Good morning, everyone. Today we're going to look at the history of the bicycle. Now, you might think the bicycle is a fairly modern invention, but in fact, the first two-wheeled vehicle, called a 'draisine', was invented in 1817 by a German baron. It had no pedals; you pushed it along with your feet. Then, in the 1860s, pedals were added to the front wheel in France. However, these early bicycles were very uncomfortable because of the solid rubber tires and rough roads. It wasn't until the 1880s that the modern 'safety bicycle' with a chain drive and two equal-sized wheels appeared, making cycling much safer and more popular.
❓ 1880年代に導入された「安全自転車」の主な利点は何でしたか？
A. ソリッドラバータイヤを装着し、乗り心地をより滑らかにしていた。
B. チェーン駆動と同サイズの車輪を備えており、より安全になっていた。
C. それはより軽く、足で押して進めることができた。
D. ペダルが前輪に付いた最初の自転車でした。
✅ 正确答案
It was equipped with a chain drive and equal-sized wheels, making it safer.
