Being one of the most basic human supercharged 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
full number of motor vehicles by a ratio of 2 to 1. In many areas of the globe, 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 actions
law enforcement applications and competitive sports.
The Story of Bicycles
Since the inception of the chain-driven model in around 1885, the primary design and the shape of a
typical bicycle has remained relatively unchanged. However, the usage of modern material and design methods
such as computer-aided pattern has improved the many aspects of the bicycle. These methods have greatly aided the spawn of
specified bicycles for particular purposes such as racing, utility and law enforcement uses. 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.
Things to Look 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 achieves 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. Counter-steering is a task that is used in this regard.
Bicycle can be classified as an exceedingly
efficient machine looked at in both biological and mechanical view point. Energy needed from the rider for the bicycle to perform its
wonders are high on the list but given the distance that a bicycle can take you through without fuel, it becomes a
valuable journey at the end. Nearly, 99% of the energy is carried 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. Nonetheless, the exerted drag can be significantly
diminished by placing the rider in a supine or a prone position and by covering the bicycle with fairing that is aerodynamic.
The main parts of the bicycle include the frame, steering mechanisms, seating, drivetrain, suspension, wheels and brakes. Some
bicycles use optional mechanisms to get advantage for the dynamics of the bicycle. By using gears, the efficiency of the bicycle can be increased by descreasing effort and increasing output.
