Being one of the most basic human powered vehicles, the bicycle has two wheels tied to a vehicle that
is driven by a pedal. Bicycles were first presented in the 19th century and it is asked that presently there are approximately about
one billion bicycles worldwide, outnumbering cars 2 to 1. Bicycles being the main method of transport in many corners of the world, the bicycle is also majorly used for other recreational actions 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 fundamental
pattern of the bicycle had remained unchanged up to day. However, the usage of modern material and innovation methods
such as computer-aided innovation has improved the many views of the bicycle. Some bicycles are especially
constructed to adhee to standards of racing, cyclicling on mountains and even for law enforcement. In addition, many of the parts that played a
major role in the development of automobiles 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 referred to first. Bicycle needs its centre of gravity in order to be in its space. So it achieves this by moving forward
using the steering which offers some balance to the rider. Additionally, in order to pilot successfully the body of the rider must balance out the dynamics,
especially at turns. A technique mentioned to as counter-steering is used to attain this task by directly turning the handlebars with the hands
or indirectly leaning or slanting the bicycle.
Through both biological and mechanical view points, the bicycle is an super
streamlined machine. Energy needed from the rider for the bicycle to execute its
marvels are high on the list but given the distance that a bicycle can take you through without fuel, it becomes a
notable journey at the end. Nearly, 99% of the energy is transferred to the wheels of the bicycle when a
rider exerts energy into the pedals. However when gears mechanics are used this figure may drop by 10-15%.A rider using a bicycle
feels air drag or the resistive force that is exerted by air. 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 parts of the bicycle include the frame, steering mechanisms, seating, drivetrain, suspension, wheels and brakes. Some
bicycles use optional mechanisms to get advantage for the dynamics of the bicycle. By using gears, the efficiency of the bicycle can be increased by descreasing effort and increasing output.
