The quality of a cart mainly depends on the wheels and frame. Which is better, aluminum alloy or carbon steel, depends on the thickness and surface treatment of the material. Aluminum is light and oxidation-resistant, and carbon steel is easy to rust and corrode if it is not electroplated well. However, if the profile is too thin, the aluminum material will be easily deformed. First, choose a stroller according to the road conditions. If the road conditions are good and the road surface is flat without many potholes, you can choose a stroller with general shock absorption performance; If the road conditions are not smooth, bumpy and bumpy, it is necessary to choose a stroller with good shock absorption performance, such as a stroller with independent wheels for high landscape, a stroller with pneumatic tires, and even a stroller with independent wheels for pneumatic tires, which can meet the needs of babies traveling in this road condition.

Generally speaking, the components of baby carriages are high carbon steel or aluminum alloy, PV materials and so on. As far as strollers are concerned, products made of high carbon steel are of better quality. On the one hand, the stroller made of high carbon steel has good stability, because the stroller made of this material is biased;

On the other hand, the stroller made of high carbon steel is more durable and has better shock absorption effect. The aluminum stroller is light, but the body is not heavy enough, so if the road is bumpy, the baby will feel uncomfortable. At the same time, the stability will be relatively poor. But this kind of stroller has another advantage, that is, it is easy to carry. So which one is better depends on the needs of parents and babies. If stability is more important, it is recommended to use a high carbon steel stroller; If portability is important, you can consider buying a stroller made of aluminum alloy.
