Being one of the most basic human power-driven vehicles, the bicycle has two wheels tied to a vehicle 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. 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.
History of Bicycles
Since the inception of the chain-driven model in around 1885, the basic design and the shape of a
typical bicycle has remained relatively unchanged. But, other advances such as using computers to innovation
and check the stability have been made to the bicycle from its inventing process. Some bicycles are especially
factory-made 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 autos 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 thought first. A bicycle has to maintain its center of gravity over the wheels in order to stay upright or balanced.
Therefore, it achieves this by the moving forward using the steering which is usually provided by the rider
and sometimes even by the bicycle itself. In addition in order to successfully pilot a turn, the combined or total 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 super
competent 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
precious 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 mechanics, the energy needed will be diminished 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. Nevertheless, the exerted drag can be significantly
reduced 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 mechanics, 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.
