The Bicycle A Healthier and Environmentally Friendly Alternative to the Gas Engine A bicycle is a transportation device that is human powered and has two wheels. There are five main components that make up a bicycle: the frame, front set, brakes, chain system, and wheels. As all of you know global climate change and obesity are upon us. Over half of the country struggles with their weight and the climate is becoming more and more unpredictable every day. Solutions to these problems, such as weight loss pills and electric cars, have been thought of as solutions, but we have been sitting on a better solution for over a century now, the bicycle. The bicycle can be used for both transportation and leisure. More and more people are turning to bicycles. Not only will they save you money on gas and the repair prices associated with a car, but you will burn thousands of calories traveling on your bike rather than passively sitting in your car. Bicycles are cheap and have low environmental impact, no wonder there are over a billion worldwide. The Frame: The frame is the largest and most central part of the bicycle, the backbone that holds the entire machine together. It is made out of several aluminum bars that are welded together. A lightweight or a sturdier frame can be purchased depending on the intended use of the bicycle. There are several different styles of frames including: the diamond, step-through, and cantilever, the You may want a sturdy or lightweight frame depending on your intended use. A lightweight is used for racing or a heavier frame for off-road riding. last being the most popular. As seen in Diagram 1. The frame consists of five parts: the top tube, seat tube, down tube, seat stay and chain stay. The seat stay is used for holding the seat in place. The top tube connects the front set to the seat set, whereas the down tube connects the chain system (the power system of the bike, located on the rear wheel) to the front set.

The Front Set: The front set consists of three different parts: the front wheel, head tube, and handle bars. The handle bars provide the rider with the ability to turn and control the bike. A simple push or pull will cause the front wheel to turn in the desired direction. The handle bars are connected to the front wheel via the head tube (The bar that connects the handle bars to the front wheel). When beginning a change of direction it is important to begin slowly and Always make sure before riding that your front set is well lubricated you want to be able to turn when you need to! maintain balance otherwise a crash is inevitable. The Chain System: The chain system is takes the energy provided by the rider pushing on the pedals and transfers that energy to make the rider go forward. The rider places his or her feet on the pedals causing the crank attached to turn the gears. This forces the drive chain to rotate the back wheel. To change gears, the rider turns a knob on the steering wheel, which causes the chain to go onto a smaller or larger gear depending on what the rider wants. Changing gears can make a rider go faster or make traveling up a hill easier depending on the situation. A simple twist of the wrist will cause you to change gears. Low gears are used for challenging hills and high gears for speed. The Wheels: The wheels contain three parts: a hub, spokes, metal rim, and a rubber tire. Most of your weight is supported by the wheels. Bike wheels use spokes wheels instead of metal wheels like cars have. The reason behind this is because bikes do not have to support that much weight and have to remain lightweight themselves. The reason a tire is rubber is because the rubber inflicts friction on the road, providing grip and helping the bike stay upright. A wider tire will provide you with more friction, therefore more stability. However, with the added stability you are increasing wind resistance, which will lead you to lower maximum If you’re looking to go fast on well paved roads, opt for the thin tires, as you won’t need the extra friction. If you plan on taking your riding through the woods, make sure to purchase thick tires. speeds. Bicycles provide several upsides and only a small downside. They are able to cause injury. Make sure to always wear a helmet while riding. Riding your bike for three hours or over 20 kilometers a week can cut your risk of heart disease in half. If you pay attention to the distance you travel in your car, most of the trips you make are less than 5 miles. These trips could all be easily made on bicycles! Parking your car can always provide an annoying issue when traveling. All you need to park your bike is a lock and a tree. You can fit over double digits of bikes in a parking space that can only fit one car. With all these benefits, how can you resist buying one today?
