Tern is a rookie in the international folding car industry, its founder Mr. Han Anshi's father is the founder of the folding car leading brand "Daxing" Dr. Han Dewei, and its R&D and operation team is mostly from Daxing, you can see many patented designs of Daxing on Tern's folding cars, but the overall positioning of Tern folding cars is higher than that of Daxing, just like "Lexus" to "Toyota", the price is from more than 2000 to 20000 yuan, the original intention of the brand is to create a folding car that is as light as a tern and can travel long distances.
 
The whole Tern series adopts the common folding method of folding the middle section of the girder in half, which is a decent performance. There are three series on sale: Link, Verge, and Eclipse. The Link is a K-frame model similar to the Daxing P8, which is the entry-level model of the Tern, positioned for commuting and leisure; The most representative of the Tern is the Verge series, which is positioned as a high-strength and high-performance series, and is its competitive main car series; The Eclipse series is a 24-inch and 26-inch folding car with large wheels, which can be seen as a large Verge.
 
The design of the Verge's frame is similar to that of the P-frame of the big row, using the bow girder, which is a stronger design than the straight beam of the K-frame of the big row, a simple analysis: the two wheels provide upward support at both ends of the frame, and the weight of the person and the pedaling force are applied downward in the middle of the girder, as if breaking a chopstick, in response to such a stressed structure, the bow girder can provide higher rigidity than the straight beam under the same pipe material. The higher rigidity also allows the pedaling force to be transmitted more directly to the rear wheels, avoiding force loss.
 
The Verge's clean, streamlined shape and frame arc from the two centrally split steel tubes to the rear wheels, like a swallow's rear wing, is known as the "Doubie Truss" 3D dual-structure chainstay, which utilizes the stability of the double triangle. The irregularly curved profiled frame uses a hydroforming process commonly used in automobile chassis. In addition, the whole series adopts a one-piece forged head tube, and is equipped with an OCL folding buckle with a machining accuracy of 50 microns and a strength of more than 50% of the EU standard.
 
The price of the entire Verge series is from more than 3000 to 20000 yuan, and the most worthwhile purchase is undoubtedly the entry-level Verge N8 priced at 3380 yuan in the series, although it is the entry model of the Verge series, but it shares the standard technology of the entire Verge series, the foundation is very good, with good upgrade conditions, and its fine workmanship, excellent frame performance, and 5-year ultra-long warranty are very competitive at this price.
 
The most important thing in the mid-to-high-end folding car is the frame, and the flagship model with a price of more than 10,000 yuan still uses almost the same frame compared to the entry-level N8. At the price of 10,000 yuan, it is facing heavyweight opponents such as "bird car" and "small cloth", which is really like the "Phaeton" car, and the positioning is very embarrassing.
