Biclycle – a Life Saver?
Being one of the most basic human power-driven vehicles, the bicycle has two wheels connected to a vehicle 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 activities and for the purpose of fitness and even in the case of law enforcement activities such as petrolling an area.
The Story of Bicycles
Since the inception of the chain-driven model in around 1885, the primary pattern and the shape of a
typical bicycle has remained relatively unchanged. Nonetheless, the usage of modern material and innovation methods
such as computer-aided pattern has improved the many views of the bicycle. These methods have greatly aided the spawn of
particularized bicycles for particular purposes such as racing, utility and law enforcement uses. Additionally, the concept of the bicycle has up to a great extent extended its contribution for the development of cars by introducing concepts such as ball bearings, pneumatic tires and spoke tensioned wheels.
Things to Look in a Bicycle
Dynamics
of the bicycle is something that should be referred to first. Bicycle needs its centre of gravity in order to be in its space. So it attains this by moving forward
using the steering which offers 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.
Through both biological and mechanical view points, the bicycle is an super
competent machine. When
comparison the energy an individual must spend to travel a given distance, the bicycle is stated to be the most efficiently
operating self supercharged method of transportation. Nearly, 99% of the energy is carried to the wheels of the bicycle when a
rider exerts energy into the pedals. Nevertheless when gears mechanisms 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. 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 total drag experienced by the bicycle and rider combined. 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 mechanisms, seating, drivetrain, suspension, wheels and brakes. Some
bicycles use optional mechanics to get advantage for the dynamics of the bicycle. Using gears a rider can produce a higher power output with a relatively low
power input and thus, maximizing the efficiency of the bicycle.
