Steel frame electric bicycles, processing performance, chromium-molybdenum steel is the oldest bicycle materials, the longest of its research, the processing technology has been developed to a very stable level. 2. Strength According to the conclusion of the car, it can be concluded that car enthusiasts can draw the conclusion that the strength of the same volume steel is much larger than that of aluminum alloy and titanium alloy, so the strength of qualified steel frame can be reassuring. 3. Take a comfortable, good steel elastic steel made of metal, can absorb the vibration when riding. Therefore, the steel frame will not be as uncomfortable as the aluminum frame, especially for the travel frame. 4. Steel metal fatigue stronger than aluminum, so the same conditions of use, the life of the aluminum frame longer life. Of course, the steel frame also has its insurmountable shortcomings: 1. Light weight, today in the pursuit of lightweight equipment, the quality of 7.8g / cm3 steel so that everyone does not encourage him. Although light steel construction, while pumping pumping technology wall is very thin, but the weight of the steel is difficult to reduce to 1600 grams or less. Many aluminum frame weighs only about 1400 grams. This is a competitive framework, rarely seen the reasons for the steel frame. 2. Rusted, relative to other materials, steel is relatively easy to rust. Rust can drastically reduce the strength of the steel, shortening its service life. (Such as BEARS these frames in order to prevent the problem of rust to the framework of the new tube coating), so we must take various measures to prevent rust.
