How to disassemble the electric scooter Xiaomi: instructions for models M365, Pro, Essential and others

Xiaomi scooters are some of the most popular vehicles in town, but even they require maintenance. Over time, you may need to clean the bearings, replace the camera or battery with a punctured one, and sometimes diagnose electronics after a fall. Disassembling the scooter seems like a challenge, especially if you've never held a hexagon screwdriver in your hands. However, with the right approach, the process takes less than an hour and requires no professional skills.

In this article, you will find step-by-step photo instructions for disassembling all key components: wheels, steering column, battery and electronics. We will also tell you what tools you will need, how to avoid typical errors (such as damage to wires) and what to do if the scooter does not turn on after assembly.

If you've never repaired a machine, start with a simple one: removing the wheel or the battery cover, which will help you understand the design and avoid the annoying errors when dealing with more complex nodes, and if the scooter is still under warranty, remember that unauthorized disassembly will void warranty obligations.

What tools will be needed to disassemble

Without the right tool, it's almost impossible to disassemble a Xiaomi scooter -- standard screwdrivers won't help here. Here's the minimum set you'll need for most operations:

• 🔧 Hexagons (dimensions 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm) - for steering gears, brakes and footrests.
• 🔨 torks T20 and T25 — for battery compartment screws and electronics (in new models, for example, Pro 2 or 4 Pro).
• 🔧 Cross screwdriver PH2 — for certain plastic covers and headlamp anchorages.
• 🛠️ Flat screwdriver or mediator - for careful removal of clips and plastic panels.
• 🔧 Dynamometer key (optional) - for precise tightening of bearings and steering column (the moment of tightening is usually 40-60 N).
• 🧲 Magnetic pallet or tray - so as not to lose small screws and washers.

For specific tasks, you may need:

• 🔧 Removal of bearings – if you plan to replace them.
• 🔧 soldering iron – for repair of wiring or controller (only if you have experience!).
• 🧴 WD-40 or similar to the one that is used to remove rusty or boiled bolts.

⚠️ Warning: Do not use percussion tools (hammer, chisel) to unscrew the bolts, this will deform the thread and can damage the frame. If the screw does not respond, moisten it. WD-40 and wait 10-15 minute.

For Xiaomi models M365 And Pro will fit the standard set of hexagons, but Pro 2 and newer will require torxes.

Preparation for disassembly: safety and organization of the workplace

Before you start to use the tools, prepare the space and the scooter itself, and this will save you from losing parts, short circuits and injuries.

1. Choose a flat surface – a table or workbench, covered with cloth or rubber mat (so that the details do not roll).
2. Turn off the power – remove the battery or disconnect the battery connector from the controller (if you do not plan to work with the electrician, just remove the battery).
3. Take a picture of the original state -- especially the location of the wires and connectors -- and that'll help with the reverse assembly.
4. Prepare containers for parts – use small boxes or packages with labels ("rule screws", "wheel mounts", etc.).

If you are disassembling a scooter for cleaning, prepare in advance:

• 🧼 Soap solution or special means for cleaning equipment.
• 🧽 Soft brush (for example, toothbrush) for bearings and hard-to-reach places.
• 🌬️ compressor or cylinder for purging.

⚠️ Warning: Never wash a scooter under a stream of water - moisture will get into bearings, electronics and battery, which will lead to corrosion or short circuit. Use only a wet cloth and brushes.

In Xiaomi models with a system KERS (Regenerative braking, when the battery is turned off, there may be a voltage in the capacitors of the controller. 10-15 minutes after power outage to avoid electric shock.

💡

If you take apart the scooter in winter, bring it to a warm room in advance. 1-2 Cold metal is more fragile, and plastic can crack when dismantled.

How to remove the wheel: front and back

Wheels are the most frequently removed part of the scooter, and they are disassembled to replace the camera or tire, to clean the bearings or repair the brake system, and the process for the front and rear wheels is different because of the location of the engine and the brake.

Removal of the front wheel

1. Turn the scooter upside down (put on the steering wheel and bandage).
2. Unscrew the axle bolt with a hexagon 5 mm (on some models - 6 mm). Do not lose washers and nuts!
3. Remove the wheel from the fork, pulling it gently on yourself. If it doesn't lend itself, knock a little on the axis with a rubber hammer.
4. To replace the camera or tire, blow the wheel away, undermining the tire with a plastic mounting tool (not a screwdriver!).

Removal of the rear wheel (with engine)

The rear wheel is more complex, connected to the motor and the brake disc.

1. Turn off the power (take out the battery).
2. Disconnect the motor connector from the controller (usually located under the band).
3. Unscrew the brake disc mount bolts (torx) T25).
4. Unscrew the wheel axis with a hexagon 5 mm (hold the wheel so it does not fall!).
5. Carefully remove the wheel with the engine. To replace the camera, you will have to separate the engine from the wheel (you will need a torx). T20 screw-holder).

When you reverse assemble the rear wheel, make sure that the motor wires are not twisted or clamped. Incorrect positioning of the wires can lead to a break when driving.

