Introduction: Why it is important to be able to

The rear wheel on Xiaomi’s electric scooter is not just a design element, but a knot that integrates the engine, braking system and transmission. Over time, it requires maintenance: replacing the tire, repairing the engine or cleaning the brake pads. However, improper dismantling can lead to damage to the wiring, thread failure or even failure of the controller.

In this article, we will analyze the process of removing the rear wheel on popular models – Xiaomi M365, Pro 2, 1S, Essential and Pro. The key differences between versions, tools and common mistakes that even experienced owners make, if you plan to repair yourself, this guide will help you avoid costly breakdowns.

We warn you right away that if your scooter is warranted, disassembling the wheel will cancel it, in which case you should contact the service center, for everyone else, we will start preparing.

What tools will you need

Without the right tool, it’s almost impossible to remove a wheel on Xiaomi.

• 🔧 End key 14 mm (or head with a collar) - to unscrew the wheel axis.
• 🔧 Hexagon by 5 mm - for fixing the brake disc (on models with disc brake).
• 🔧 Flat screwdriver - for slashing the engine cover and connectors.
• 🔧 Cross screwdriver - for some models (for example, Pro 2).
• 🔧 Flat-slippers or circ-cutters - to work with spring stoppers.
• 🔧 Hammer (not heavy) - may be useful for neat knocking out the axis.
• 🔧 WD-40 Or similar lubrication – if the thread is boiled.
• 🔧 Multimeter – to check the integrity of the wiring after dismantling.

For Xiaomi models M365 and 1S It's enough of a 14 mm key and a hexagon. But Pro 2 and Essential might need a special bearing detacher if you're planning to replace them. And prepare a clean cloth and a plastic container for small parts, cogs tend to get lost.

⚠️ Warning: Do not use a gas key instead of the end key! it can tear the edges on the axis nut, which will complicate further assembly.

If you don't have experience with the technology, we recommend that you first watch the video disassembly for your model, which will help visualize the process. For example, on YouTube there are detailed videos on the dismantling of Xiaomi. M365 nuanced.

Preparation of the scooter for disassembly

Before you start dismantling, the scooter needs to be properly prepared, which will save you from damage and simplify the process.

1. Turn off the scooter and remove the battery (if possible). On models with a non-removable battery (Pro 2, Essential), it is enough to hold the power button for 10 seconds to completely shut down.
2. Turn the scooter over so it's on the steering wheel and the footrest, and put a soft cloth under the gas handle so it doesn't scratch the body.
3. Clean the wheel and axle of dirt and dust, which is especially important if you drive on wet roads - moisture could get into bearings.
4. Take a picture of the location of the wires and connectors, and that'll help you connect everything back together.

If you remove the tire replacement wheel, blow the air out of the chamber to the end. This will make it easier to dismantle. For models with tubeless tires (for example, Xiaomi Pro 2 with a tire 8.5), you may need a special tool for disassembly.

⚠️ Attention: On scooters Xiaomi with a system KERS (regenerative braking) when disassembling the wheel, be sure to disconnect the motor connector from the controller. Otherwise, when accidentally pressing the brake, a short circuit may occur!

If you are planning to replace bearings or repair the engine, pre-order the necessary parts. M365 bearings are fine 6004-2RS, a for Pro 2 — 6902-2RS. Check compatibility with the seller.

Step-by-step: Removal of the rear wheel

Now, the manual is suitable for most Xiaomi models, but we will specify the nuances for specific versions.

Step 1: Unscrew the axis nuts

On both sides of the wheel, you'll see the 14mm nuts. They can be tightened very tightly, so:

1. Fix the scooter so that it does not spin (you can pinch the front wheel between the legs).
2. Put the end key on the nut and try to spin counterclockwise. If it doesn't, splash it. WD-40 and wait 5-10 minutes.
3. Unscrew the nut on one side by 2 or 3 turns, then move to the other side, which will prevent axis skewing.

On the Pro 2 and Essential, there may be a locking puck under the nut, and carefully put a screwdriver in it and remove it.

Step 2: Remove the brake disc (if any)

Disc brake scooters (M365, 1S, Pro) after removing the nut you will see a brake disc, fixed by two screws under the hexagon by 5 mm:

1. Unscrew the screws and remove the disc. Be careful, it can be sharp!
2. If the disc is stiff, don't hit it with a hammer. WD-40 wait.

On models with electronic brakes (for example, Pro 2) there is no disk - instead of it, a Hall sensor is used, which is attached to the axle.

