Do you know when the first bike appeared It was in 1817. The early bikes were difficult to ride. They didn't have pedals (踏板). People had to move them forward by pushing their feet against the ground.
In 1839, a Scottish man, Kirkpatrick Macmillan, invented a new kind of bike. It had pedals. With the help of the pedals, people could ride the bike much faster. But the wheels were made of wood, so they were easy to break.
Later, in 1885, J. K. Starley from England made important changes to the bike. He made the front wheel smaller than the back one. He also made the wheels out of rubber. These changes made the bike lighter and easier to ride. Since then, the shape of the bike has not changed very much.

Thomas Edison began to work on the light bulb in 1878. He tried thousands of materials to find the right one to make a filament (灯丝) for the light bulb. After more than 1,000 experiments, he finally found a good material in 1879. The first light bulb could burn for about 13 hours.
