Biclycle - a Life Saver?
Being one of the most basic human power-driven vehicles, the bicycle has two wheels connected to a vehicle that
is driven by a pedal. Bicycles were first introduced in the 19th century and it is asked that currently there are approximately about
one billion bicycles worldwide, outnumbering cars 2 to 1. In many parts of the world, bicycles are the main method of carry. Although
the essential use of the bicycle is as a means of carry, it has developed other uses including recreational activities, fitness activities
law enforcement diligences and competitive sports.
History of Bicycles
Since the origin of the chain-driven model in around 1885, the fundamental pattern and the shape of a
typical bicycle has remained relatively unchanged. But, other advances such as using computers to design
and check the stability have been made to the bicycle from its inventing process. Some bicycles are particularly
manufactured 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 cars for instance, ball bearings, pneumatic tires and spoke tensioned wheels were initially intended for
the bicycle.
Features of a Bicycle
Dynamics
of the bicycle is something that should be mentioned 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 provides some balance to the rider. Additionally, in order to pilot 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.
Bicycle can be classified as an super
streamlined machine looked at in both biological and mechanical view point. When
equating 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. Nearly, 99% of the energy is conducted to the wheels of the bicycle when a
rider exerts energy into the pedals. Nevertheless when gears mechanisms are used this figure may drop by 10-15%.A rider using a bicycle
experiences 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 practiced 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. 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, crescendo the efficiency of the bicycle.
