As the skeleton of the entire Electric Bicycle, the Bike Frame determines and affects the correctness and comfort of the riding posture to the greatest extent.
The Electric Bike Frame material evolved from the earliest chromium molybdenum steel to aluminum alloy, followed by the use of composite materials such as carbon fiber, as well as scandium alloy, magnesium alloy, titanium alloy, etc,The industry continuously develops new material formulas, improves the design capabilities of pipe fittings and structures, and innovates processing technologies, in order to make the frame lighter, stronger, more comfortable, and more streamlined and beautiful. Density is one of the key factors determining the weight of the E Bike frame. The lower the density, the lighter the frame can be. The density of chromium molybdenum steel is 7.9, aluminum alloy is 2.6-2.9, titanium is 4.5, titanium alloy is 4.3-5.1, carbon fiber composite is 1.6, and magnesium alloy is 1.7. Therefore, it can be seen that chromium molybdenum steel has the highest density and carbon fiber composite is the lowest. However, in addition to weight, the frame also needs to consider tensile strength, elastic coefficient, etc., so although the density is low, insufficient strength is not enough.
At present, there are several main materials that can be used to manufacture Electric Bicycle frames: steel, aluminum alloy, titanium alloy, magnesium alloy, scandium alloy, carbon fiber, etc. Generally, the frames appearing in the market mainly include steel, aluminum alloy, titanium alloy, and carbon fiber. Scandium alloy and magnesium alloy are recent eme
