The rear wheel of Xiaomi's electric scooter is one of the most laden parts. It wears out, breaks through or gets damaged over time when you're driving on rough roads. If you notice that the scooter starts waving, the back lift comes in, or the wheel stops spinning smoothly, it's time to replace it. In this article, we will analyze step-by-step instructions for models. M365, Pro, Pro 2, 1S, Essential and others, and how to avoid common mistakes.

Many owners are afraid to disassemble the scooter themselves for fear of damaging the electronics or the motor. In fact, the process of replacing the rear wheel is easier than it seems, the main thing is to follow the algorithm and use the right tools. We will describe in detail each step from removing the old wheel to installing a new one, including the nuances of connecting wires and adjusting, and also give advice on how to extend the life of the new wheel and which parts are better to choose.

If your Xiaomi scooter starts making extraneous sounds when driving, it is difficult to hit the steering wheel or the wheel is scrolling with difficulty - do not rush to bring it to the service. In 80% of cases, the problem is solved by replacing the rear wheel, and you can do it yourself in 30-60 minutes. Even if you have never repaired the equipment, our recommendations will help you cope without mistakes.

What tools will be needed to replace

Before you start, prepare everything you need, and without the right tools, you risk breaking the thread, damaging the case, or damaging the wiring, and here's the minimum set you'll need:

• 🔧 End key 14 mm (or head with a collar) - to unscrew the wheel axis.
• 🔧 Hexagon by 4 mm - for removing the cover of the motor wheel (on some models).
• 🔧 Screwdriver cross (PH2) — stripping.
• 🔧 Flat-bottoms or passages - will help keep nuts when unscrewed.
• 🔧 Knife or plastic spatula - for careful removal of plugs.
• 🔧 Dynamometer key (optional) - for precise nut tightening (recommended moment - 40-50 N·m).
• 🧴 Lubrication for bearings (e.g. Liqui Moly or WD-40 Specialist – if you plan to maintain old bearings.
• 🧤 Gloves – protection of hands from dirt and sharp edges.

Also prepare a new wheel - it should be compatible with your scooter model.For Xiaomi M365/Pro/1S Wheels with markings are fine. 8.5" (216 mm) and width 2.125". Pay attention to the type of tire: pneumatic (inflatable) or cast (without a camera), the latter are less prone to punctures, but less cushioned.

If you plan to replace not only the wheel, but also bearings, buy a kit with a marking. 6004-2RS (oxide 20 Don't skimp on quality, cheap bearings will fail quickly.

Scooter Preparation: How to safely remove the wheel

Before disassembling, be sure to follow these steps to avoid damage and injury:

1. Turn off the scooter - press the power button for 3 seconds until the indicator goes out.
2. Unplug the battery (optional, but recommended) to do this, unscrew the 4 screws on the bottom panel (under your feet) and gently disconnect the battery connector, which will protect the electronics from short circuit.
3. Turn the scooter upside down with your wheels. Place it on a soft surface (like a mat) so you don't scratch the steering wheel or the display.
4. Clean the wheel and axle of dirt – this will make it easier to unscrew the nuts and prevent sand from entering the bearings.

Now you can start dismantling. Start by removing the plastic motor-wheel cover (if you have one). M365/Pro It's mounted on the latches -- put it in a knife or a plastic spatula. 2/1S the cover can be fixed by a screw under the hexagon.

Attention! Don't pull the lid with force, because the wires run from the motor to the controller, carefully unplug the connector (usually white or black) and put the lid aside.

Step-by-step: how to remove the old wheel

The most important step is to dismantle the old wheel, so it's important not to damage the axle thread or confuse the assembly order.

1. Unscrew the counternut (if any) - it is on the left side of the axle (brake side). Use the end key on 14 mm. Hold the axle on the other side with pliers so that it does not scroll.
2. Remove the locking ring (on some models) and it fixes the bearing, and put it in a screwdriver or a special detachment.
3. Unscrew the main nut on the right side of the axle. It can be tightened strongly - if necessary, use a lever (for example, a pipe to the key).
4. Take the wheel off the axle. Pull it on yourself while you scroll it, and if it's sour, knock on the axis with a hammer through a wooden shelf.
5. Disconnect the motor wires (if you have an electric motor), the connector is usually inside the axle. Remember or take a picture of the connection order!

