History
↓↓
The first bicycle-like invention was the Draisine, created in 1817 by Karl Drais.
It had no pedals—riders pushed off the ground with their feet.
Pedals were added in the 1860s in France, creating the first true bicycles.
The penny-farthing with its large front wheel became popular in the 1870s.
The safety bicycle, invented in the 1880s, resembled modern bikes with equal-sized wheels and a chain drive.
Mass production in the 20th century made bicycles affordable and widespread.
They played key roles in mobility, especially before cars became common.
Today, bicycles continue to evolve with electric models and advanced materials.
