What are the differences between Feige, Forever, Giant, Trek, Merida, and Phoenix bicycle brands?

Trek, Giant, and Merida are well-known international first-line brands. Their main products are entertainment-level and competition-level road bikes, hard-tail mountain bikes, and soft-tail mountain bikes. They compete in the three major tours (ie. The Tour de France, the Giro d'Italia, the Vuelta a Espa?a, and the three major Tours represent the highest level of road cycling sports in the world) and UCI international professional mountain bike events (represented by the World Cup, World Championships, Olympic Games, and U23 Youth Cup) , not only have sponsorship and their own title teams, but also have these international professional players participate in the design and research and development, so they are in a leading position in technology, such as Trek, whose 29-inch FUEL? EX9 series soft-tail mountain bike in 2017 has the highest geometry The design achieved a breakthrough, improving the control performance of 29-inch to the level of 27.5-inch (previously, the control performance of 29-inch was not as good as 27.5-inch); Giant is the first in the world to apply aviation-grade wind tunnel equipment to the research and development of frame aerodynamic structure. One of the results of the two major front-line companies in China (the other one is Lightning) is the Propel series of road bikes. In addition to professionals in the three major tours, it also has a high reputation among riding friends; Merida will not be long-winded, and it is currently Lightning. The major shareholder of the company (Lightning and Trek are both equal, and were later acquired by Merida). For details of its many series and models of road bikes and mountain bikes, you can go to Merida’s two official websites (namely, those with suffix .cn and suffix .tw, Taiwan There are more models on the official website). In addition, Giant, Merida, Buwei and Daukas are four powerful bicycle manufacturing companies in Taiwan (known as the "four major bicycle manufacturers in the world" in the industry, including Trek, Lightning, Cannondale, LOOK, Most of the mid-to-high-end models of international first-tier brands such as Scott are manufactured by these four OEMs). . . Feige, Forever, and Phoenix were once the first-line well-known bicycle brands in mainland China (from 1950 to 1990). However, with the entry of some international first-line brands in the 1990s (first of all, the British Amini, the American Daimyo, and Taiwan's Giant Merida) , under the combined impact of their advanced ideas, design, craftsmanship and quality control, as well as many new bicycle models, several once-splendid domestic brands have gradually fallen behind. In 1990, when the Beijing Department Store first entered mountain bikes ("Spotz "Man" brand, the American brand Sportsman introduced by Anshan) and Feige Forever Phoenix are still producing traditional 26-inch and 28-inch old-fashioned bicycles (that is, imitating the structure of the British "Lanling" since the 1950s). Now take Giant as an example. In addition to various hard-tail series, mid-to-high-end mountain bikes also have four major soft-tail series (Among them, the AM-level soft-tail STRANCE?2 has won the "Best Value for Money" award several times in the UK and North America). There are many models of top-level “team editions” (i.e. models used by teams for world-class competitions) priced from entry-level 1,000 yuan to tens of thousands of yuan, while Feige Phoenix Forever is still only an entry-level hardtail mountain bike (priced at several yuan). 100 to 1,000 yuan), lagging far behind in many aspects. . . .
