A drop of water can reflect the sun's rays. The key components of an adult car can also bring about changes in the entire bicycle industry.
At the 2021 Shanghai Bicycle Show, Daxing's newly launched sharing technology accessories products attracted much attention, among which "Safety Disc Brake" won the Innovation Gold Award.
On December 3rd, Dr. Han, chairman of Dahang Group, announced the launch of "Revolutionary Double Brake" at the new product launch conference of the China Bicycle Industry Conference, and introduced the innovative advantages of these two disc brakes in detail, which caused a sensation in the industry, industry insiders have inquired about prices, procurement intentions are strong, after the meeting, Dahang and multi-party partners have been contacted.

Safety disc brake
The safety disc brake has been perfectly optimized for the existing disc brakes on the market, realizing the internal offset of disc discs and disc brakes, and perfectly solving the safety hazards of ordinary disc brakes.
Its flower drum disc mounting surface adopts a customized internal bias structure, the width of the front and rear forks of the frame maintains the standard requirements on the market, increases the versatility, reduces the cost of mold development; the flower drum can be achieved by adjusting the machining on the basis of the original blank (internal offset of 13 to 15mm), the disc brake blade is as close as possible to the wheel, and the internal shift distance is up to 15 mm, which is lighter than that of ordinary disc brake.
The disc brake test meets the requirements of GB/T19994-2005 and GB/T23264-2020 standards.
The internal offset internal structure effectively protects the disc discs from impact when falling.
For some models, the disc brake is effectively improved to achieve flatness.
Its raised fixing position design reduces the risk of disc brake rubbing. It adopts a two-piece locking type, and has a slope on one side, which is compact, and the spoke side is equipped with a concave and convex edge, which has a good heat dissipation function.
Revolutionary double brake
The revolutionary double brake is mainly composed of brake seat, brake body, first brake pad, second brake pad and elastic part.
When in use, the brake body drives the first brake pad, moving in the direction close to the disc brake disc, which can act on the disc brake disc in the opposite direction of the second brake pad, and the same size of force acts on the disc brake disc to achieve the function of braking. Compared with the fixed situation between the brake body and the brake seat in the existing technology, the deformation of the disc brake disc is reduced and the service life of the disc brake disc is improved. At the same time, the elastic parts facilitate the reset when the force between the brake body and the brake seat is applied. Achieving a single brake is equal to a double-sided brake effect and is lighter in weight. Applicable to the market of all categories of disc brake modification, greatly reducing the cost, its cost performance is high, bringing about the revolution of innovation and development of double brake products.
Size straight-headed folder
In addition, Dahang has also developed "big and small smooth head" folder bicycle spare parts, which are adapted to different specifications of folding electric/electric assist models on the market.
▲ Big Shuntou
▲ Small smooth head
"Size smooth head" is made of aviation aluminum material, the structure is simple and beautiful, the strength is high, the weight is light, the operation is smoother, and the stability is higher.
It is made by the one-piece molding extrusion process and CNC high-precision grinding process, the front and rear shell locking, the positioning between the folding end of the bicycle is fast and precise, the welding strength is high and the fastness of the folder itself is high, which will not bring great safety risks to the cyclist.
The folder handle is wider than the general folder handle, the middle of the handle is provided with a lock hole corresponding to the lock lever, the interior is hollow, the upper lock hole and the lower lock hole are matched, just one action, you can achieve the second opening second lock.
In addition, its biggest highlight is that the folder and the folding body with the welded inner side of the frame tube, can perfectly hide the battery in the frame, in order to effectively save space, improve space utilization, reasonable and clever design.
Innovation to revitalize enterprises, share the industry. In recent years, in addition to leading the industry in folding vehicles, Dahang Group has also exerted its own scientific research advantages, and has carried out in-depth cooperation with dozens of trading companies, car manufacturers, frame factories, parts factories and other bicycle (including electric) counterparts in terms of technology sharing, parts sharing, brand sharing, etc., and achieved extraordinary results. Here, Dahang Group sincerely welcomes major bicycle companies to negotiate business and discuss development plans!
