Magnesium alloy is good.
Magnesium alloy is a lightweight and high-strength material with excellent mechanical properties and corrosion resistance. Balance bikes made of magnesium alloy are lightweight and easy to carry and operate. Magnesium alloy also has good impact resistance and wear resistance, which can effectively extend the service life of the balancing vehicle. In comparison, nylon material is relatively light, but has poor strength and wear resistance, and is easily damaged by external forces. All things considered, magnesium alloy is superior in terms of lightweight, strength and durability, so a balance bike made of magnesium alloy is better.
