In 1817, a German inventor named Karl von Dres created the first two-wheeled vehicle.

It was made wood and had no pedals.

To move, the rider had to push their feet against the ground, similar to running while sitting down.

People called this machine the dandy horse.

In the 1860s, French inventors added pedals to the front wheel.

This new design was called the Vlasipad.

However, because the wheels were made of iron and wood, riding on bumpy cobblestone roads was extremely uncomfortable.

People started calling it the Bone Shaker.

By the late 1870s, the high-wheel bicycle became popular.

It had a giant front wheel and a very small back wheel.
12
Riders sat high up, which allowed them to travel faster.
13
However, it was dangerous because riders could easily fall forward over the handlebars.

Finally, in 1885, John Kemp Starley invented the safety bicycle.

It featured two wheels of equal size, a chain drive connected to the rear wheel, and rubber tyres filled with air.

This design made cycling safe, comfortable, and accessible to everyone, including women.

Today, modern bicycles still use the basic design created by Starley.

O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
