Headquartered in Shenzhen, Xidesheng is currently one of the largest bicycle manufacturers in China, with more advanced material research and development, frame design capabilities, and the industry's first-class carbon fiber, aluminum alloy frame and parts production line, robot welding workshop, dust-free paint workshop. Its manufacturing technology is quite advanced, and it has produced frames for more than ten top international bicycle brands such as Lightning, TREK, and LOOK.
 
Xidesheng did not adopt the tactics of car sea in the field of folding cars, and there are only two models on sale, namely the 14-inch small fold W5 priced at 899 yuan, and the K3 priced at 1999 yuan. Xidesheng does not hesitate to use its many frame manufacturing housekeeping skills to folding cars, and in terms of the product itself, it has a good competitiveness in its price point. The K3 is the P8 Youth Edition of Daxing in terms of price. "I don't know how much better it is to buy Daxing P8 at the price of 2000" is popular among car enthusiasts, which reflects that many car lovers only recognize the brand and do not recognize the product, but in fact, the frame technology used by the K3 has surpassed the relatively old P8.
 
The K3 frame features unequal wall pipe technology, an advanced technology commonly found in road frames and less common on folding bikes. The purpose of this technique is to reduce the weight of the frame while maintaining high strength, by adjusting the thickness of the tube wall according to the distribution of stress on the frame. The bending strength of its hydroformed hexagonal cross-section frame is also better than that of the general elliptical tube frame; The front fork, head tube, riser, and folding mechanism are all built in one piece, reducing many welding parts, and it is very rare to use such a wide range of integrated molding process at the price of 2000 yuan, which also benefits from Xidesheng's mature frame manufacturing experience. The body is designed for internal wiring, and there is no fish-scale weld at the weld using flat welding technology, and the whole vehicle is quite smooth and tidy, and the bow girder with more scientific force is used to achieve a high level of design and craftsmanship.
 
This series of processes with lightweight aluminum, finally implemented, K3 with 10.4 kg of vehicle weight is enough to stand out in the market, 20-inch folding car vehicle in the original configuration is generally 12-15 kg, in the collection of more than 100 models on sale, K3 weight is less than 10,000 yuan within 20 inches of folding car in the lowest. For reference, the P8 youth version in the 2,000 yuan price segment is 14.2 kg, and the P8 aluminum alloy version in the 3,000 yuan price segment is 11.9 kg. Considering that it is still equipped with a heavy mechanical disc brake, its vehicle weight still has room for further reduction.
 
On the whole, Xidesheng bicycle is very cost-effective at the same price, but its folding car product line is not rich enough, giving people the feeling that it is not professional enough in the field of folding cars, Xidesheng also needs to make greater efforts in the field of folding car patents and reputation, establish the professionalism of the brand, so that consumers can be full of confidence when buying Xidesheng folding car products at a price of 2000 yuan.
