What Causes the Squeaking Noise at the Rear of a Scooter?

[LaXavier]

Squeaking noises near the rear wheel are generally caused by worn brake pads or issues with the rear wheel bearings. Internal wear or rust in the pulley, as well as poor lubrication, can also produce sounds, though these typically don't result in squeaking. It's advisable to first inspect the rear brakes and wheel bearings. Related explanations are as follows: 1. Normal phenomenon: When starting the engine, especially in cold temperatures, the engine may run unevenly due to low temperature, which is a relatively normal occurrence. Additionally, during cold starts, the engine oil hasn't fully lubricated the components. Accelerating immediately in this state can increase engine wear. 2. Warm-up: After starting, it's recommended to let the engine warm up idly until it reaches operating temperature and the throttle responds smoothly before riding. This prevents throttle hesitation and significantly reduces wear during cold starts, which is crucial for minimizing engine failure rates and extending its service life.
