Xiaomi scooters have long been synonymous with affordable and reliable urban electronics. But how long will your electric scooter last? The answer depends on many factors: model, operating conditions, even driving style. In this article, we will understand what the real resource of the key components — battery, motor, suspension — and how to maximize it.
Many users mistakenly believe that the life of the scooter is limited only by battery power. In fact, wear affects all nodes, from brake pads to electronic controllers. We analyzed manufacturer data, owner reviews and test results to give a clear answer: how many kilometers or years will your Xiaomi M365, Pro 2 or 4 Ultra last in different use cases.
Spoiler: With proper operation, even Xiaomi’s budget models can travel 10,000-15,000 kilometers without major repairs, but there are nuances that the manufacturer does not mention.
1. Battery Resource: How many charging cycles will the battery withstand?
The battery is the most expensive and vulnerable component of the scooter. Xiaomi models use lithium-ion batteries with a nominal life of 500-800 full charge cycles. But what does this mean in practice?
One cycle is a 100 to 0% battery discharge and a reverse charge. If you use 50 percent of your charge every day, technically it's a 0.5 cycle. ~8000-12,000 km of mileage for most models).
However, there are some critical factors that shorten battery life:
- 🔥 Overheating: charging at temperatures above 35°C or sun storage accelerates degradation by 30-40%.
- ⚡ Deep discharge: if you leave the scooter discharged for a few days, the battery can lose up to 20% of capacity.
- ❄️ Freezing storage: at -10°C and below lithium-ion cells lose up to 50% of their capacity in winter.
The manufacturer claims that the battery retains 80% capacity after 500 cycles, but in practice this figure often decreases to 60-70% due to imperfect conditions. For example, the Xiaomi M365 after 2 years of intensive driving, the real capacity drops to 50-60% of the original.
⚠️ If the scooter suddenly begins to lose charge by 10-15% per night (when switched off), this is a sign of degradation of the controller. BMS It's dangerous to run a device like this, or short circuit in cells!
Motor and transmission: when to wait for replacement?
Xiaomi’s electric scooters use brushless motors (BLDCs) with a life of 15,000-20,000 km under normal conditions, but the actual lifespan depends on three factors:
Load: If the weight of the rider exceeds 100 kg (or the scooter is often overloaded), the bearings and windings of the engine wear 2-3 times faster. For example, the Xiaomi Pro 2 with a user weight of 120 kg, the engine life is reduced to 8000-10 000 km.
Driving conditions: frequent driving on sand, dirt or puddles leads to the entry of abrasive particles into bearings, which causes a backlash shaft and increased noise, in advanced cases, the motor can jam.
Build quality: Budget models (e.g., M365) use 608ZZ class bearings that require replacement every 5,000–7,000 km. In premium versions (e.g., 4 Ultra) are reinforced 6902RS bearings with a life of up to 15,000 km.
| Model scooter | Motor type | Engine resource (km) | Bearing resource (km) |
|---|---|---|---|
| Xiaomi M365 | 250W BLDC | 10 000–12 000 | 5 000–7 000 |
| Xiaomi Pro 2 | 300W BLDC | 12 000–15 000 | 7 000–10 000 |
| Xiaomi 4 Ultra | 700W BLDC (dual) | 18 000–20 000 | 12 000–15 000 |
Signs of engine wear:
- 🔊 Increased noise or grinding when dispersed.
- 🔥 Overheating of the motor body (more than 60)°C after 10 minutes drive).
- ⚡ 10-15% drop in maximum speed when fully charged.
3. Suspension and wheels: what breaks first?
The suspension and wheels are the "consumers" that wear out the fastest. In non-depreciation models (such as the M365), the front fork and rear shock absorber (if any) are the main loads.
Front fork: bushings and glands wear out after 3000-5000 km When driving on uneven roads (kerbs, pits) this period is reduced to 2000 km.
Rear shock absorber (in models with rear suspension): loses efficiency after 5,000-7000 km. Spring sags, and the damper stops extinguishing the impacts. In Xiaomi Pro 2 and 4 Ultra shock absorber lasts longer due to the reinforced design.
Wheels: tires wear out from 1,500 to 3,000 km (depending on driving style); tubeless tires (Xiaomi 4 Ultra) are more durable but harder to repair; Cameras (M365) are more likely to pierce, but cheaper to replace.

Electronics: controller, sensors and display
Electronic components rarely fail suddenly, but their resource is limited.
Controller (ESC): Controls the engine power and brakes, which averages 10,000-15,000 km, but can burn up earlier due to:
- ⚡ Short circuit (for example, when water is ingested).
- 🔥 Overheating (if the scooter works at maximum power for a long time).
- 🛠️ Incorrect repairs (for example, soldering wires without insulation).
Speed and brake sensors: hallucination sensors (in wheels) wear out for 5,000–8,000 km. Their malfunction leads to jerks during braking or false positives.
Display: Budget models (M365) often leave the plume or burn out pixels after 2-3 years of use. 4 Ultra uses a more secure screen, but it is not eternal either.
⚠️ Attention: If the scooter starts to spontaneously brake or twitch when accelerating, this may be a sign of a malfunction of the Hall sensor in the engine!
5. How to extend the life of the Xiaomi electric scooter?
Compliance with several rules will help to increase the life of the scooter by 30-50%:
Battery:
- 🔋 Charge the battery at a temperature of 10–25°C.
- 🔌 Do not leave the scooter on charging for more than 4-5 hours.
- 📉 Calibrate the battery once every 3 months (full discharge) → full-load).
Motor and transmission:
- 🛑 Avoid sharp starts and braking.
- 🧹 Clean the engine from dirt every 1,000 km (use compressed air).
- 🔧 Check the bearings once every 5,000 km.
Suspension and wheels:
- 🚲 Maintain tire pressure (2.5-3.0 bar for most models).
- 🔧 Lubricate the sleeves of the fork once every 2,000 km.
- 🛡️ Install protective spray guards if you drive on wet roads.
💡
After raining or washing the scooter, be sure to dry it for 2-3 hours at room temperature. Humidity inside the case can cause corrosion of the controller contacts.
6 When is it time to change the scooter and when is it time to repair it?
The decision to repair or replace depends on the cost of work and the condition of key sites.
Repairs are justified if:
- 🔋 Replacement of the battery (cost) ~30-50% of the price of a new scooter).
- 🛠️ Worn bearings or tires (cheap repairs).
- 📱 Display or controller is not working (if the rest of the nodes are in order).
A substitution is justified if:
- 🔥 The engine or controller burned (repair will cost 60-80% of the price of a new scooter).
- 💀 The body or frame is deformed (for example, after an accident).
- ⚡ The battery has lost more than 50% of capacity, and its replacement is impractical (for example, in outdated models).
For example: repair Xiaomi M365 Replacement of the battery and bearings will cost ~15 000–20 000 ₽, while the new scooter is standing ~25 000–30 000 ₽. If you want to replace the motor and the controller, it's cheaper to buy a new model.
