The prevalence of magnesium alloy frames over aluminum alloy frames in the electric assist bicycle market can be attributed to several factors:
1.Weight Advantage: Magnesium alloys are lighter than aluminum alloys, which is beneficial for electric assist bicycles as reducing frame weight can
improve performance, increase range, and reduce battery consumption.
2.Damping Properties: Magnesium alloys have good vibration absorption characteristics, providing a more comfortable riding experience by reducing
the impact of uneven road surfaces.
3.Design Flexibility: Magnesium alloys exhibit excellent fluidity during thermoforming processes like die casting, meaning they can be molded into
complex shapes, offering designers a greater degree of freedom.
4.Environmental Impact: Manufacturing components from magnesium alloy typically requires less energy, and due to its lower melting point, the
processing emits less carbon dioxide, making the use of magnesium alloy potentially more attractive from an environmental and energy consumption standpoint.
5.Reduced Costs: Although magnesium alloy traditionally costs more than aluminum alloy, improvements in production technology and economies of scale
have reduced the cost of magnesium alloy, making it more price-competitive.
Despite this, aluminum alloys are still widely utilized for electric assist bicycle frames due to their corrosion resistance, high strength, and cost-efficiency.
The choice between the two materials will vary depending on the manufacturer's target market, cost structure, and technical capabilities. In some cases,
manufacturers might opt for magnesium alloy to achieve specific performance goals or use it as a selling point, whereas in other cases, aluminum alloy may
be the superior choice.