Disassembly of the steering column and folding mechanism

The steering column is one of the most loaded parts of the scooter, and you might need to disassemble it to:

• 🔧 Bearing replacements (if backlash or creaking when turning the steering wheel).
• 🔧 Lubrication or shock absorber replacements (in models with depreciation).
• 🔧 Repair of the folding mechanism (if the steering wheel is not fixed).

Disassembly process:

1. Fold the scooter and fix the steering wheel in the folded position.
2. Unscrew two bolts on the folding mechanism (hexagon 4 mm).
3. Remove plastic covers from the steering column, putting them under the screwdriver (caution – they are fragile!).
4. Unscrew the top nut of the column (a hexagon 5 mm or a special key for bearings).
5. Carefully remove the steering wheel along with the fork. Bearings will remain on the frame or on the fork - they need to be cleaned and lubricated.

For bearing replacement:

• Use the removable or gently knock them out through the mandrel (do not damage the seat!).
• Press the new bearings evenly, without distortion.
• After assembly, adjust the back of the steering wheel - it should rotate smoothly, without jamming.

⚠️ Attention: If the steering wheel walks or folds spontaneously after assembly, then the bearings are installed incorrectly or the nut of the column is not sufficiently tightened!

Dismantling of battery and electronics

The battery is the most expensive part of the scooter, and disassembling it requires special care.

• 🔋 Replacement of the battery (if the capacity has fallen below 60% of the nominal capacity).
• 🔧 Repair of the controller or BMS-charge (for charging errors).
• 🧹 Cleaning contacts (if the scooter does not turn on or glitch).

Instructions for removing the battery:

1. Turn off the scooter and disconnect the charger.
2. Turn over the scooter and unscrew the 4 screws on the bottom cover (torx) T20 for Pro 2, hexagon 3 mm for M365).
3. Carefully remove the lid, pulling it with a screwdriver with a flat sting (start with the back where the latches are located).
4. Disconnect the battery connector from the controller (it is usually black with an orange latch).
5. Unscrew the battery mount screws (there can be from 4 to 6, depending on the model).
6. Take the battery out carefully, don't pull the wires!

When working with electronics:

• 🛠️ Do not touch the battery contacts with metal objects – this can cause a short circuit.
• 🔍 Check the wires for damage. If the insulation cracks, wrap it in tape or shrink it.
• 🧹 Clean the contacts of connectors with alcohol - oxidation often causes unstable work.

Attention. BMS-If the scooter is not charging or discharges quickly, the problem may be the Battery Management System, which requires soldering and multimeter skills, and without experience, it is better to contact the service.

1. Correct connection of connectors (especially the battery and motor).

2. Reliability of contacts - sometimes they do not fully click.

Bearing cleaning and lubrication

Bearings in Xiaomi scooters become contaminated over time, leading to creaking, backlashing or jamming of the wheels. 1000-1500 mile-long.

The work will require:

• 🧴 Means for cleaning bearings (e.g, WD-40 Specialist or kerosene).
• 🧼 A hard bristle brush.
• 🛢️ Lubricant for bearings (e.g. Liqui Moly) LM 50 or analogues).
• 🔧 Bearings Removal (optional).

Step-by-step:

1. Remove the wheel (see section above).
2. Remove the bearings with a removable or gently knock them out through the mandrel (don’t hit the bearing directly!).
3. Wash the bearings in a solvent, then dry with compressed air.
4. Apply lubrication to the inner edge of the bearing (do not overdo it – the excess will lead to heating!).
5. Install the bearings back, pressing them evenly.

Bearings are usually used for the front wheel. 608ZZ (internal diameter 8 mm), for the rear — 6902ZZ (internal diameter of 15 mm. Specify the size for your model!

⚠️ Note: Do not use bearings for lubrication WD-40 Or other penetrating oils -- they wash out the factory lubricant and don't provide long-term protection!

Common Mistakes in Disassembly and How to Avoid Them

Even experienced craftsmen sometimes make mistakes that lead to breakdowns or injuries.

• 🔧 Loss of screws or washers – always fold parts into separate containers with inscriptions.
• 🔌 Wire damage - do not pull the wires during dismantling, disconnect the connectors gently.
• 🔋 Short circuit – do not touch the battery contacts with metal tools.
• 🛠️ Bolt pulling – use a dynamometer key or tighten “from the hand” without undue effort.
• 🔄 Incorrect assembly – photograph each stage of disassembly, especially the location of the wires.

A few more nuances:

• 🚫 Do not disassemble the scooter on the street or in a dusty room - dirt will get into bearings and electronics.
• 🚫 Do not use percussion tools (hammer, chisel) - this deforms the frame and fasteners.
• 🚫 Do not wash the scooter under pressure - water will get into the bearings and battery.

If after assembly the scooter behaves strangely (for example, twitches when accelerating or brakes spontaneously), check:

• Correct connection of the motor connector (the confused polarity will cause reverse rotation).
• The condition of the brake cable - it could chew or break.
• Tightening of the wheel axis - if it is not stretched, the wheel will be "eight".

1. Connection of the battery connectors and the controller.

2. the integrity of the wires (especially near the folding places).

3. Settings in the mobile application (sometimes you need to reset errors).-->
