Biclycle - a Life Saver?
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 introduced in the 19th century and it is claimed that currently there are approximately about
one billion bicycles worldwide, outnumbering motorcars 2 to 1. Bicycles being the main method of transport 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
innovation 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 manufacturing process. Some bicycles are particularly
invented 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 motorcars for instance, ball bearings, pneumatic tires and spoke tensioned wheels were initially intended for
the bicycle.
What to Look for In 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 reaches this by moving forward
using the steering which provides some balance to the rider. 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.
Bicycle can be classified as an highly
economic machine looked at in both biological and mechanical view point. Energy needed from the rider for the bicycle to perform its
questions are high on the list but given the distance that a bicycle can take you through without fuel, it becomes a
worthwhile 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 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
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 peculiar 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, crescendo the efficiency of the bicycle.
