Being one of the most basic human supercharged vehicles, the bicycle has two wheels affiliated to a vehicle that
is driven by a pedal. introduced during the 19th centuries bicycles are known to outdo the
full number of motor vehicles by a ratio of 2 to 1. Bicycles being the main method of carry in many corners of the world, the bicycle is also majorly used for other recreational activities and for the purpose of fitness and even in the case of law enforcement activities such as petrolling an area.

The Story of Bicycles

Ever since the chain driven model was presented to the market, the key
pattern of the bicycle had remained unchanged up to day. But, other advances such as using computers to pattern
and check the stability have been made to the bicycle from its inventing process. These methods have greatly aided the spawn of
special bicycles for particular purposes such as racing, utility and law enforcement uses. In addition, many of the parts that played a
major role in the development of machines for instance, ball bearings, pneumatic tires and spoke tensioned wheels were initially intended for
the bicycle.

Things to Look in a Bicycle

Dynamics
of the bicycle is something that should be mentioned to first. A bicycle has to maintain its center of gravity over the wheels in order to stay upright or balanced.
Therefore, it accomplishes this by the moving forward using the steering which is usually provided by the rider
and sometimes even by the bicycle itself. Additionally, in order to navigate successfully the body of the rider must balance out the dynamics,
particularly at turns. Counter-steering is a task that is used in this regard.

Through both biological and mechanical view points, the bicycle is an extremely
competent machine. Energy needed from the rider for the bicycle to execute its
wonders are high on the list but given the distance that a bicycle can take you through without fuel, it becomes a
precious journey at the end. The bicycle wheels carry nearly 99% of the energy because the rider exerts energy to pedals. But in
bicycles that have gear mechanics, the energy needed will be reduced Nonetheless the air drag faced by the rider will
always remain a problem. At higher speeds, significantly greater power outputs are needed to overcome the air drag. When a rider is sitting in an upright position, the
body of the rider accounts for nearly 75% of the full drag experienced by the bicycle and rider combined. The only way to reduce the air drag is to importantly reduce the position to supine or prone that is in line with aerodynamics.

The main
features of a bicycle are frame, steering mechanics, seating, drivetrain, suspension, wheels and brakes. Certain bicycles may include optional
mechanisms such as gearing which uses various sizes of gears to obtain a mechanical advantage from the bicycle. Using gears a rider can produce a higher power output with a relatively low
power input and thus, maximizing the efficiency of the bicycle.
