Before the birth of Thundercycle, bicycles have been invented and used for two hundred years.
In the past two hundred years, human beings have been constantly trying to develop the bicycle, and have made many improvements to it. Therefore, it has undergone earth-shaking changes over the years,
and grown into a fully "modern machine".
Today Tundercycle will take stock of those major innovations that have changed the history of bicycle development.
1.Two-wheeled bicycle
Back in the 1800s, bicycles were a symbol of aristocratic status.
Because it is a symbol of nobility, the ornamental value of the bicycle is more important than the practicality, so the Penny- Farthing at that time had a large front wheel and a small rear wheel, which was not only dangerous but also very inconvenient to ride.
To solve this problem,
British engineer Henry J. Lawson improved the original model of the bicycle, and used pedals to transmit power from the pedals to the wheels, and used a chain for transmission.
This chain drive method is still in use today.
2.Pneumatic tires
The tires of the first bicycles were made of strong rubber bands, wrapped around the edges of the rims.
This design seems very simple now, and it has a very big disadvantage--it is not shockproof, so after riding for a long time, People feel a lot of pain in their thighs and heads.
So in 1887, he made the world's first set of pneumatic tires, and later established the Dunlop tire company, but the tires were not removable at that time, so the use-cost was very high.
Made the world's first set of pneumatic tires, and later established the Dunlop tire company, but the tires are not removable, so the cost of use is very high.
Until 1891, Edward Michelin developed a replaceable rubber tire, which later has developed into the prototype of our common tire.
- Helmets
Although the Thundercycle E-bike helmet is more mature now,
bicycles have been without helmets for a long time.
Riders at that time mostly used helmets made of leather. Although this kind of helmet can provide a certain degree of protection for the rider during riding, this protection is only for scratches.
There was not much protection for the impact caused by a crash.
In the 1970s, the helmet in the modern sense appeared for the first time,
MSR and Bell companies in the United States, based on motorcycle helmets and racing helmets, designed a bicycle helmet with ABS plastic as its outer shell and polystyrene foam (EPS) material as its interior filling, which also makes it an industry leader.
That is the helmet we see now.
