Xiaomiβs standard electric scooters are limited by the manufacturer in speed: 25 km/h for most models (M365, Pro 2, 1S) The new model is designed to be a 30 km/h flagship (Pro 3, 4 Pro) and it is not accidental that these restrictions are introduced, as they provide a balance between dynamics, safety and battery life. However, many owners want to get the most out of the equipment, especially if they drive on deserted roads or participate in competitions.
But before you start overclocking, it is worth understanding: any interference with the firmware or hardware of the scooter automatically deprives you of Xiaomi warranties and can lead to premature wear of components. 18650 or 21700, used in scooters, are not designed for long-term high currents - this is fraught with overheating and shortening the service life of the vehicle. 30-50%. In this article, we will discuss all ways to increase speed β from legal to extreme β and also explain how to minimize risks.
If you're a beginner, start with simple methods: tire pressure checks or firmware updates. Advanced users can consider custom software firmware or controller upgrades. The rule is, don't chase records at the expense of safety. Even when accelerating to the top. 40 km/h the stopping distance of the scooter increases in 2-3 time, and the grip on the asphalt deteriorates.
1. Legal ways to increase speed without interference with the equipment
Not all methods require breaking firmware or buying new parts. Start with these steps, they're free and don't affect warranty.
The first thing to check is the tire pressure. 35-40 PSI) Increases rolling resistance, making the motor work harder.optimal pressure for Xiaomi M365 β 50-55 PSI, pro 2/3 β 45-50 PSI. Use a pressure gauge and a pump with a thin hose (bicycle will not work - the scooter is smaller than the scooter nipple).
The second thing is the weight of the rider. Xiaomi scooters are designed to load up to the load. 100-120 If you're over this threshold, the motor will run at its limit and the speed will fall. Try to drive with a backpack on your back instead of a bag on the steering wheel - this shifts the center of gravity and improves dynamics.
- π Battery charge: At a charge level below 30%, the controller automatically limits power. Keep the charge above 50% for maximum speed.
- π‘οΈ Ambient temperature: At lower temperatures +10Β°C battery capacity drops on 20-30%, which reduces the peak power of the motor.
- π£οΈ Road cover: On gravel or wet pavement, the scooter loses up to 15% of its speed due to wheel slippage.
Also update the firmware of the scooter through the official Mi Home app. Newer versions often optimize engine control algorithms. For example, 1.5.4 firmware for the Pro 2 increased the smoothness of acceleration, which indirectly affected the top speed.
π‘
Warm up the battery before the trip 5-10 idling for minutes (keep the scooter on weight by pressing the gas) This increases the battery's return on the vehicle. 5-8%.
2.Configure driving modes through the Mi Home app
The official Mi Home app allows you to choose one of three driving modes:
- Eco-mode (Eco) β speed limit to 15-18 km/h, soft acceleration.
- Standard mode - up to 25 km / h, the balance between dynamics and power consumption.
- Sport mode (Sport) - maximum speed (up to 30 km / h for Pro 3), sharp acceleration.
The scooter is in Standard mode by default.
- Open Mi Home and connect to the scooter.
- Go to the Device. β Settings β Driving mode.
- Select Sport and save the changes.
In sports mode, the scooter accelerates faster, but the battery consumption increases by 25-30%, It also heats up the motor and the controller more, so avoid long trips at maximum speed.
What if there is no Sport option in the Mi Home?
Another hidden parameter β KERS (regenerative braking. Activation KERS Weak or Medium allows you to increase your speed slightly by the energy that goes back to the battery when you brake, but a strong recovery (Strong) can, on the contrary, slow down the scooter because of the increased resistance.
3. firmware custom software: risks and step-by-step instructions
The most radical way to overclock is to install an alternative firmware, for example, Custom Firmware (CFW) Or ScooterHacking Utility, which is a firmware that removes the manufacturer's limitations, allowing the scooter to accelerate to the scooter. 40-60 km/h (depending on model and battery) However, there are critical disadvantages:
- β‘ Loss of warranty β Xiaomi does not repair scooters with unofficial software.
- π₯ Controller overheating β standard components are not designed for high currents.
- π₯ Risk of fire - if the maximum current of the battery discharge is exceeded.
If you are prepared for risks, follow the instructions for firmware through ScooterHacking Utility (SHU):
Install the drivers. CP2102 controller|Download. SHU official website|Charge the scooter to 100%|Prepare. USB-cable (preferably original)|Make a backup of the current firmware
-->
- Connect the scooter to the PC through USB-port (located under the lid on the steering wheel).
- Launch it. SHU and select the model of the scooter in the menu.
- Go to the Firmware section β Read and save the current firmware (file with.bin extension).
- In the Firmware section β Write download custom firmware (for example, CFW_30kmh.bin ramp up 30 km/h).
- Wait until the process is over (about 5 minutes) and restart the scooter.
After you've done the firmware, check the brakes and the motor in a safe area, drive the first 10 kilometers in a gentle mode, so that the controller can adapt to the new settings, and if the scooter starts to twitch or spontaneously brake, go back to the stock firmware.
π‘
Custom firmware voids warranty and can cause a controller or battery to fail, and use this method only if you understand the risks.
