1. Noise sources and targeted treatment
Motor noise: Low-quality motors are prone to high-frequency howling when running. The noise can be reduced by replacing brushless silent motors (such as rare earth permanent magnet motors with Hall sensors). Such motors run more smoothly and the noise value can be controlled below 55 decibels. At the same time, wrap the motor housing with sound insulation cotton or silicone shock pads to reduce vibration conduction.
Tire friction noise: Narrow tires or under-inflated tires will cause a lot of noise when they rub against the ground. It is recommended to replace them with puncture-proof silent tires with fine patterns and keep the tire pressure at the manufacturer's recommended value (usually 2.5-3.5 bar) to reduce rolling resistance and noise. If there are stones embedded in the tires, they need to be cleaned up in time.
Abnormal noise from mechanical parts: Clicking noises caused by loose connections between the folding shaft and handlebars. Apply Vaseline or silicone-based lubricant regularly, check the tightness of the screws, and tighten them with a wrench (be careful not to over-tighten and damage the threads).
2. Structural optimization and detail processing

Transmission system noise reduction: Chain-driven models are prone to noise due to insufficient lubrication and require the addition of special chain oil every month; belt-driven models require the belt tension to be checked and replaced in time when aging to avoid slipping and abnormal noise.
Brake system adjustment: The friction between the metal brake pad and the wheel hub may produce sharp noise. You can replace the ceramic brake pad or apply a small amount of anti-noise paste on the contact surface of the brake block. At the same time, make sure the brake line is appropriately tight to avoid idling friction.
Shell resonance control: If the plastic parts of the car body resonate due to loose assembly, sound insulation and vibration-damping panels can be pasted at the joints, or sponge strips can be filled to reduce vibration transmission.
3. Usage and maintenance suggestions
Avoid overloading (exceeding the maximum load by more than 10% will increase the motor load and noise), and reduce sudden acceleration and braking operations to reduce mechanical impact noise.
Regularly clean the debris in the motor cooling holes and wheel hub slots to prevent foreign objects from getting entangled and increasing operating noise.
When purchasing, give priority to models marked with "quiet certification". Some high-end products optimize the motor housing shape through fluid mechanics, which can reduce wind noise and mechanical noise from the design source.
