Recommended models of bicycles: F880, Y1, Y2
 
The permanent brand bicycle can be traced back to 1940 and became a household name in China in the seventies and eighties. Bicycles, as the three major pieces in the past, are equivalent to today's cars, and the permanent bicycle with two or eight bars has left an impression of sturdiness and durability for the older generation.
 
No matter which category of bicycles, the two time-honored brands in Shanghai, Forever and Phoenix, are mostly on the same footing, and the products are-for-tat, which can be well compared and selected horizontally. Similar bike brands include Lightning and Trek, Giant and Merida. The sales volume of permanent strollers is second only to Phoenix, and the most competitive product, F880 magnesium alloy children's bicycle, is also made of a one-piece magnesium alloy inner wiring frame, with exquisite aluminum alloy wheels, weighing only 8.6 kg, and there are many choices for color matching and coating, and the price of more than 400 yuan is benchmarked against the Phoenix "Space Speed", and the cost performance of both is very outstanding.
 
Permanently reduce the price of aluminum alloy strollers to more than 300 yuan, aluminum alloy F550, F540 are more than 300 yuan, but the weight reaches 10 kilograms, which is no different from carbon steel models, and does not give full play to the advantages of aluminum alloy materials. There is also a car that claims to be made of polymer composite materials (plastic) that is very eye-catching, but the weight is also not ideal, and the plastic will also have the problem of aging, and it is not as durable as metal. On the contrary, the carbon steel models with a price of two or three hundred yuan are more realistic, such as Y1, Y2, etc., the modeling and decoration are very rich, and the individual colors also add Transformers movie elements, which has a strong attraction to children.
 
Permanent models are also recommended for online shopping, the categories and sizes on the Internet are more complete, and the discounts are larger, and the pumps, fenders, bells and other accessories that are sent when buying a car are also very practical.
