The Bicycle
The bicycle, or bike, needs no fuel
to run, is easy to ride, and does not need a lot of care to keep
it running.
The bike has been around for about 100 years. It
has a diamond- shaped frame and two wheels of equal size.
The rear wheel through a chain drives it.
To make it easier to climb hills, many bikes have
gears.
The first bike was built in 1818.
The front wheel was used for steering. It moved by pushing
on the ground with the feet. In the late 1830s, a man built a
bicycle called a velocipede which was moved along by pedals and
cranks. In 1870, the first ordinary bicycle was built.
It had a huge front wheel. In the year 1886, the
diamond-shaped frame, chain drive, and wheels of equal size bike
was developed.
