The Bicycle – a Life Long Partner
Wednesday, November 11th, 2009A bicycle is a human power-driven 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
full number of motor vehicles by a ratio of 2 to 1. Bicycles being the main method of carry in many corners of the globe, the bicycle is also majorly used for other recreational activities and for the purpose of fitness and even in the case of law enforcement actions such as petrolling an area.
The Story of Bicycles
Since the origin of the chain-driven model in around 1885, the key pattern and the shape of a
typical bicycle has remained relatively unchanged. However, 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
specialized 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 automobiles 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 reaches this by moving forward
using the steering which offers some balance to the rider. Additionally, in order to pilot 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.
Through both biological and mechanical view points, the bicycle is an highly
cost-effective machine. Energy needed from the rider for the bicycle to execute its
marvels 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. 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 reduced Nonetheless the air drag faced by the rider will
always remain a problem. 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
mechanics such as gearing which uses distinct sizes of gears to obtain a mechanical advantage from the bicycle. Using gears a rider can produce a higher power output with a relatively low
power input and thus, increasing the efficiency of the bicycle.
