Replacement of the rear wheel camera on the Xiaomi electric scooter: a detailed guide with a photo

The rear camera on Xiaomi Electric Scooter is one of the most vulnerable parts in active operation. Punctures, cuts or natural wear of rubber lead to the fact that the wheel starts to deflate, and riding becomes uncomfortable or impossible. If you are faced with this problem, do not rush to bring a scooter to the service: you can replace the camera on the rear wheel yourself, saving up to 1500-2000 rubles.

In this article, we’ll break down the whole process from A to Z: from choosing the right camera for your Xiaomi model (including the one that is the best camera for your Xiaomi model). M365, Pro 2, 1S, 3 Lite and others) before turning the wheel apart, installing a new camera and assembly, and we will pay special attention to typical errors that lead to repeated punctures or rim damage. You will also learn how to check the leakproofness after replacement and what tools are really needed, and what you can do without.

Important: the replacement process on the rear wheel is more difficult than on the front wheel, due to the presence of the motor and the brake disc. But with our instructions and photos, even a beginner can cope in 1-1.5 hours. Ready? Then let's go!

What camera to choose for the rear wheel Xiaomi Scooter

The first and most important step is to buy the right camera, and if you make a mistake, you'll either make it impossible to install the rubber or it'll break quickly, and here are the key parameters to look at:

• 🔹 Wheel size: All Xiaomi models (except Mi Electric Scooter) 4) rear wheel has diameter 8.5 The exception is Mi. M365 and Pro with wheels 8.5", and also Mi 3/4 s 10". Refine the size of your model’s characteristics.
• 🔹 Camera type: The original Xiaomi cameras have an autonipple (Schrader), but there are options on the market with a bicycle nipple (Presta!
• 🔹 Camera width: Standard width - 2.125" (54 mm). "Camera width 1.95" or 2.5" may not fit.
• 🔹 Material: Butyl rubber is the best option (longer holds pressure). Cheap synthetic rubber cameras are released in 2-3 days.

Where to buy? Xiaomi's original cameras are sold in branded stores (article: MD-JQJR01FM for M365/Pro), But their price is often overpriced (1200–1500 Analogues from Kenda, Innova or Chaoyang are cheaper (600–900 The sites tested are AliExpress (rated suppliers). 98%+), Bet, Ozon (seek reviews from installation photo).

⚠️ Warning: Don't buy cameras that say "Tubeless" -- they're designed for tubeless wheels and won't work for Xiaomi. + “Tyre” – a separate purchase of a camera will cost less, and the tire rarely wears out at the same time.

Required tools and materials

To replace the camera on the rear wheel Xiaomi you need a minimum set of tools. Do not believe the "gurus", who advise to buy professional tires for 3000 rubles.

• 🔧 Flat mounts (2-3 pieces) - plastic is better, so as not to scratch the rim.
• 🔧 Set of hexagons (mandatory 4 mm and 5 mm for removal of the brake disc).
• 🔧 Nipple key (usually included with pump).
• 🔧 Pump with pressure gauge (to accurately put pressure).
• 🔧 Soap solution (to check leakage).
• 🔧 Wrap and gloves – the wheel will be dirty!

In addition, it may be useful:

• 🛠️ Tyre lubricant (such as Slime or regular shampoo) – makes it easier to install the camera.
• 🛠️ The sleeves of the old one (if the old one is broken).
• 🛠️ Lantern – to inspect the tire for the presence of nails or glass.

⚠️ Warning: Don't use screwdrivers or knives instead of mounts! They'll damage the tire or the camera. If the mounts slide, wrap them in tape for better grip.

💡

Before starting work, take a picture of the location of the brake disc and motor wires - this will help to properly assemble the wheel back.

Scooter preparation: removal of the rear wheel

To get to the camera, you have to dismantle the rear wheel, which is the most time-consuming stage because of the motor and the brake.

1. Turn off the power: Turn off the scooter with a button and disconnect the battery (if the model is collapsible). M365/Pro remove the plug from the controller.
2. Remove the brake disc: Unscrew 2 bolts with a hexagon of 4 mm (on some models - 5 mm). Carefully remove the disk and put aside.
3. Unplug the engine: M365/Pro need to unscrew 4 motor-mounting bolt (hex-sided) 4 mm), then disconnect the power connector. 2/3 Lite motor is removed with the wheel.
4. Remove the wheel from the axle: Unscrew the axle nuts with the key on 10 mm 13 mm for Mi 3/4). Pull out the axle and carefully remove the wheel.

If the wheel is not off, don't knock on it! Put the scooter on its side and gently wove the wheel left and right, at the same time pulling on itself. Often the problem is with sour bearings - they can be lubricated. WD-40.

After removing the wheel, carefully examine:

• 🔍 Tire for nails, glass or cuts (especially from the inside!).
• 🔍 Rim - whether there are dents or rust that can puncture a new chamber.
• 🔍 Bearings: If they are lufting or creaking, replace them with the camera.

Step-by-step replacement of the camera: disassembly and installation

Now, the most important step is to replace the camera, and the rule is, take your time to avoid damaging your new camera or tire.

