Introduction Modern bikes, like racing ormountain that are representedhere, evolved from its
predecessors in the seventeenth,
eighteenth and nineteenth
centuries. The invention of draisine
in 1817, with the handlebarforward, was a major improvement
over previous designs.
The pedal driven bicycle appeared
in the 1860s and in the 1890s were
built bicycles with wheels and tires
back and front of equal size, a
central dish connected to the
wheels via a chain, inflatable
wheels and brakes .

Evolution
In a section of the play "Codez
Atlanticus" of Leonardo da Vinci
and featured a drawing of a
bicycle. Leonard and thought of achain transmission as those used
at present.
These drawings were dispersed
by time and were collected
haphazardly in the Ambrosiana
Library in Milan.

The start
300 years later the Count Mede of
Sivrac materialized an
invention much more
rudimentary than Leonardo for
amusement of the nobility in
the streets of Paris.
The device that was constructed in
1790 with two wooden wheels
aligned, mounted on the ends
of a beam of a meter long, no
handlebars that allow setting
the direction, and no pedals.

The Walking Machine
In 1817 Baron von Drais invented a walking machine. The devicewas propelled by pushing your feet against the ground. The
machine became known as the Draisienne or hobby horse. It was
made entirely of wood. This enjoyed a short lived popularity as a
fad, not being practical for transportation in any other place than a
well maintained pathway.

Imagination
The inventors unleash your imagination.
It changes the iron timber to give the
bike more consistency and safety.

Pedaling Driving levers are added (Basic
handlebars).
Appear pedals on the front wheel to
make the drive mechanism.
The machine was driven by the push of
the feet downward and forward,
without touching the ground.
The front wheel was higher than the
back to comfortably reach the foot
pedal.
The pedals on the front wheel were
very difficult to balance while pedaling.
Materiality: The frame and wheels were
wooden, and the tires were of iron.

The balance
Believing troubleshoot balance and
speed, manufacturers increased the
diameter of the front wheels drive
wheels build reaching 3 meters in
diameter.
All this at the expense of safety, balance
and weight.
Some models came to weigh 40 kg.

The velocity
The excessive vibration and instability ofthe high-wheel bicycle, forced inventors
to strive to reduce the height of thebike.
Now the wheels were about the samesize.
It also reduces weight now fluctuatesbetween 18 and 20 kg.
Appear pedals attached to a sprocketand gear Through a chain of
transmission, moving behind the wheelto drive the machine.
Alternatively Pressing each of thepedals causes rotation of a ring gear,which meshes with a chain whichrotates the pinion of the rear wheel
On May 31, 1889 was officially competitive cycling, and since then the rate
became an obsession.

The race
In the 20's invented the shift as a result
of that cyclists had to face (in
competition or for entertainment) at
enormous distances by road dust, mud
and snow.
In the decades of 1970 and 1980 are 10-
speed bikes with hand brakes and
narrow high pressure tires.
Is implemented to accommodate the
height adjustment of the seat.
The handlebar is lower to achieve a
more aerodynamic body position and
thus achieve greater speed.
The materials are replaced to reduce
weight, experimenting with metal
alloys.

All Terrain
Later, road bikes, with tires tread depthand a stronger box, caused a furor.
No matter if both high speeds wouldnot compete in a race.
Here the bicycle speed change
inspiration for the pleasure, the bike isused in large part to walk.
The wheel is widened for greatersecurity, to horseback hills, fields, beachand city.
The system keeps changes to suit theenvironment.
The handle is easier and a bit higher
than the bicycle speed, as not that whatyou are looking for, but comfort,relaxation, sport.

The present bike
A bicycle today is a two-wheeled tricycle equal,which is the subsequent driving.
The bicycle consists of a rigid frame formed bytubes of steel, light alloys or high-strengthcomposite materials, which supports all parts ofthe machine.
At its rear the frame carries a fork holding the frontwheel axis and which is integral with the direction,in the rear fork ends of which has another encirclethe axis of the rear wheel, at the bottom are thepedals, and the angle opposite the seat.
The pedals are the main body of the transmissionof the movement of the rear axle. The front wheelis only guideline.
Being limited in absolute value the effort exertedon the pedals, you have to have severalcombinations to overcome resistance due tovarious road profile. For this reason is mounted agear change. The wheels comprise a rim attachedto the hub by spokes are shod with metal and tires(or if it is tubular racing bicycle).

Basic Information
The Segway is a very useful invention. It is basically a two-
wheeled scooter. It goes forward when you lean forward; the fartheryou lean that faster you go. To go backward you lean backward; thefarther you lean backward the faster you go. To turn, there is a handleon the handlebars you turn. If you turn it counterclockwise you turnleft, if you turn it clockwise you turn right. It can go 12.5 mph for adistance of 17 miles on a single charge. It weight about 80 pounds, andit can support up to 250 pounds. It uses gyroscopes to stabilize andkeep you upright.

Interesting Facts
There are many interesting facts about the Segway aswell. It can go over rough terrain easily without the user fallingoff. It can go 6.6x further than walking in 20min. There is acargo system to put on it in order to carry more things. Thereare also all sorts of accessories from bags and storage to lights
and traffic signals. Its also comes in a verity of colors andstyles depending on what you like. There are colors liketitanium color and midnight blue. There are also styals like theI style and the P style.

Inventor
In 2001, Dean Kamen invented this. He is
very smart in the subjects of physical science,
laws of physics, and modern technology. He has
over 150 U.S. and foreign patents. He founded
the group call F.I.R.S.T (For Inspiring and
Recognition of Science and Technology). This is
a group of high school teams who build robots
and then go to a competition.

Uses Today
Today it has many uses. It is popular in businesses.
Since it can carry items, it is very useful intransportation. Businesses it is used to carry items fromone place to another. Personal use is common as well.
People can use it to go from store to store, or they cango anywhere they want to. It is also just fun to ridearound.
