I read on this book yesterday -The Race Across America, written by Geronimo Stilton. It is about his friend Bruce Hyena. He signed up the race for Geronimo Stilton.The race is about bicycles.
Here are some information on Bicycles:
The History of the Bicycle
The first bicycle was invented in 1861 by the French mechanic Ernest Michaux. It was called the velocipede. The velocipede had pedals mounted on a large font wheel. This helped riders travel very fast with little effort.
The modern bicycle was born in 1880 with the invention of the chain, which transfers power from the bicycle's pedals to its wheels. A few years later, rubber tires were added. Tires made riding a bike a lot more comfortable. Before they were invented, cyclists rode on wheels made of wood and iron.
Today racing bicycles have narrow tires, curved handlebars, and most important,a gear mechanism that makes it easier to pedal up even the steepest hills. These bikes are made from ultralight materials, like carbon fiber or titanium. Every piece of the bicycle is designed to be as light as possible to help to improve the rider's speed.