At this stage, you may face two problems:

1. Rusty or boiling axis - treat it with penetrating lubricant (WD-40) And wait 10-15 minutes.
2. Damaged wires – if the insulation is rubbed, replace them or insulate them with a shrink tube.

Critical! On Xiaomi Pro 2 and newer models, the motor wires run inside the axle and are fixed with screeds. Don't pull them, release the mounts first.

How to install a new wheel: nuances and mistakes

Installing a new wheel is a reverse-removal process, but with a few key points:

1. Check the bearings. If you bought a wheel without them, move the old ones (pre-cleaned and lubricated) or install new ones. Bearings should sit tight, without backlash.
2. Connect the motor wires (for electric wheels) and connect the connectors in the same order as they were previously connected. M365 It's usually black and white wires.
3. Put the wheel on the axle. Make sure it sits flat, and the distortions will cause the wheel to beat when driving.
4. Tighten the nuts. First, hand-wrap them, then key them. Don't pull them! The recommended moment is 40 to 50 Nm. Too much puff will damage the bearings.
5. Set a locking ring and counternut (if any).

After assembly, be sure to check:

• 🔄 The wheel rotates freely, without jamming.
• 🚫 No backlash in bearings (swap the wheel to the sides).
• 🔌 The wires are not tightened or clamped.

Typical errors in installation:

• ❌ Mixed motor wires – the scooter will not go or the wheel will spin in the opposite direction.
• ❌ Uneven tightening of nuts - leads to the beat of the wheel.
• ❌ The stain on the axle accelerates the wear of bearings.

💡

Before you first drive after you change the wheel, check it idling: lift the scooter off the ground, turn it on and give it to the gas. Make sure the wheel rotates smoothly, without jerking.

How to choose a quality wheel for Xiaomi: types and brands

The right choice of wheels is not only about driving comfort, but also about safety.

For most urban settings, a half-treaded pneumatic wheel is the best choice, which balances comfort and wear. If you drive on bad roads often, consider reinforced gel-filled wheels (such as the Tannus Armour) — they are not afraid of punctures, but they cost more.

When buying, check:

• 🔍 Compatibility with the model of the scooter (check with the seller or look in the technical documentation).
• 📏 Size – Must match the original (8.5" for most Xiaomis).
• 🔧 Components – some wheels are sold without bearings or nuts.

Tip: If you often drive in the rain, choose a wheel with a deep tread and wet grip marking, which better divert water and reduce the risk of aquaplaning.

Service after replacement: how to extend the life of the wheel

Replacing the wheel is only half the battle, so to make it last longer, follow these guidelines:

• 🔧 Check the pressure in the pneumatic wheel every 2 weeks. The optimal value is 2.5-3.5 bar (indicated on the sidewall of the tire).
• 🛑 Avoid heavy braking – this reduces the life of the tread.
• 🚿 Wash the wheel after riding on mud - sand and salt destroy rubber and bearings.
• 🔄 Periodically check the backlash - if it appears, tighten the nuts or replace the bearings.

If you notice that the wheel is starting to wear out quickly on one side, it's a sign of a misalignment or imbalance.

1. Check to see if the nuts are tight.
2. Make sure the axle is not bent.
3. If the problem remains, contact the service for balancing.

Attention! ⚠️ Do not use aggressive detergents (such as solvents or gasoline) to wash the wheels; they destroy rubber and bearing seals; warm water and soap are enough.

💡

Regular maintenance (pumping, cleaning, backlash check) increases the life of the wheel by 30-50%.

Frequent problems after replacement and how to fix them

Even if you did everything right, you might have problems after you change the wheel.

If the wheel turns the other way after the replacement, you have confused the engine phases. Turn off the wires and swap any two contacts on the connector (usually black and green wires on Xiaomi). M365).

Attention! ⚠️ If the scooter after the wheel replacement does not turn on or gives an error, check:

• Connect the battery (if you have disconnected it).
• Integrity of motor wires (possibly damaged insulation)
• Controller condition (rarely, but it burns when short circuit).
