In recent years, the folding bicycles that have appeared on the market have the advantages of small size, light weight, convenient upstairs and downstairs after folding, and can be placed in the trunk of a trolley. More and more people like and accept them, and they are becoming more and more popular. . Compared with ordinary bicycles, a folding bicycle has the characteristics of being foldable. However, because it can be folded, its overall design must meet higher requirements. Since both the supply and demand sides of the production and use of folding bicycles are relatively prosperous, the quality of folding bicycles is also uneven. Many consumers enjoy the convenience of folding bicycles while also experiencing the pain it brings. Ms. Guan Fang from Yunmeng County complained: she bought a “Red Apple” folding bicycle for 280 yuan. Due to the defects in the quality design, the folding buckle would trip by itself and fall while riding, giving her life. Security poses a threat.
Bicycles think the following points should be paid attention to when buying folding bicycles:
1. Observe carefully. First observe whether the surface of the bicycle is smooth, whether there are impurities and obvious color differences, whether there are paint peelings and obvious scratches, and whether the welding process of the frame is exquisite. Look at whether the front fork, frame, and rear fork will rub against each other after the car is folded, because it needs to be folded frequently to prevent the car from becoming slick. Finally, look at the quality of the whole vehicle from the coordination of the frame shape and the main configuration. Stand behind the wheels to see whether the left and right clearances between the tires and the rear triangle of the frame are even; stand behind the wheels to see whether the front and rear wheels are in a straight line on. If both are visually skewed, there must be a problem with this car.
2. Measure with a ruler. Some consumers blindly pursue convenient handling when purchasing, and purchase models with small wheel diameters. As everyone knows, the smaller the wheel diameter of a folding bicycle, the more convenient it is to carry, but the worse the riding effect. The diameter of a better folding bicycle wheel should be between 12 and 20 inches. The 16-inch product is more suitable for short-distance riding, and the 20-inch product is more suitable for long-distance riding. Not only is the riding comfort better than 16 inches, but the frame strength will be higher and the life span will be longer. The effect of riding under 12 inches is very poor. It is recommended to be cautious before buying. At present, there is a folding car with a vehicle diameter of only 6-8 inches on the market. The volume after folding is very small, but it is not feasible for daily use. To ride briskly, the distance from the head tube of the frame to the seat tube is generally 430-530 mm.
3. Hand weighing. From the frame material, there are mainly aluminum and steel. Female. You often need to carry your car up and down the stairs. It is recommended that you use aluminum frame products. Most of these cars weigh about 10 kg, and 20-inch cars generally do not exceed 12.5 kg. Not only is the weight lighter, but the aluminum frame products have a longer lifespan and do not rust. Of course, don’t ignore the strength of the frame. Some manufacturers just make a fuss about the weight. In fact, they reduce the weight by reducing the thickness of the frame material. It is difficult to ensure that the frame has sufficient strength. It is best to ride a few laps on the spot, not only to feel the strength of the frame, but also to test whether the ergonomic design of the whole vehicle is reasonable. A good design can ensure that the riding posture is stretched and will not be fatigued even for long distances.
Fourth, recognize the brand. Since the folding part of the folding bicycle is movable, the corresponding part is required to have firm and reliable performance when riding. The frame must be specially designed to have higher strength than ordinary bicycles. It must be designed and manufactured by a professional manufacturer. In order to pursue high profits, miscellaneous car manufacturers often cut corners in paint, materials, spare parts, and design, and it is difficult to guarantee after-sales service. Therefore, consumers should try their best to choose products from well-known companies to ensure your safety.
The small size and durability and comfort of folding bicycles are often a contradiction that is difficult to reconcile. In order to meet the requirements of consumers, some companies often use consumers to cover up poorly when they don’t know much about folding bicycle technology. On the other hand, when consumers are shopping, they must observe more, think carefully, shop around, weigh the pros and cons, in order to buy the desired products.
