How to change the wheel on the scooter Xiaomi: disassembly, installation and configuration

Replacing the wheel on the electric scooter Xiaomi — a task that sooner or later faces every owner. wear of rubber, punctures of the camera or damage to the rim require surgical intervention, but not always there is an opportunity to contact the service center. Fortunately, the design of most models (M365, Pro, 1S, 3, 4) allows you to perform the work yourself, with a minimum set of tools and clear instructions.

In this article, we will look at the process from A to Z: from the preparation of the workplace to the final check. Particular attention will be paid to the typical errors that lead to premature wear of new wheels or suspension breakdowns. You will learn how to avoid axle skewing, pump the tire correctly and calibrate the brake system after replacement. And for those who are planning an upgrade, consider the compatibility of wheels from different models Xiaomi and third-party manufacturers.

Importantly, the front and rear wheel procedures have key differences because of the location of the motor and the brake mechanism, and we'll go into the nuances of each case separately so that you don't waste time searching for information on the forums.

Preparation: tools and spare parts

Before you start disassembling, make sure you have everything you need, and not even having one key can take hours to complete, and here's the minimum set that most models will need:

• 🔧 End keys for 5 mm and 10 mm (for bolts of the axle and brake disc attachment)
• 🔨 Hexagons 2.5 mm and 3 mm (for adjusting the suspension and removing the cover)
• 🔩 Screwdriver cross (for dismantling plastic panels)
• 🛠️ Installation blades or plastic spoons (to remove tires from the rim)
• 🚲 Pump with pressure gauge (for accurate tyre pumping)
• 🧴 Lubricant for bearings (e.g. Liqui Moly) LM47 analogue)

If you are planning a complete replacement of the wheel in the assembly (rim). + tire + The camera, you need to purchase an original part for your model. For partial repairs (for example, only tires or cameras) you will need to buy a new part for your model:

• 🛞 New tire (size indicated on the sidewall of an old tyre, e.g. 8.5" for M365)
• 🔄 Camera with a Schrader valve (standard for Xiaomi)
• 🧲 Range tape (protects the camera from punctures with spokes)

Pay attention to the compatibility of parts. For example, the wheels from Xiaomi. M365 suitable for Pro and 1S, But not compatible with the Mi Electric Scooter 3 because of the changed axle diameter. The 4 and 4 Pro require wheels with a 10-inch rim.

⚠️ Warning: Do not use metal mounts to remove the tire - they damage the rim.Plastic blades or special mounts for bicycles (Park Tool). TL-1.2) minimize the risk.

Removing the old wheel: a step-by-step process

Start with safety: turn off the scooter from charging and make sure the battery is at least 50% drained, which will prevent the motor from accidentally turning on when running with the rear wheel.

1. Blow the tire completely by pressing the camera's nipple, making it easier to remove the tires from the rim.
2. Remove the plastic covers from the wheel axis with a screwdriver. Be careful - the latches are fragile!
3. Unscrew the mount bolts: For front wheel: two bolts per 10 mm on each side of the axle. For rear wheel: additionally unscrew the brake disc bolts (end key by 5 mm).

Remove the axle

Now the wheel is separated from the frame, to get to the camera or the tire.

1. Remove the tire from the rim, starting from the side opposite the nipple. Use the mounting blades, putting the edge of the tire on and gradually turning it outward.
2. Take out the camera and inspect it for punctures, mark the site of the chalk damage if you plan to repair it.
3. Check the rim tape, it should completely cover the spokes. Replace it when you wear it.

If you notice the backlash in the axle bearings, they're also worth replacing.

1. Remove the locking rings with the help of circlackers.
2. Remove bearings (you may need a removable or a building hairdryer).
3. Install new bearings 608ZZ (For most Xiaomi models, press them to the limit.

⚠️ Note: Replacement of Mi Electric Scooter rear wheel bearings 3/4 Use only closed bearings (with metal anthers) and open versions quickly fail due to dirt.

Installation of a new wheel: nuances for the front and rear axles

The assembly process mirrors the disassembly, but there are critical moments that determine the durability and safety of the ride.

1. Put the new camera on the rim, slightly pumping it (up to 0.3-0.5 bar) for ease of installation.
2. Set the tyre on the side opposite the nipple. The last section (about 10 cm) is planted with force - use mounting blades.
3. Check the position of the camera: it should not twist or clamp between the tire and the rim.
4. Put the axle in the fork and lock with bolts. Tighten the cross to avoid skewing.

