A bicycle is a human powered vehicle that has a frame affiliated with two wheels and that is
driven by a pedal. Bicycles were first introduced in the 19th century and it is claimed that presently there are approximately about
one billion bicycles worldwide, outnumbering autos 2 to 1. Bicycles being the main method of carry in many corners of the earth, the bicycle is also majorly used for other recreational activities and for the purpose of fitness and even in the case of law enforcement actions such as petrolling an area.

Bicycles and Its Story

Ever since the chain driven model was presented to the market, the key
design of the bicycle had remained unchanged up to day. But, other advances such as using computers to design
and check the stability have been made to the bicycle from its inventing process. These methods have greatly aided the spawn of
particularized 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 cars for instance, ball bearings, pneumatic tires and spoke tensioned wheels were initially intended for
the bicycle.

What to Look for In a Bicycle

When relating to bicycles, the dynamics of the bicycle should be considered first. Bicycle needs its centre of gravity in order to be in its space. So it attains this by moving forward
using the steering which allows some balance to the rider. Additionally, in order to pilot successfully the body of the rider must balance out the dynamics,
especially at turns. Counter-steering is a task that is used in this regard.

Bicycle can be classified as an highly
economical machine looked at in both biological and mechanical view point. When
comparing the energy an individual must spend to travel a given distance, the bicycle is stated to be the most efficiently
functioning self supercharged method of transportation. 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 decreased Nonetheless the air drag faced by the rider will
always remain a problem. When the speed is high, a lot of energy will be needed
to overcome this airdrag resulting in an exhaustive ride for the rider. The only way to reduce the air drag is to significantly reduce the position to supine or prone that is in line with aerodynamics.

The main parts of the bicycle include the frame, steering mechanics, seating, drivetrain, suspension, wheels and brakes. Some
bicycles use optional mechanisms to get advantage for the dynamics of the bicycle. Using gears a rider can produce a higher power output with a relatively low
power input and thus, maximising the efficiency of the bicycle.
