Biclycle - a Life Saver?
A bicycle is a human power-driven 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 cars 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 actions and for the purpose of fitness and even in the case of law enforcement actions such as petrolling an area.
The Story of Bicycles
Ever since the chain driven model was presented to the market, the basic
design of the bicycle had remained unchanged up to day. Nonetheless, the usage of modern material and innovation methods
such as computer-aided pattern has improved the many views of the bicycle. Some bicycles are especially
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 autos 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 pilot successfully the body of the rider must balance out the dynamics,
particularly 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.
Bicycle can be classified as an exceedingly
cost-effective 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
operating self powered method of transportation. Nearly, 99% of the energy is transmitted to the wheels of the bicycle when a
rider exerts energy into the pedals. However 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. 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 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. By using gears, the efficiency of the bicycle can be increased by descreasing effort and increasing output.
