Bicycle, we all must have enjoyed  the pleasure of cycling during our childhood or teenage time, it will be totally correct if  bicycles said to be the first vehicle of our lives. The journey of owning different vehicles all begins with a bicycle. Now, here is the journey of Bicycle.
A bicycle is also called as cycle or bike, it is a human powered, pedal driven, single track vehicle having two wheels attached to frame one behind the other. Bicycle are the basic means of transport and it is highly popular among small children and tenagers.
They are also used for general fitness, and military and police applications and bicycle racing.



The bicycle’s invention has had a massive effect on society, in terms of modernity and culture. Several components  that were used in bicycle such as ball bearing, pneumatic tires, chain-driven sprockets and tension spoked wheels later they played a vital role in the development of the automobile and also advancing modern industrial methods.



The first human means of transport “Dandy horse”  having two wheels was invented by the German Baron karl von Drais. The structure was like rider sat astride a wooden frame supported by two  in line wheels and pushed the vehicle along with his or her feet while steering the front wheel.
In the early 1860, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical  crank drive with pedals on an enlarged front wheel. Later several inventions followed using rear wheel drive, but the best known being the rod -driven velocipede by the Scotsman McCall in 1869.
Further innovations increased comfort and ushered in a second bicycle craze, the 1890s Golden Age of Bicycles. The first practical  pneumatic tire  was introduced in the year 1888  by Scotsman In John Boyd Dunlop which soon became universal. Soon after, the rear freewheel was developed, enabling the rider to coast. This refinement led to the 1890s invention  of coaster brakes. The Svea Velocipede with vertical pedal arrangement and locking hubs was introduced in 1892 by the Swedish engineers Fredrik Ljungström And Birger Ljungström. It attracted attention at the World Fair and was produced in a few thousand units. Bicycles are the most common vehicle of any kind in the world, and the most numerous model of any kind of vehicle, whether human-powered or motor vehicle, is the Chinese Flying Pigeon, with numbers exceeding 500 million. The next most numerous vehicle, the Honda Super Cub motorcycle, has more than 60 million units made, while most produced car, the Toyota Corolla, has reached 35 million and counting.


Uses of Bicycle:

From the very first invention of the cycle till today, they have been used for many purposes. First of all bicycle are used as a basic means of transportation, can be used as a workhorse, used by mail carriers, paramedics, police, messengers, and general delivery services. Military uses of bicycles include communications, reconnaissance, troop movement, supply of provisions, and patrol. 

Nowadays., bicycle are used for recreational activities and entertainment purposes like bicycle touring, mountain biking, physical fitness, and play. Bicycle competition includes racing, BMX racing, track racing, criterium, roller racing, sportives and time trials,artistic cycling and freestyle BMX.


Parts of Bicycle: 

  • Frame.

  • Drivetrain and gearing.

  • Seating.

  • Brakes.

  • Suspension.

  • Wheels & amp; tires.


Types of Bicycle:

Bicycles can be categorized in many different ways: by function, by number of riders, by general construction, by gearing or by means of propulsion. 

The more common types include utility bicycles, mountain bicycles, racing bicycles, touring bicycles, hybrid bicycles, cruiser bicycles, and BMX bikes.

Less common are tandems, low riders, tall bikes, fixed gear, folding models, amphibious bicycles, cargo bikes, recumbents and electric bicycles.

Unicycles, tricycles and quadracycles are not strictly bicycles, as they have respectively one, three and four wheels, but are often referred to informally as "bikes" or "cycles".


Utility Bicycle:

These are the most commonly used bicycle globally designed for practical transportation. They are majorly used in developing countries.


Mountain Bicycle:

These are especially structured and designed for off-road trails or non pavement paths. These have flat or upright handlebars, and a very low gear range for pedaling up steep trails.


Racing Cycle:

This cycle is also known as road bike, it is designed for competitive road cycling a sport governed by according to the rules of the Union Cycliste Internationale.


Touring Bicycle:

These are special type of road-bikes which are designed for the paved roads. They have a good durability and self support mechanisms for the longer distance riding.


Hybrid Cycle:

These are both road and mountain types of bikes or bicycles, sometimes also referred as cross bikes. These have large padded seats and upright handlebars, which are known to provide a comfortable riding posture.


Cruiser Bikes:

These cycles are preferred for short distance commuting and errands, they are similar to hybrid bikes, which are designed for casual ridings. As like hybrid bikes, even they also provide straight and comfortable posture while riding.


BMX Bikes:

These are popular small sized bikes or bicycles, which are popular among kids. These are used for performing various styles of trick and stunt riding.



Mechanically and biologically bicycle is extraordinarily efficient , it is the most efficient human-powered means of transportation in terms of energy. Mechanically, up to 99% of the energy put by the rider into the pedals is transmitted to the wheels, although the use of gearing mechanisms may reduce this by 10–15%. In terms of the ratio of cargo weight a bicycle can carry to total weight, it is also an efficient means of cargo transportation.

A person traveling on a bicycle at low to medium speeds of around 16–24 km/h (10–15 mph)  only uses the power required to walk. Air drag, which is proportional to the square of speed, requires completely higher power outputs as speeds increase.   If the rider is sitting upright, the rider's body creates about 75% of the total drag of the bicycle/rider combination. Drag can be reduced by seating the rider in a more smooth streamlined position. Drag can also be reduced by covering the bicycle with an aerodynamic fairing. The fastest recorded unpaced speed on a flat surface is 144.18 km/h (89.59 mph)production and transportation of the food required by the bicyclist, per mile traveled, is less than 1/10 that generated by energy efficient motorcars.

Bicycles are the most eco-friendly vehicles ever, it not only saves fuel, not create any noise and air pollution along with that  they are easy to handle and cheaper in cost. Using it for travelling short distances, is not a bad idea as you can save your time from traffic jams and besides of that it has many health benefits. Taking a ride from bicycle you can contribute to the environment as well can maintain your good health.
