The Bicycle - a Life Long Partner
Being one of the most basic human powered vehicles, the bicycle has two wheels tied to a vehicle that
is driven by a pedal. introduced during the 19th centuries bicycles are known to outdo the
total number of motor vehicles by a ratio of 2 to 1. In many areas of the world, bicycles are the main method of transport. Although
the essential use of the bicycle is as a means of transport, it has developed other uses including recreational actions, fitness actions
law enforcement applications and competitive sports.
History of Bicycles
Since the inception of the chain-driven model in around 1885, the basic innovation and the shape of a
typical bicycle has remained relatively unchanged. Nevertheless, the usage of modern material and pattern methods
such as computer-aided design has improved the many views of the bicycle. Some bicycles are particularly
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.
What to Look for In a Bicycle
When mentioning to bicycles, the dynamics of the bicycle should be viewed first. Bicycle needs its centre of gravity in order to be in its space. So it accomplishes this by moving forward
using the steering which provides some balance to the rider. In addition in order to successfully navigate a turn, the combined or full center of mass
of both the bicycle and the rider must lean into the turn. A technique mentioned to as counter-steering is used to attain this task by directly turning the handlebars with the reaches
or indirectly leaning or slanting the bicycle.
Through both biological and mechanical view points, the bicycle is an super
cost-efficient machine. 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 expressed to the wheels of the bicycle when a
rider exerts energy into the pedals. Nonetheless 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. 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 parts of the bicycle include the frame, steering mechanisms, 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.