Step 3: Remove the axle and wheel

After removing the nuts and brake disc, carefully remove the axle from the frame.

• Try to tap it lightly with a hammer through a soft pad (for example, a wooden bar).
• Check if the wiring is interfering with the motor, and it may need to be disconnected.

Xiaomi. M365 and 1S The axis comes out relatively easily, but on the Pro 2, you might need a detacher because the bearings sit tighter.

Step 4: Disconnect the motor wiring

This is the most critical moment! The motor wires are connected to the controller through a connector that is under the plastic cover on the frame.

1. Put the lid on a flat screwdriver and remove it.
2. Disconnect the connector (usually white or black) and do not pull the wires, just the case of the connector!
3. If the connector is boiling, don't force it. It's better to drip alcohol or contact lubricant.

On models with a system KERS The motor connector can be energized even when the scooter is off! Before disconnecting, be sure to check with the multimeter.

Step 5: Remove the wheel from the axle

Now the wheel should slip off the axle easily.

• Check if the brake pads interfere (on models with mechanical brake).
• If the wheel is sitting tight, it may have deformed the axle, in which case it will need to be replaced.

After removing the wheel, check the bearings and gear of the motor. If you have a backlash or a creak, they should be replaced too.

Features for different Xiaomi models

Although the principle of removing the wheel is similar, each model has its own nuances. Let's take a closer look at them.

For Xiaomi Pro 2 and Essential, it is important to remember the system. KERS. When you unplug the wheel, don't press the brake lever, it can cause a voltage surge in the controller. Also, these models often have problems with the oxidation of contacts in the motor connector. If the scooter twitches when driving, first of all check this connector.

Nana M365 and 1S A common problem is the wear of the motor gear, and if you hear a grinding sound when you accelerate, you probably need to replace it. XMSXJ-Q03).

💡

If you remove the tire replacement wheel, apply a little silicone lubricant to the axle before assembly, which will make the next dismantling easier and protect against corrosion.

Common Mistakes and How to Avoid Them

Even experienced Xiaomi scooter owners sometimes make mistakes when removing the rear wheel, and here are the most common ones and ways to prevent them:

• 🔧 The reason is because you use the wrong key or you use too much force. Always use the 14mm end key and don't force it if the nut doesn't work. WD-40.
• 🔌 Motor connector damage. Many people pull wires instead of the connector body, which causes the contacts to break. Always take the plastic case!
• 🛠️ Loss of locking washers or screws. Small parts are easily lost. Use a magnetic pallet or a container with a lid.
• 🔋 Forget to turn off the battery. KERS This can lead to a short circuit. Always turn off the scooter and disconnect the battery (if it is removable).
• 🚲 Wrong assembly. For example, forgetting to put a locking washer or pulling nuts, which leads to a backlash of the wheel or difficulty spinning.

Another common problem is that you're damaging the brake disc, and if you take it off with a hammer, it can bend, and the brakes will creak or not work properly, and you'd better use a special camera or you could gently screw the disc.

If the scooter does not go after assembly or gives an error, check:

1. Correct connection of the motor connector.
2. Integrity of wiring (whether there are breaks or closures).
3. The axis nuts are tightened evenly.

💡

If the wheel is having trouble rotating after assembly, chances are you've pulled the axle nuts or installed the bearings incorrectly.

When is the best time to contact the service

Despite the fact that you can remove the rear wheel on Xiaomi yourself, there are situations when it is better to trust the professionals:

• 🔧 If you've never done a repair job and you're not confident in your abilities, it can cost more to make a mistake than a service.
• 🔌 If you find melted wires or burnt-out elements on the controller during the disassembly, that's a sign of a serious malfunction.
• 🛠️ If you need to change the bearings or the gear of the motor, but you don't have a removable, you can damage the axle without it.
• 📱 If after assembly the scooter makes an error E014, E015 Or other codes associated with the motor, which could indicate a problem with the controller.
• 🔋 If the scooter is guaranteed, any interference will cancel it.

The cost of removing and installing the rear wheel in the service is usually 500-1500 rubles, depending on the model and the complexity of the work. If you need to replace bearings or repair the engine, the price can rise to 3000-5000 rubles. However, it is still cheaper than buying a new wheel assembled (from 8000 rubles).

If you decide to repair the scooter yourself, but faced difficulties, do not hesitate to seek advice on thematic forums, for example, 4PDA Xiaomi Community, where they often post detailed photo reports on repairs.
