Removing the wheel on the Xiaomi scooter: when it is necessary and what you need to know
Xiaomi electric scooters are a popular transport for city trips, but even the most reliable models (M365, Pro 2, 1S, Essential) requires periodic maintenance. One of the most common procedures is to remove the wheel - whether it is to replace the tire, repair the camera, clean the bearings or eliminate a puncture. However, improper dismantling can lead to rim damage, wire rupture (at the rear wheel with the motor), or even failure of the controller.
In this article, we will discuss the step-by-step algorithm for removing both the front and rear wheels on Xiaomi scooters, specify the necessary tools and warn against typical errors. We will pay special attention to the nuances of working with models equipped with disc brakes (Pro 2, 3 Lite) and a motor-wheel. If you have never repaired equipment, do not worry: with the right approach, the procedure will take no more than 30-40 minutes.
Before you start, make sure that the problem does require the removal of the wheel. For example, a puncture of the rear wheel camera on a motor-wheel scooter can be eliminated without completely dismantling, using a special sealant through the nipple, which will save time and reduce the risk of damage to the wiring.
What tools will you need
You'll need a minimal set of tools to work, but not having one can make the task impossible.
- ๐ง Hexagonal keys (dimensions 4 mm, 5 mm and 6 mm) - for unscrewing the wheel mounting bolts and brake disc.
- ๐จ End keys or heads (13 mm, 15 mm) - for the nut of the rear wheel axis (on models with a motor).
- ๐ง Carrot key (10 mm or 13 mm) - as an alternative to the end key.
- ๐ ๏ธ Flat and cross screwdrivers - for removing plastic covers and smearing of fixers.
- ๐งฒ Magnet or tweezers โ so as not to lose small washers and bearings.
- ๐ฅ WD-40 or similar lubrication - if the bolts are acidified (relevant for scooters operated in the rain).
- ๐ฆ Plastic screeds - for fixing wires when removing the rear wheel.
For models with disc brakes (Xiaomi Pro 2, 3 Lite) additionally require:
- ๐ง Key for brake discs (usually) T25 or T30).
- ๐งด Degreasing agent (alcohol or acetone) - to clean the rotor and pads.
If you are planning to replace bearings, prepare a removable (you can use improvised means, for example, old keys) and new bearings size. 608ZZ (for the front wheel) or 6902RS (rear-engine).
โ ๏ธ Attention: Do not use a hammer to knock out the wheel axis - this deforms the bearings and can damage the rim. If the wheel is not removed, check if all bolts are unscrewed, and treat the thread with lubrication.
Preparation of the scooter for the dismantling of the wheel
Before removing the wheel, the scooter must be properly prepared:
- Turn off the power โ press and hold the 5-second switch until the indicator goes out. This will prevent the motor from accidentally turning on when working with the wiring.
- Remove the battery (if the model allows). M365 and 1S Removable battery - press the lock at the bottom of the platform and pull up. On the Pro 2 and 3 Lite, the battery is built-in, so just turn off the motor connector (more on this below).
- Turn the scooter over so it's on the steering wheel and the footrest, and put a soft cloth under the handle of the gas so that you don't scratch the plastic.
- Clean the wheel and axle of dirt โ this will simplify access to bolts and prevent debris from getting into bearings.
If you're working with the rear wheel, be sure to unplug the motor connector. It's under a plastic lid on the axle and it's locked by a latch. Carefully pull the jack to the sides without pulling the wires. On Xiaomi Pro 2 and newer models, the jack can be secured with a screw -- remember to unscrew it.
Power's off.

Step-by-step: how to remove the front wheel
The front wheel on Xiaomi scooters is easier to remove than the rear, since it has no motor and wiring, but there are some nuances here, especially if the model has disc brakes.
Step 1: Removal of the plastic cover and brake disc
1. Put a flat screwdriver on the plastic cover on the wheel axis (it is fixed by the latches). Be careful - the plastic is fragile.
2. If the disc brake (Pro 2, 3 Lite) is installed on the scooter, unscrew the two screws of the brake caliper attachment (usually T25). Remove the caliper and hang it on a wire or screed without disconnecting the hydraulic hose.
3. Unscrew the brake disc mount bolts to the hub (usually 4 mm or 5 mm hexagon). Remove the disc and put it aside.
Step 2: Untwisting the wheel axis
1. On both sides of the axle, find nuts or bolts (depending on the model). M365 and 1S This is a turnkey nut 13 mm, on Pro 2 - bolts under a hexagon 6 mm.
2. Holding the axle on one side with the key, unscrew the nut/bolt on the other. If the thread is acid, treat it. WD-40 and wait 5-10 minutes.
3. Carefully remove washers and locking rings (if any). Remember their order - when assembled, they must fall into place.
Step 3: Removing the wheel
1. Pull the wheel on yourself, holding the fork with the other hand. If it does not come down, sway it slightly from side to side.
2. After removing the wheel, check the condition of the bearings. If they are squeaking or squeaking, they need to be replaced.
3.Inspect the rim for cracks or deformities. Xiaomi scooters often wear out the inside of the rim due to friction against the brake pads.

If the wheel is not easily removed, do not apply excessive force - check if all bolts are unscrewed. Sometimes you forget to remove the locking ring or brake disc.
