答案
A life-changing invention
Before bicycles were invented, people had problems moving around quickly for short trips. Walking was slow and tiring, and riding a horse was a bit risky.
The first bicycle-like thing had no pedals. People had to push their feet against the ground to move. Then, around 1863, a man from France added pedals to the front wheel. After that, inventors kept improving it. By the late 1890s, the modern bicycle was ready for use.
In my view, the invention of the bicycle is good for the environment. Riding it keeps me fit. And it is not expensive, too. I'm thankful to the inventors for this great invention.
