A bike, also known as a two-wheeler or pedal-cycle, is a pedal-driven or human powered, single wheeled vehicle, with two independent wheels attached either to a fixed frame or to a rack that may be secured to a fixed structure, on a public path. A biker is commonly called a cyclist, or biker. A road biker, on the other hand, stands in a position that demonstrates his ability to use his arms for both riding and walking. Bicyclists are usually thought of as being fashion conscious and those who ride bicycles with fashion sense, often have a tattoo of some sort of bicycle symbol displayed somewhere on their arm, perhaps to emulate the look of the bicycles that they see while out and about. However, many cyclists do not actually sport any symbols on their arms; rather, they typically just wear bicycle helmets.
A bicycle is classified by the manufacturer according to the type of drivetrain it uses, i.e. whether the bicycle has a rear or front engine. Most bicycles have a front wheel drivetrain, which is facilitated by a chain and sprocket attached directly to the back wheel on the bicycle’s left side, with the handlebar having a lever attached to the levers on the right side of the frame. The engine of the bicycle is usually placed below the handlebar in a compacted casing, much like a vehicle’s engine.
A typical bicycle frame has a number of different components that allow it to be built up and then disassembled when needed. One of these components is the seat tube, which defines the distance from the center of the seat tube to the top of the handlebar. The other component of a bicycle frame is the top bracket, which connects the seat tube to the seat. The remaining parts of the frame, such as the crank and chains, are detachable and are built separately. Some bikes have additional features such as hand bars and a shock lock. However, most bikes feature the basic set of bike parts, with the frame being the defining part of the bike.
The first bicycle frames that were made from steel were not very durable, as they were not designed for long time use, and were typically used only for racing on flat terrain. The need for a durable frame prompted cyclists to look at other materials such as aluminum, which is stronger than steel but lighter, making it ideal for use on smooth road surfaces. Aluminum road bikes were developed by adding a layer of thin carbon fiber to the frame of a road bike to reduce weight and increase durability.
The popularity of mountain bikes quickly increased after it was discovered that the frame of these bikes was similar to that of a mountain bicycle. With the popularity of the mountain bike, came the need for sturdy, rugged mountain bikes that could be used for off road travel, and the development of specialized mountain bike categories such as the all mountain, trail, hybrid, free ride, sport bike, and dual suspension. Bicycles with special handlebars for comfort and control were created as well. Bicycles with sport bike handlebars and sport bike pedals were designed to provide maximum comfort and control while the rider is riding. Bicycles with upright handlebars are also designed for maximum control.
All bike tires are made to work together as one unit to provide a smooth ride and provide traction in all types of weather conditions. Most bicycle frames are constructed with a deck, which holds the bike frame and all of the bike parts together. The deck is then covered with a variety of different types of materials, such as aluminum, wood, and plastic, to customize the frame’s look and make it more attractive to the general public. Many people prefer to choose bicycle tires that are designed for a certain type of terrain and road use.
