Dutch Bike For Sale   Manufacturer explains how to choose a high-quality frame:

1. What is the frame?
The frame is equivalent to the human skeleton, and all kinds of bicycle parts can be installed with the frame. The frame is made of iron, aluminum alloy, and other materials, and the angle formed by the length of the tube affects the characteristics of the overall bicycle. For example, bicycles that ride better in a straight line, bicycles that are easy to turn, and bicycles that are comfortable to ride. Many of these factors are determined by the frame.

2. How can it be considered a good frame?
Lightness, firmness, and flexibility are some of the goals pursued by the frame. In order to achieve this goal, it depends on the craftsmanship of each frame manufacturer. For example, whether the designed frame is designed according to the strength and characteristics of the material, and whether the welding process is mature. These all directly affect the appearance, strength, and elasticity of the frame. The more important thing is to spray paint. A good frame is evenly painted, and spray 3-4 coats of paint. Don't underestimate spray paint, good spray paint can make the bicycle easy to maintain and not easy to rust. If a frame that does not meet the above requirements is used for loading, it is possible to produce a bicycle that cannot ride in a straight line or is difficult to turn or a bicycle that breaks quickly.
