200 on 30–40 (a) allows:

• 📈 Accelerate to 45-60 km / h (depending on the battery).
• 🔋 Improve acceleration (large torque).
• ⚡ Support more powerful batteries (e.g, 48V 20Ah).

However, such an upgrade requires:

• 🔧 Wiring soldering (cross section not less than 2.5 mm²).
• 🛡️ Installation of additional fuses (50-60 A).
• 🔥 Installation of cooling radiators (controller will warm up more strongly).

💡

Before replacing the controller, check compatibility with your scooter model. EM-150 fit M365 Pro 2, but not compatible with 1S flat-out.

4. Dispersal risks: what breaks most often?

Increased speed inevitably leads to accelerated wear and tear of components, and here are the most vulnerable nodes:

4.1. Battery.

At 35-plus acceleration+ km/h current consumption grows to 25-30 A, which leads to:

• 🔥 Overheating (especially when driving uphill).
• 📉 Reduced capacity (the battery "sets down" faster).
• ⚡ Risk of bloating (if) BMS high-current).

Solution: Use batteries with high-current cells (e.g. Samsung) 30Q or LG MJ1) Keep your temperature in check (optimally up to 50).°C).

Brake system

Xiaomi stock brakes (disc brakes) + electronic) not designed to be above 30 km/h:

• 🛑 Brake path increases by 1.5-2 times.
• 🔥 The pads and disc wear out for 500-1000 km (instead of 3000-5000 km in the drain).

Mandatory improvements:

• 🔧 Hydraulic brakes (e.g., Zoom) HB-100).
• 🛡️ 160 mm brake discs (instead of stock 140 mm).

⚠️ Attention: At 40 speed+ The stock electronic brake (recovery) becomes almost useless - its power is not enough for emergency braking.

5. How to check the real speed of the scooter?

The declared speed in the app often differs from the real speed. To accurately measure acceleration, use:

5.1. GPS-navigators

The most accurate method — GPS-tracker:

• 📱 Strava (records maximum and average speed).
• 🚀 GPS Speedometer (indicates speed in real time).
• 🗺️ Google Maps (in Bike Mode).

The margin of error GPS — 1–3%, depending on the number of satellites.

5.2 Bicycle computers

Devices like Xiaomi Mi Cycling Computer or Garmin Edge are mounted on the steering wheel and show:

• 📊 Current/maximum speed.
• 📈 Acceleration schedule.
• 🔋 Charge consumption per km.

Calibrate the wheel size in the settings for accuracy (for example, for 8.5" wheels, specify a circumference of 1650 mm).

💡

The speed in the Mi Home app is often overestimated by 5-10% due to the Hall sensor error. GPS erect.

Legal aspects: can you drive faster than 25 km/h?

In most countries, scooters are equated to bicycles, which means they are subject to the same restrictions:

• 🇷🇺 Russia: maximum 25 km/h (if exceeded - a fine of up to 1,500) ₽).
• 🇪🇺 EU: 25 km/h (in Germany up to 20 km/h on bike lanes).
• 🇺🇸 U.S.: Rules vary by state (California 28 km/h).

If you have a scooter up to 35+ q/h, legally it goes into the category of mopeds, which requires:

• 🆔 Registration in the traffic police (for Russia).
• 👮 Rights of category “M” (or B).
• 🚦 OSAGO insurance.

In practice, inspectors rarely stop scooters, but in case of an accident, the absence of documents can lead to a denial of insurance payments.

7. Alternative ways to increase speed without risks

If you don’t want to mess with firmware or mechanics, there are legal and safe ways to speed up a little:

• 🔋 Use "turbo mode": on some models (for example, Pro 2), holding the power button when turned on activates the mode with increased returns.
• 🛣️ Ride on flat asphalt: gravel or sand can reduce speed by 5-10 km / h.
• 🪠 Lubricate Bearings: Dirty Bearings Increase Resistance by 15-20%.
• 🧲 Check tire pressure: flat tires (2.0 bar instead of 3.5 bar) brake the scooter.

These methods give an increase of 2-5 km / h, but do not require intervention in the design.
