Good morning, everyone. Today, I want to discuss the history of the bicycle. Although many people think the bicycle was invented in the 19th century, early versions appeared much earlier. In 1817, a German inventor named Karl Drais created a wooden, two-wheeled machine called the 'running machine' or 'draisine.' It had no pedals; riders pushed their feet along the ground. Then, in the 1860s, pedals were added to the front wheel in France. However, this design was unsafe because the rider's feet couldn't reach the ground easily. Later, in 1885, the 'safety bicycle' was introduced with a chain drive and two equal-sized wheels, making riding much more stable and popular.
