From which part does the traditional 28 bicycle get its name?

The traditional 28 bicycle gets its name from its wheels.

The wheel diameter of the 28 bicycle is 28 inches, which is why it is called the 28 bicycle.

Compared with modern bicycles, its wheel diameter is larger, the body is longer, and the ride is more stable.

Moreover, the frame structure of the Erba bicycle is stronger and can bear greater weight, making it very suitable for traveling with heavy loads.

In addition, the chain and gear design of the 28 bicycle are more reasonable.

Erba bicycle, as a type of bicycle with a long history, has many irreplaceable advantages.

This kind of bicycle was very popular in the 1950s and 1960s because of its size and design, and even became a unique memory of that generation.

It could be seen all over the streets of that era and became a symbol of that time. The frame components were the basic structure of the 28 bicycle.

The design principle of the traditional 28 bicycle: Since the 28 bicycle relies on the human body's own driving force and riding skills to travel, the frame is responsible for withstanding the impact load generated by the 28 bicycle while driving and whether it can be comfortable and safe.

The ground is an important structure for carrying the human body. The manufacturing precision of frame components will directly affect the safety, stability and briskness of riding. Generally, the spokes are of equal diameter in order to reduce gravity.

There are two types of tires: soft-sided tires and hard-sided tires. The soft-sided tires have a wider cross-section and can completely wrap the inner tube. They have a relatively large ground area and are suitable for driving on a variety of roads.

Hard-sided tires are light in weight and have a small landing area, making them suitable for driving on flat roads. They have the advantages of low resistance and brisk driving.

The pattern on the tire is to increase friction with the ground, and the pedal components are assembled on the left and right cranks of the central axis component.
