We are concerned about Bike Frame materials because the quality and characteristics of different materials vary greatly. If you want to own an ultra light road vehicle, you may choose a carbon fiber frame. But sometimes, the lightest carbon cars may not have as much durability as lower gear Electric Bicycles. There are also trade-offs and trade-offs in the design and manufacturing of the Bike Frame.
Tools/raw materials(Aluminum, carbon, titanium, steel)
Considerations:
1)Cost: Usually the primary factor. However, there is also a certain price range for each material, which is basically a penny for a penny. If the price is outrageously low, it is estimated that there is a problem with the quality, and there is basically no need to consider it.
2)Durability: Usually the second largest factor. Although our budget may not be high, we don't want to buy a bicycle that won't last long.
3)Hardness: What we are talking about here is the deformation of the material. Generally speaking, the harder the material, the lower the deformation, and the higher the efficiency of force transmission. The softer the material, the greater the deformation, the better the shock absorption effect, but at the same time, the efficiency of force transmission decreases (unloading). This may seriously affect the quality of cycling.
4)Weight: Each material of the same quality has a similar frame weight. Of course, you can buy a very lightweight Ebike Frame, but if the other components are heavy, the advantage no longer exists. Therefore, if you are concerned about weight, you should focus on the weight of the entire vehicle, not on a specific part.
Comparative analysis of the performance of four frame materials.
1)Aluminium
This is currently the most common material, especially for entry-level lightweight racing and fitness bicycles, because aluminum (alloy) has good handling, acceleration, and climbing ability. However, its vibration absorption is average and is the most uncomfortable among existing materials. Manufacturers often use carbon fiber with aluminum alloy to slightly improve vibration absorption. Many aluminum alloy Electric Road Bike is equipped with carbon fiber front forks.
2)Carbon Fibre
Carbon fiber is a magical material. It is not a metal, but a layer of carbon cloth bonded and heated. According to the number and shape of layers of carbon cloth, the diameter of frame pipes, and the weaving method of carbon cloth, the frame may have high strength or good vibration absorption in a certain part or direction. High quality carbon fiber has very high durability, but some manufacturers cut materials in pursuit of lightweight, but naturally it is also prone to breakage. Like other materials, their quality is also reflected in their price.
3)Steel
Electric Road Bicycles have been using steel as a metal since their birth. To this day, many people still have a particular fondness for steel frame cars. Although current technology can produce lighter and better frames, it is not perfect either. Steel frame vehicles may experience slight deformation when loaded. This characteristic gives cyclists a feeling of sitting on a spring, with excellent vibration absorption but also absorbing stepping force. The hardness of very high-quality steel is second only to carbon fiber.
4)Titanium
Titanium metal (Ti) is also a technology based material that was relatively late in use on Electric Bicycles. It is very light, strong, and durable, making it the most elastic of all bicycle frame materials. Although it has high strength, it is easy to deform, and the rebound force will give you a sense of acceleration. The usual formula for titanium alloy pipe material is aluminum 3% vanadium 2.5%, while the alloy formula for some small parts is harder 6% aluminum and 4% vanadium. The hardness of titanium metal is sufficient to prevent bullets. Then, once damaged, the repair cost is also quite expensive.
