The Bicycle - a Life Long Partner
A bicycle is a human supercharged vehicle that has a frame tied with two wheels and that is
driven by a pedal. presented during the 19th centuries bicycles are known to outdo the
total number of motor vehicles by a ratio of 2 to 1. In many parts of the earth, bicycles are the main method of transport. Although
the primary use of the bicycle is as a means of transport, it has developed other uses including recreational actions, fitness activities
law enforcement diligences and competitive sports.
History of Bicycles
Ever since the chain driven model was introduced 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
constructed to adhee to standards of racing, cyclicling on mountains and even for law enforcement. Additionally, the concept of the bicycle has up to a great extent extended its contribution for the development of machines by introducing concepts such as ball bearings, pneumatic tires and spoke tensioned wheels.
What to Look for In a Bicycle
When relating to bicycles, the dynamics of the bicycle should be viewed first. A bicycle has to maintain its center of gravity over the wheels in order to stay upright or balanced.
Therefore, it reaches this by the moving forward using the steering which is unremarkably provided by the rider
and sometimes even by the bicycle itself. Additionally, in order to navigate successfully the body of the rider must balance out the dynamics,
especially at turns. Counter-steering is a task that is used in this regard.
Bicycle can be classified as an highly
efficient machine looked at in both biological and mechanical view point. When
comparing 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. The bicycle wheels carry nearly 99% of the energy because the rider exerts energy to pedals. But in
bicycles that have gear mechanisms, the energy needed will be diminished However the air drag faced by the rider will
always remain a problem. At higher speeds, importantly 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
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 distinct 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.
