Lance Armstrong is a modern day sports hero, some say he ranks up with Jesse Owens and even surpasses that legend. Others compare him to the Soccer Legend Pele or the Hockey Great; Wayne Gretsky. Some say he and Tiger Woods are cut from the same mold. Few would disagree that he may well be the greatest Athlete in the World in our present period. If you admire Lance Armstrong and his accomplishments in cycling, you are not alone and you are correct in doing so.

Yet if you look at Lance’s achievements on the bicycle and his present efforts to cure cancer for all people of the world, well you might say that the Sports Hero we know, is a foreshadowing of things to come with his foundation and his fight to find a cure for cancer.

If you study winners and losers what you often find is that some winners can transfer that winning streak into other non-related endeavors. And one would bet that with the drive that Lance Armstrong has, that he may just be the motivating force to find a cure for cancer.

We as a nation and as citizens need to get behind his vision for the greater good and continue to push our leadership, scientists and society to work relentlessly to find a cure for all types of Cancer and we need to get behind the winning spirit of Lance Armstrong. Think on this.

Being one of the most basic human powered vehicles, the bicycle has two wheels affiliated to a vehicle that
is driven by a pedal. introduced during the 19th centuries bicycles are known to outdo the
total number of motor vehicles by a ratio of 2 to 1. In many regions of the globe, bicycles are the main method of carry. Although
the essential 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.

Bicycles and Its Story

Ever since the chain driven model was presented to the market, the primary
design of the bicycle had remained unchanged up to day. Nonetheless, the usage of modern material and design 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. 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.

Features of 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 attains this by moving forward
using the steering which allows some balance to the rider. In addition in order to successfully pilot 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 exceedingly
economic machine. Energy needed from the rider for the bicycle to perform 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 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. 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 mechanisms, seating, drivetrain, suspension, wheels and brakes. Certain bicycles may include optional
mechanisms such as gearing which uses different 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.
