Bicycles are ridden every where in the world, in some areas more than others. The purposes of the bicycles are very different as well. Since the beginning of the invention of bicycles, people have been able to go faster and travel longer with their own muscles. In a way, it is one of the more efficient machines. Looking at it thermodynamically, it may not be due to the amount of heat us humans dissipate. However if the system was to be just the bicycles, they are very efficient, especially the road bicycles in turning the muscle work in to the distance and speed at which the individual travel at.

Through this network of bicycles that have formed, people can commute from one place to another without too much impact on the environment. At least compared to cars, it is a lot more environmentally friendly. The down side to bicycles is that parking areas are not very attractive and there are some wastes that are created, such as scraps of metals from old bicycles. If more people are willing to travel by bikes to school or work, it would definitely provide a better atmosphere due to cut back in the emissions of carbon dioxide. This is because other transportations such as cars emit large quantities of carbon dioxide from combustion of petroleum product. The cars also emit carbon monoxide, un-reacted carbon macromolecules and soot. These emissions can be cut back and to provide a healthier environment for the future, bicycle is a great alternative transportation. At the same time, it provides great benefit for the rider’s health.

To implement this environmental friendly idea, it would help to for the various areas in the world to create safer environment for the bicycle riders. Such environment may be to create path just for bicycle riders so that they do not have to share a busy road with cars. Accidents do occur when people ride on the bicycle on busy streets. At the same time, although it may not be the most attractive things, more bicycle racks can be installed at main gathering areas such as the train stations. The lack of places to park bicycles discourages riders from riding their bikes.

As for mountain biking goes, it’s a great sport and more trails should be marked on the trail for them. Biking can act as great recreational sports. Biking in the outdoors can provide a great environment for those whom are stressed and need to be out from the busy cities.

The downhill and freeriding aspect of the biking community is increasing as well. Although these special durable bikes are very expensive at this point, over the last few years, the prices have been coming down. At the same time, they are starting to make cheaper parts at lower qualities. This encourages the younger population to buy these bikes, which would increase the popularity. I feel that at this point, it the pricing of the bikes that is the problem. The downhill bikes for instance cannot be purchased with less than $2000 dollars. For a good quality bike, it is about 5000 US dollars. As for some of the freeride bikes, you can get a decent one for about a thousand dollars. Although these are very expensive, I am sure the prices will keep on coming down with time.
