(Summary description)With the release of the electric folding bicycle, interest in this relatively new travel tool has been aroused, but many people do not know much about this type of electric bicycle, and when they hear the price of an electric bicycle they may wonder: why buy a bicycle that requires pedals when three thousand is enough to buy an electric car? This shows that there are some misconceptions about these products, so today we will talk about the technical principles of electric assist bicycles to give you a better understanding of these products. Although electric bicycles and electric assisted bicycles are both electrically assisted vehicles, it is important to realise that there is a strict distinction between electric assisted bicycles and electric bicycles, so they do not belong to the same category of products. The more direct difference is that an electric bicycle does not have a purely electric mode of riding, but rather requires a 'human + electric' hybrid drive, which is fundamentally different from the purely electric mode of an electric car, and the way you ride such a vehicle is no different to riding a bicycle. The electric power provides a solution to the problem of cycling effort, and with the human power, it is possible to go beyond the range of a typical electric bicycle with a modest battery, enabling longer distances to be travelled. The core power technology of electric bicycles Firstly, the electric bicycle was first developed in Japan and uses the 'Power Assist System', a torque sensor-based hybrid power system that can be driven by human power and electricity. It can also be driven by human power alone. The Power Assist bicycle is a personal vehicle that offers the lightness and convenience of a bicycle, while compensating for the burden of cycling up hills, into windy conditions and when carrying loads. It is based on a conventional bicycle and is equipped with a torque sensor-based power system with motor and battery. The main difference from an e-bike (e-donkey) is that instead of adjusting the amount of power through the handlebars, it uses torque sensors to sense how hard the rider is pedalling and, depending on the amount of human effort, to provide the rider with the appropriate power support. At present there are many companies with power assist systems worldwide, but there are only a few that use torque sensors in their power assist systems, such as Bosch and Maha in Germany, Yamaha and Panasonic in Japan. These companies are basically related to the automotive and new energy industries and have a very high technology development threshold, making it difficult for general companies to enter.
