The history of Bicycles is very interesting. I go for morning walks. From time to time, i saw an old man riding different bicycles every other day. Out of curiosity, i googled the bicycle history. This is what i came up with. Hope this was infomative.

2.  Invented by by Baron von
Drais in 1817.
 Two same-size in-line wheels,
the front one steerable,
mounted in a frame which you
straddled.
 Made entirely of wood.
 Not practical for
transportation in any other
place than a well maintained
pathway such as in a park or
garden

3. Next appearance was in 1865 with
pedals attached in the front.
Since it was made by wood with metal
tires, and the combination of these with
the cobblestone roads of the day made
for an extremely uncomfortable ride.
Indoor riding academies, similar to roller
rinks, could be found in large cities.Boneshaker

4.  In 1870 the first all metal
machine appeared.
 Solid rubber tires and the
long spokes of the large front
wheel provided a much
smoother ride than its
predecessor.
 The front wheels became
larger as makers realized
that larger the wheel, the
farther you could travel with
one rotation of the pedals.
The High Wheel

5.  They cost an average worker
six month's pay.
 Because the rider sat so high
above the center of gravity, if
the front wheel was stopped,
the rider, with his legs
trapped under the
handlebars, was dropped
unceremoniously on his
head.

6.  First machines to be called as

8.  Ladies, confined to their long
skirts and corsets, took a
spin round the park on the

 Rack and pinion steering, the
differential, and band
brakes, were invented for
this bicycle.

9.  Improvements began to be
seen.
 Small wheel in front
introduced to eliminate
tipping-forward problem.
 These bicycles came to be
known as ‘Ordinary Bicycles’
or just ‘Ordinaries’
High Wheel Safety

10.  With improvement in
metallurgy, the design
returned to the previous one.
 Instead of just one wheel
circumference for every pedal
turn, you could, through the
gear ratios, have a speed the
same as the huge high-wheel.
 These designs competed with
each other, your choice: the
high-wheel's comfort or the
safety's safety.
Hard Tired Safety

11.  Pneumatic tire first applied
by Irish veterinarian for his
son’s comfort.
 Practical investment for the
working man as
transportation.
 Ladies could ride now with
their legs covered by skirts
and corsets on.

13.  Mountain bike was usedfor
freewheeling down
mountain trails.
 The sport became popular in
the late 1970s.
 Titanium carbon fibre frames
were popular but became
very expesive.
