Cycling is a happy and healthy way to get around and is especially popular.

It has been more than 200 years since the world's first bicycle was introduced.

The first bicycle was invented in the late 18th century by the Frenchman Siva.

The earliest bicycle was made of wood and had a simple structure, with no drive or steering device.

Even so, when Sivrac rode the bicycle to the park for a ride, the people present were amazed and impressed.

The world's first truly practical bicycles appeared in the early 19th century.

In 1817, the German Deleuze invented a wooden two-wheeled bicycle with handlebars in Paris, France.

This bicycle still used pedals to move forward, but it could change direction while moving forward, and it attracted a lot of interest.

In 1830, the French government provided letter carriers with bicycles as a means of transportation.

Subsequently, the technology and performance of bicycles continued to be improved.

In 1839, the Englishman Macmillan invented the pedal-powered bicycle, which improved driving speed by eliminating the need to pedal with both feet.

In 1869, the Renault bicycle was born, with the frame made of steel pipe and the vehicle changed to steel rims and spokes with solid tires, making the bicycle more lightweight.

In 1887, the Englishman Lawson completed the design of the chain-driven bicycle.

In the same year, the Englishman Dunlop developed pneumatic tires. From then on, bicycle technology also completed the transformation to commercialization, mass production, and put into the market.

Frame material classification

1. Steel frame: This type of frame is not light in weight, not easy to maintain after a rainy day ride, easy to rust at the weld, and the technology has been eliminated.

2. Aluminum alloy frame: much lighter than steel frame, but the strength has been improved, is now the first choice, but in the welding mouth, the firmness is not perfect.

3. Carbon fiber frame: It is made of a kind of fiber tissue layer by layer winding out the shape of the frame, and glue is added in the process of winding.

4. Nano carbon frame: the diameter of 0.7 nanometers (nm) of nanoscale materials penetrates between the gaps of carbon atoms, to all carbon fiber tissue in the benchmark of molecular bonding for reinforcement.

The frame's impact strength increased by 30%, durability increased by 10%, frame weight was reduced by 15%, and rebound performance increased by 5%!

5. Titanium frame: all welding is done under a sealed vacuum, which is strong and durable for road plug competition bikes.

If you want to buy a bike, it is important to choose a car with good materials and you should make a good selection.
