How to Fix a Rubbing Wheel on a Xiaomi Electric Scooter

A rubbing wheel on your Xiaomi electric scooter can be an annoying issue that affects your ride's efficiency and smoothness. In this article, we will walk you through the steps to identify the cause and provide a solution for fixing a rubbing wheel on a Xiaomi electric scooter.

Step 1: Identify the Cause
There could be various reasons behind the rubbing wheel, such as misaligned calipers, bent or warped disc, loose bolts, or damaged bearings. Carefully examine your scooter wheel and try to pinpoint the issue.

Step 2: Fixing Misaligned Calipers
If your scooter has disk brakes, a common cause for rubbing can be misaligned calipers. To fix this, loosen the two bolts that hold the caliper to the fork or rear dropouts. Squeeze the brake lever to center the caliper over the rotor, and retighten the bolts while holding the brake lever.

Step 3: Straightening a Bent or Warped Disc
If your disc is bent or warped, you can try to gently straighten it using an adjustable spanner. Begin by slowly turning the wheel and identifying the exact position where the disc rubs against the brake pads. Gently bend the disc back into shape with the spanner. You may need to repeat this process a few times to achieve optimal results.

Step 4: Tightening Loose Bolts
Loose bolts can cause misalignment and rubbing in the wheel. Ensure all bolts are tightened appropriately, including the axle bolts, caliper bolts, and rotor bolts.

Step 5: Inspecting and Replacing Damaged Bearings
Damaged bearings can cause a rubbing wheel on your scooter. Inspect the bearings for any signs of damage, rust, or wear. If you spot anything unusual, it’s best to replace the bearings to prevent further issues with your scooter's performance.

Remember always to use safety gear, such as gloves and eye protection, when working on your electric scooter. If you're unsure about performing any of these steps yourself, or the problem persists, it’s advised to consult a professional mechanic for assistance.