For the rear wheel, steps will be added:

1. Place the brake disc on the axle, combining the holes. Tighten the bolts with a force of 5-6 N·m (do not pull!).
2. Connect the brake cable to the lever on the fork, make sure it doesn't overflex or rub against the tire.
3. Check the gap between the brake pads and the disc - it should be 0.3-0.5 mm. If necessary, adjust the eccentric on the caliper.

After pumping, perform a test run on a flat surface:

1. Check if the wheel is breaking when rotating (a sign of the assembly curve).
2. Make sure the brake is running smoothly, without creaking.
3. Test the scooter at a speed of 10-15 km / h: it should not "lead" to the side.

(1) Tightening of axle bolts (underweight leads to vibrations).

Coaxiality of brake disc (distortion brakes the wheel).

(3) Tyre pressure (low pressure increases rolling resistance).-->

Common Mistakes and How to Avoid Them

Even experienced scooter owners make mistakes when replacing wheels. TOP-5 Problems that users face in forums:

1. The reason for this is the use of metal mounts or excessive effort in installing the tire. Solution: use plastic blades and lubricate the edge of the tire with soap solution.
2. The reason for the new tire's rapid wear is the wrong pressure (too high or low) or the wheel imbalance. Solution: check the pressure with a pressure gauge every week and balance the wheel with loads (like on a bicycle).
3. The reason for the noise of the bearings after replacement is: dirt during installation or insufficient lubrication. Solution: wash the bearings with gasoline before installation and use heat-resistant lubrication.
4. The scooter takes you away, the reason: the wheel angles are not matched (fall-down). Solution: loosen the fork bolts and adjust the symmetry.
5. The brake disc is rubbing against the pads The reason: the disk installation curve or the deformation when the bolts are tightened. Solution: loosen the bolts, align the disc in the center of the caliper and tighten the cross.

Pay special attention to the rear wheel with the engine.

• 🔌 Don’t pull the motor wires – they are fragile and can break away from the controller.
• 🔋 Do not drop the wheel on the floor – the impact can displace the magnets inside the motor, which will lead to a loss of power.
• 🔧 Do not use percussion tools (for example, a hickover) - this deforms the axis.

Wheel upgrades: what can be improved?

Replacing the wheel is a great reason to upgrade. Here are 3 popular modifications that will improve the performance of the scooter:

• 🚀 Tight tyres (e.g. tubeless tyres, CSL Solid Tire: No punctures, long lifespan. Cons: hard driving, worse grip on wet roads.
• 🏔️ Tread tires (e.g. Kenda) K526) Pros: better passability on gravel and grass. Cons: wear out faster on asphalt, higher rolling resistance.
• ⚡ Lightweight rims (e.g. Carbon Fiber from Minimotors) Pros: 0.3-0.5 kg weight reduction, better coast down. Cons: high price, fragility when hit.

When choosing non-original wheels, consider:

• Rim diameter: must match the original (8.5" or 10").
• Tire width: Too wide a tire can rub against a fork.
• Brake Disk mount type: Some models (such as the Xiaomi 4 Pro) use a 6-bolt mount instead of the standard central one.

For models with pneumatic tyres (M365, Pro 2) A popular upgrade is to install gel or foam inserts instead of the camera. This eliminates the risk of punctures, but makes the ride harder. The best option for urban conditions is Tannus Armour (combines cushioning and puncture protection).

After-replacement maintenance: how to extend the life of a new wheel

To make the new wheel last longer, follow these guidelines:

1. Check the pressure every 2 weeks. pneumatic tires lose 0.1-0.2 bar per month even without puncture.
2. Wash the wheel after riding on mud. Abrasive particles accelerate wear on the tires and bearings.
3. Avoid heavy braking at high speed – this deforms the rim.
4. Keep the scooter in a dry place. Humidity corrodes the spokes and axle.
5. Check the backlash of the wheels every 500 km. When there are beatings, pull the axle bolts.

For winter use:

• 🌨️ Reduce tire pressure by 0.3–0.5 bar for better grip.
• ❄️ Install studded tires (for example, Innova Winter).
• 🔋 Avoid driving on ice – a sharp braking can derail the brake disc.

If you notice uneven wear on the tire (one side wears off faster), this is a sign:

• Incorrect pressure (too low or high).
• Wheel axis skewed.
• Bearing wear.

💡

Regularly inspect the brake pads. When worn up to 1.5 mm, they begin to scratch the brake disc, which leads to deformation and expensive repairs.
