It is understood that magnesium alloys have low density, specific stiffness, high strength, good damping characteristics. It has been applied in the aerospace, automotive, motorcycle, electric power bicycle industry. Nowadays, the amount of magnesium used in every car has been one of the advanced criteria to measure the field of cars and other vehicles: Europe and the U.S. use of magnesium alloy parts per vehicle range from 5.8 to 23.6 kilograms, the amount of china is less than 10 kg bicycle car. With the trend of light and convenient recent years, China's electric power bicycle industry also increasingly using the amount of magnesium alloys.
It is considered the lightweight trend, electric power bike companies embarked on magnesium alloy application in experiments on the electric power bicycle quite a few years ago, and has made a major breakthrough. Part of the electric power bike market has begun to adopt a lightweight magnesium alloy and other metals as a frame currently.
