问题     What did the first bicycles look like? The earliest bicycles were called "running machines". The rider sat on the seat of the "machine" and pushed it with his feet. The rider ran with his feet but the wheels of the bicycle helped him to go very, fast. These bicycles went faster than a running man but they were very uncomfortable. The wheels were iron and in those days the roads had many holes and big stones.
    There was another kind of old bicycle with a big wheel in the front and a small one behind. People called these bicycles "Penny Farthings". In England, many years ago, there were two coins called a penny and a farthing. The farthing was about a quarter of the size of a penny.
    The big wheel had pedals. The rider sat on the seat at the top of the big wheel and pushed the pedals with his feet. "Penny Farthings" went much faster than "running machines" because of the big wheel, but were uncomfortable, too. The wheels were usually iron or wood. They were also dangerous because it was a long way to fall to the ground!
    In about 1876 a new kind of bicycle was born. People called it a "safety bicycle" because it was safer than a "Penny Farthing". The wheels were the same size and the rider did not have far to fall. It looked like bicycles we have today. The rider sat on the seat and pushed the pedals with his feet. This made the wheel at the back go round. "Safety bicycles" went very fast but they were not very comfortable. The wheels had hard rubber tyres.
    Then, in 1887, someone thought of making a new kind of tyre. It was rubber with air inside and was soft. A bicycle with tyres like this was safe and very comfortable to ride. Today all bicycles are like this.