4. Hardware modifications: controller, battery, motor
For those who want to dramatically increase speed, there are hardware upgrades.
| Modifications | The effect | Cost (β½) | Complexity of installation |
|---|---|---|---|
| Replacement of the controller by LYEN 18S | +15-20 km/h to maximum speed | 8 000 β 12 000 | Medium (swinging iron needed) |
| Installation of the battery 21700 50V | Increase in peak power by 30% | 15 000 β 25 000 | High (sweetening) BMS) |
| Motor upgrade (rewinding) | +10 km/h and improved acceleration | 5 000 β 10 000 | High (specialist) |
| Replacement of gear gear gear | Change in gear ratio (+5-10 km/h) | 2 000 β 4 000 | Medium |
The most effective replacement of the controller, LYEN 18S power-up 40A (against 18A squashing, which allows for the acceleration of M365 before 45-50 km/h, however, will require:
- π§ Re-sweeten the power wires from the battery to the controller.
- πΆ Set up parameters in the software (for example, VESC Tool).
- π‘οΈ Install additional cooling (radiator or fan).
When upgrading the battery, it is important to choose BMS (battery management system compatible with new elements, e.g. for assembly 21700 13S4P need BMS voltage-supported 54.6V current 30A+. Wrong choice. BMS It could cause a fire or explosion of the battery.
β οΈ Attention: Motor or controller modifications require electrical knowledge. Mistakes in soldering or tuning can short circuit and cause the scooter to fail. If you're not sure, call the technicians.
5. Weight optimization and aerodynamics: non-obvious life hacks
Even without interference with electronics, you can squeeze additional 2-5 And this is the one that actually works, and it reduces the air resistance and the weight of the scooter:
Weight loss:
- π² Remove unnecessary accessories: basket, trunk, additional headlights.
- π Replace the heavy lock with a lightweight cable (savings up to 300g).
- π οΈ Use aluminum pedals instead of plastic (minus 150g).
Improved aerodynamics:
- π Wear tight-fitting clothing instead of a loose jacket (air resistance decreases by a small amount of time). 10-15%).
- πͺ Attach to the steering wheel fairing made of plastic or carbon (you can make yourself from the bottle).
- ποΈ Get down when driving β this reduces the frontal area by 20%.
Also check the wheel bearings. Over time, they get clogged with dirt, which increases resistance. Take the wheels apart, wash the bearings in kerosene and grease them with Bones Speed Cream. 1-3 mile-long.
π‘
For maximum effect, combine all methods: firmware + upgrade + Weight optimization. For example, Xiaomi Pro 2 After such modifications, the 55-60 km/h, but requires reinforced brakes (e.g. hydraulics).
6. the risks of overclocking: what breaks most often
Increased speed inevitably leads to increased wear and tear of components, and here are the most vulnerable nodes and their typical breakdowns:
| Component | What's breaking | Reason. | Post-dispersal service life |
|---|---|---|---|
| Battery | Swelling of elements, loss of capacity | High discharge currents (>20A) | 6-12 months (instead of months) 2-3 years) |
| Controller | Power key burnout (MOSFET) | Overheating due to increased load | 3-6 months |
| Motor. | Wearing of brushes, melting of windings | Long-term high-speed work | 1-2 years |
| Brakes | Wiped pads, deformed disc | Increased braking distance at high speed | 3-4 months |
| Bearings | Luft, jamming. | Increased vibrations at speed >40 km/h | 6-8 months |
Especially dangerous is the thermal acceleration of the battery - a chain reaction in which the battery is heated to 100Β°C+, It's a gaseous gaseous gas, a problem:
- The scooter loses power through 5-10 minute.
- The battery body swells or hisses.
- The smell of the controller's burn.
β οΈ Warning: If the scooter starts to warm up stronger than usual after acceleration, immediately return the stock settings.Β°C (can be checked with an infrared thermometer) leads to irreversible damage to the battery.
To extend the life of the scooter after modifications:
- Install an external voltmeter to control the battery voltage.
- Use a thermal paste for the controller (e.g. Arctic) MX-4).
- Check the balance of the battery cells once a month (multimeter or BMS-monitor).
7. Alternative methods: tuning without loss of warranty
If you are not willing to risk the warranty but want to drive faster, consider these options:
1.Rent a powerful scooter
Services like Whoosh or Delimobil offer scooters with factory speed 35-40 km/h (e.g. Ninebot Max) G30). The cost of rent - from 200 β½/Plus: no risk to your Xiaomi.
2. Purchase of a factory-overclocked scooter
Some Xiaomi models are initially faster than the basic ones:
- π΄ Xiaomi Pro 3 β 30 km/h (factory restriction).
- π΄ Xiaomi 4 Pro - 32 km/h + brake-up.
- π΄ Xiaomi Electric Scooter 4 Ultra β 35 km/h and 768 Wh battery.
3. Use of external accessories
Some gadgets indirectly increase the speed:
- π Powerbank for scooter (for example, Scooter Booster) β connects parallel to the main battery, giving the power to the battery. +10% capacity.
- π Low resistance tires (e.g. Kenda) K1167) β Save up to 5% of energy.
- π¬οΈ Aerodynamic body kit - homemade or purchased fairings for the legs.
These methods will not give such an increase as firmware, but they are completely safe and do not affect the warranty.
