Bicycle, a useful means of transport we use every day. Most of us use a bicycle at least once in our life, but most of us can’t fully understand the history of its birth and history.
The development of bicycles is full of ups and downs. There are many theories and interesting stories about who first laid the foundation for the creation of the bicycle. And who contributed to it, improving and perfecting the bicycle as it is now.
The year 1790, 232 years ago. Count Sivrac, a famous inventor who invented the bicycle. The shape of the bicycle at that time was quite strange. It looked like a moving toy. Although not really having real traffic value.This invention was the premise for the later development of bicycles. At that time, the owners of this machine were people of high rank and position in society.
Until 1813, Baron Karl Friedrich Drais greatly improved the shape of the bicycle. Making it able to change direction more flexibly. The structure of the bike was two wheels lined up on a wooden frame and no pedals. The person sitting on the bike pushed his own legs so that the bicycle could move forward. The control became easier. However, at this time, the bicycle was still just a toy, like a balance bicycle of kids now.
Kirkpatrick MacMillan, a Scottish black smith was the inventor of the first mechanically propelled two-wheeler bicycle in 1839, although this claim was often disputed.
Only after two brothers Ernest Michaux and Pierre improved the bike, adding pedals and crankshafts close to the two wheels, the bicycle did become a real form of transportation. At this time, the bicycle had a shape. The shape was similar to the current bicycle and has the official name as bicycle.
The greatest development time history of the bicycle
The period of the greatest development of bicycles began in 1870 at the same time as the advancement of metallurgy technology. People created bicycles with sturdy metal frames, able to withstand large loads. In addition, hard rubber became the main material of tires, so the bicycle could move at a fast speed, up to 24 km / h. This was the invention of two inventors Ernest Michaux and Pierre.
Ten years later, Harry John Lawson had made a spectacular revolution. The bicycle was completely transformed with a new design. The chain connecting the rear wheel to the front wheel axle made the bike move much smoother and safer. At the same time, people produced massive bicycles in the United States.
In the following years, inventors gradually perfected bicycles. It had hollow metal frames, which made the frame light but bicycles were strong enough to carry goods. Tires were made from soft rubber, which was inflated with compressed air.It made bikes move faster on bumpy roads.Bicycles had also brakes, discs, and cassettes. Bicycles at this time already had basic features and became a popular means of transport at that time.
Over two hundred years of history, in order to have a bicycle as convenient and useful as it is today, many inventors have had to put in a lot of effort, dedicated both brains and hearts to create it out.
The structure of the bicycle and how the modern bicycle works:
The bicycle has components: the control system, the transmission system, and the conveying system.
Control system:
+ The handlebar is structured with 2 handles, connecting the movement thanks to two ball bearings located in the middle of the neck shaft, helping the driver to easily turn the car left or right.
+ The brake is an important part of the car. It is mounted right on the handlebar including the transmission line and brake pads. When there is a problem that requires urgent braking, the riders will squeeze the brake, immediately the brake pads on both sides of the wheel will press against the wheel to create a strong friction, which will cause the bikes to slow down or stop completely.
Transmission system:
Includes pedals, chassis, centre axle, center ball bearing, chain, cassette, 2 axles, ball bearings and wheels. When the user sits on the saddle, the handlebar handle, the foot pedal will make the axle move in conjunction with the disc to follow and make the chain part rotate the gear system and the rear wheel. force to propel the vehicle forward.
Conveying system:
Including saddle, cart, three-station stand (cargo pass unit). On the frame the saddle.There is a seat port so the riders can sit comfortably . On the rear axle,there is a pannier rack so it can carry one person, a baby or different items. The bikes also have a storage basket above the front wheel.
Touring sports bikes or city bikes are often having a front and rear fender system to prevent mud from rain.It also have a dynamo-powered lighting system at the front of the fork, and a bell as well as other accessories
While other vehicles all use raw materials such as gasoline to create energy to help the engine move, but at the same time, it also generates emissions that pollute the environment, affecting human health.
Benefits
Bicycles will always be a useful and environmentally friendly means of transport. They cause no pollution, no emissions. In the future, bicycles will be able to become a popular means of transport in big cities. gradually replace cars, helping people to be more active and get healthier.
Now it’s not just about helping us get around easily. Bicycles are also very useful as means of exercise and sports.
In a short time of just over 200 years, at the beginning of the 21st century. There are more than 1 billion bicycles in the world. This number far exceeds the number of cars, both in total number and in number of models.
Currently, there are bicycles with many different types, suitable for many different terrain conditions, for all ages.
From the initial simple designs, we can see many bikes as classic bikes, mountain bikes, hybrid bikes, BMX, city bikes, Road bikes and electric bikes, folding electric bikes, scooters and more.