How to remove the rear wheel with the engine
Xiaomi's scooters have a built-in motor, so it requires more care to dismantle it. The main difficulty is wiring, which is easily damaged if handled carelessly. M365, Pro 2, 1S Essential.
Step 1: Turn off the motor and remove the cover
1. Unscrew two screws on the plastic axle cover (usually T20 Take the lid off, or the cross screwdriver.
2. Under the lid, you'll see a motor connector (white or black plastic connector) gently disconnect it by pulling the locks on the sides. Don't pull the wires!
3. If the disc brake is installed on the scooter, unscrew the caliper (as in the case of the front wheel) and remove the brake disc.
Step 2: Untwisting the axis
1. The rear axle is fixed with one central nut (usually 15 mm) and two bolts on the sides (a hexagon 5 mm or 6 mm).
2 Holding the axis with the key, unscrew the central nut. Be prepared - the axis may turn, so lock it with the second hand.
3. Remove the washers and the locking ring (if any). On some models, a spring-loaded puck is hiding under the nut - don't lose it.
Step 3: Removal of the motor wheel
1. Gently pull the wheel over you while holding the frame. If it doesn't come off, spin it slightly from side to side.
2 After removing the wheel, inspect the motor wires, they should be free to exit the axle. If the wires are tight, check if they are clamped in the frame.
3. Check the condition of the motor-wheel bearings. On Xiaomi, they often fail due to moisture. Luft or rotating noise is a sign of needing replacement.
โ ๏ธ Attention: On Xiaomi Pro 2 and 3 Lite models, a Hall sensor is installed in the rear wheel axis to monitor speed. When assembled, make sure its wires are not twisted or clamped. ERROR 21 on display.
Frequent Mistakes and How to Avoid Them
Even experienced Xiaomi scooter owners sometimes make mistakes when removing wheels, and here are the most common ones and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Unscrewing of bolts with the scooter on | Short circuit, failure of the controller | Always turn off the power and disconnect the battery. |
| Loss of washers or locking rings | Luft wheels, accelerated wear of bearings | Stack the parts in order of removal (use a magnet) |
| Application of force on the jammed axle | Bearing or rim deformation | Handle the thread WD-40 And wait 10-15 minutes. |
| Motor wire twisting | Wiring break, error ERROR 21 | Fix the wires with screeds and do not pull them. |
| Ignoring bearing inspection | Increased noise, vibrations, rapid wear of the wheel | Always check the back and back of the spin. |
Another common problem is axle thread damage, which occurs when you use excessive force when you twist the nuts, use a dynamometer key (if you have one), and twist the nuts at a maximum of 40 to 50 Nm.
On disc brake models (Pro 2, 3 Lite), it is often forgotten to clean the caliper after the wheel is removed, which leads to uneven wear of the pads and reduced braking efficiency. Always clean the brakes of dirt and lubricate the guide calipers.
What if the wheel is not removed even after all the bolts are unscrewed?
Replacing a tire or camera: a brief guide
If you removed the wheel for puncture repair or rubber replacement, here is a brief guide to further actions:
- Lower the air from the chamber by pressing the nipple.
- Put the tire on one side of the rim, use plastic mounts (not screwdrivers!) to keep the camera from being damaged.
- Take out the camera and check it for punctures, mark the puncture site with chalk.
- Replace the camera or seal the puncture with a rubber patch and glue (such as Tip Top or Red Sun).
- Check the tire from the inside - often the cause of punctures are sticking spokes or sharp rim edges.
- Set the camera back, slightly pump it (to take shape) and tuck the tire on the rim.
- Pump the wheel to the recommended pressure (35โ50) PSI model-wise).
For scooters Xiaomi suitable tire size 8.5" (for M365, 1S) Or 10" (for Pro 2, 3 Lite).When choosing tires, pay attention to the tread:
- ๐๏ธ Slick (smooth) - for asphalt, low rolling resistance.
- ๐ณ Half-way is a universal option for the city and parks.
- ๐๏ธ Winter (with spikes) - for snow and ice (requires caution on the asphalt).
๐ก
When changing the camera, always check the rim for burrs or rust, and even a small scratch can cause a repeated puncture.
Wheel assembly and test inspection
After repairing or replacing parts, the wheel needs to be properly assembled and checked.
- Install bearings (if you've taken them off) and they should sit tightly, without backlash. Use a pipe of the right diameter or a detachable to press them.
- Put the wheel on the axle, combining bolt holes. Make sure that the motor wires (for the rear wheel) are not twisted.
- Twirl the bolts/nuts in reverse order. Don't forget the washers and the locking rings!
- Connect the motor connector (for the rear wheel) and install the battery.
- Check the brakes. For disc brakes, make sure the rotor doesn't rub against the pads. Adjust the caliper if necessary.
- Ride on a scooter at low speed, checking for no vibrations and extraneous noises.
After assembly, be sure to check:
- ๐ The smoothness of the wheel rotation - it should spin without jamming.
- ๐ Brakes โ they should work smoothly, without creaking.
- โก No errors on the display (for example, ERROR 21 indicates a problem with the motor).
โ ๏ธ Warning: If the scooter twitches when accelerating or jerks after assembly, check the phasing of the engine. You may have misconnected the connector. On Xiaomi models M365 and Pro 2 motor connector has a key (protrusion) that prevents improper connection, but some clones may not have it.
