How do Baby Walking Bike ensure that they are noiseless when used indoors and outdoors?

Baby Walking Bike ensure that they are noiseless when used indoors and outdoors by adopting silent wheel design, optimizing materials and structures, focusing on bearings and lubrication, paying attention to design details, and ensuring weight and balance. This design is specifically reflected in the following aspects:
Material and structure: The core of silent wheels lies in the fine selection of materials and the ingenious design of structures. Highly elastic materials, such as high-quality rubber or high-tech synthetic rubber, not only have good wear resistance, but also effectively absorb and disperse impact force during rolling, reduce vibration waves generated by direct collision with the ground, and thus suppress the generation of noise. These materials are selected based on their ability to suppress sound conduction, ensuring low-noise operation on a variety of ground materials, such as wooden floors, tiles or outdoor grass. In terms of internal structure, silent wheels are precisely calculated and optimized to reduce unnecessary friction points. For example, a streamlined wheel hub design is adopted to reduce air resistance and friction between the bearing seat; at the same time, the connection between the tire and the wheel hub also adopts low-noise sealing technology to prevent internal parts from loosening or abnormal noise. In addition, some high-end silent wheels will also add a layer of sound-absorbing material to further absorb and isolate noise.
Bearings and lubrication: As the core component of the silent wheel rotation, the quality and processing accuracy of the bearing directly affect the noise level. The use of precision-machined bearings, combined with high-quality steel or ceramic materials, can ensure that the bearings still maintain extremely low friction and vibration at high speeds. In addition, regularly adding an appropriate amount of lubricant to the bearings, such as high-performance grease, can not only reduce friction, but also form a protective film to prevent direct contact between metals, thereby extending the life of the bearings and reducing noise.
Design details: The design details of the silent wheel should not be ignored. The wide tread design not only increases the contact area with the ground, improves grip and stability, but also more effectively disperses the pressure of the tire on the ground and reduces the noise generated by single-point impact. Specific pattern designs can be optimized according to the characteristics of different ground surfaces, such as adding drainage grooves on slippery ground, or using fine patterns on hard roads to increase friction, which can reduce noise to varying degrees.
Weight and balance: The overall weight and balance of the baby walker are important for the silent effect. Being too heavy or too light may cause the walker to shake or bump unnecessarily during movement, which in turn increases noise. Therefore, designers will make precise weight distribution and balance designs based on factors such as the purpose of the walker, the target user group, and the use environment. For example, by adjusting the frame structure, strengthening key connection parts, or using lightweight and high-strength materials, the walker can maintain a stable posture when stationary and moving, reducing the noise caused by shaking.
Testing and Verification: During the production process, Baby Walking Bike and their silent wheels will undergo a series of rigorous testing and verification procedures. These tests include but are not limited to noise testing, durability testing, stability testing, and safety testing. Noise testing will be conducted in various simulated actual usage scenarios to evaluate whether the quietness of the walker meets the relevant standards and requirements.