Check the size of the new camera (should match the old one)|Prepare a soap solution to check the leakiness|Make sure the tire is not damaged from the inside.|Grease the edges of the new chamber with soap solution-->

1.Removing the old camera

1. Lower the wheel: Press the nipple (or unscrew the cap and press the pin) and blow the air completely.
2. Pull the tyre off the rim: Insert the mount between the tyre and the rim, then hook the second mount 10-15 cm from the first. Carefully "roll out" the edge of the tyre behind the rim.
3. Remove the camera: After one edge of the tire is removed, pull the nipple out of the hole in the rim and remove the camera.

Checking the tire and rim

Before installing a new camera, be sure to inspect the tire from the inside - often the cause of repeated punctures are small stones stuck in the rubber or metal shavings. Run your hand over the inner surface of the tire (carefully so as not to hurt!).

• 🔸 Burrs or sharp edges (can be cleaned with sandpaper).
• 🔸 Rust (remove with rust converter).
• 🔸 Damaged single tape (replace if necessary).

Installation of a new chamber

1. Check the camera: Inflate it a little (up to 0.5-1 bar) to make sure there is no marriage.
2. Set the nipple: Pull it into the rim hole and lock it with a nut (don't tighten too much!).
3. Spread the camera: Lay it inside the tire, make sure there are no torsions. The camera should lie flat, without folds.
4. Put on the tire: Start on the side opposite the nipple. Use the mounts to fill the edge of the tire under the rim. The last section (near the nipple) is the hardest, and the lubrication will help.

Tip: if the tire is tightly fitting, heat it with a hair dryer (not higher than 60)°C) - rubber will become more elastic.

Pumping and inspection

Pump the wheel gradually:

1. First, up to 1 bar, then check if the tire is evenly settled.
2. Apply the soap solution to the rim and nipple - if bubbles appear, then there is a leak.
3. Bring the pressure to the recommended (usually 3.5-4.5 bar for Xiaomi).

(1) Density of the nipple to the rim (possibly a rubber pad is needed).

(2) The integrity of the new chamber (sometimes marriage is only manifested under pressure).

(3) Nipple tightness (tighten the nut with the key).-->

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when replacing the camera with Xiaomi Scooter.

• 🚫 Tire damage by installation → Use plastic shoulder blades or wrap metal tape.
• 🚫 Camera twisting → Before installation, slightly inflate the camera so that it takes shape.
• 🚫 Insufficient pressure → The wheel must be inflated to 3.5-4.5 bar (check with a manometer!).
• 🚫 Forgot to check the rim → Metal shavings or rust will puncture a new camera in a day.
• 🚫 Incorrect brake assembly → After installing the wheel, check that the brake disc rotates freely.

Another common mistake is ignoring the wheel balance, and if the scooter vibrates at speeds above 20 km/h after the replacement, the tire or camera is not evenly installed.

1. Lower the wheel.
2. Remove the tire and check if there are any folds on the camera.
3. Reset the tire, starting on the opposite side of the nipple.

⚠️ Attention: If after replacing the camera, the scooter began to accelerate worse or there was an extraneous noise, check if the tire touches the brake disc or frame.

What to do if the camera drops after replacement

Situation: you set up a new camera, you pumped the wheel, and an hour later it went down again, and the reasons may be different, and it's not always the camera's fault.

1. Check the nipple: Unscrew the cap and drop saliva on the nipple - if there are bubbles, the nipple misses. Try to tighten the nut with a key or replace the nipple (costs 50-100 rubles).
2. Look at the rim: Remove the tire and swipe the inside of the rim -- often there are burrs. Check the rim ribbon: if it's shifted, the metal spokes will puncture the camera.
3. Camera test: Inflate the camera separately (without a tire) and lower it into water, the bubbles will indicate the puncture site. If the camera is intact, the problem is in the tire, examine it from the inside for objects sticking out.

If nothing works, try a camera sealant (like Slime) that fills up the micropunctures and prolongs the life of the camera.

1. Lower the wheel and take off the nipple.
2. Pour 60-100 ml of sealant inside the chamber through the nipple.
3. Pump the wheel and scroll it so that the sealant is evenly distributed.

Scooter assembly and final inspections

Once the camera is successfully replaced, it is just as important to put the scooter back together, because improper assembly can cause the motor or brakes to break.

1. Set the wheel on the axle: Carefully put the wheel on the axle, aligning the holes. Tighten the nuts with the key on the axle. 10 mm 13 mm for Mi 3/4). Make sure the wheel rotates freely, without backlashes.
2. Connect the motor: combine the motor connector with the controller (on the M365/Pro He's alone, make no mistake — 5–7 N).
3. Set the brake disc: Make sure the disc is not touching the brake pads. Tighten the bolts cross-to-cross so that the disc sits flat.
4. Connect the battery: Insert the plug into the controller (on the M365/Pro) Or fix the battery (on the Pro) 2/3 Lite.Put the scooter on and check that the engine is running (lift the rear wheel and press the gas).

Final check:

• 🔹 Ride 100-200 meters at low speed, listening to outside sounds.
• 🔹 Check the brakes – they should work smoothly, without creaking.
• 🔹 Inspect the wheel after the trip - there should be no traces of friction on the frame.

⚠️ Warning: If the scooter is not driving after assembly or if it gives an error (for example, the Error 15 on the Pro 2), check the connection of the motor. Often the problem is oxidized contacts - clean them with a stripe or alcohol.
