Technology of Composite Bicycle Frames The definition of technology is systematic treatment/application of knowledge to produce something (Webster’s1496). I will take this definition and describe the technology of making a bicycle frame. Composites structures are defined as : “...constructions utilizing admixture or blend or a compound of distinct parts or elements of various available materials to produce a resulting structure of the highest possible strength to weight ratio ...” (Moynihan )
Introduction This task is a case study on the material choice of bicycle frame. The primary component of the bicycle is frame, which helps the bicycle to work as a complete efficient device. Bicycle frame have gone from wood to metal materials for innovative composites in the last and a half century. Bicycles themselves have gone from simple curiosities to serious ways of transport in developing nations and a significant form of sport and entertainment in western world. While the automobile and aerospace
information on the subject of mountain bikes and the advances in technology that the bike has gone through, and what might be in the future of the mountain bike. The road bike has taken more than a hundred years to evolve into the frame that it is being used on todays bicycle. Because of the increasingly popularity of the mountain bike the demand for advances to be made have come very rapidly. The evolution of the mountain bike has been a stormy one over the past decade. Within one decade the design
will discuss some of the physics involved in bicycles. Specifically, mountain bikes with suspension. A bicycle is a very energy efficient vehicle. Its wheels allow its rider to make full use of inertia and gravitational potential energy. The basic design of a bicycle has been around for over 100 years and compared to other things, has changed very little. Some of the topics that will be covered are: frames, wheels, suspension forks, suspension frames, brakes and how all these things affect speed
The bicycle, a two wheeled object that has gone through many renditions, has evolved into different kinds of new creations along the course of its history. Leonardo Da Vinci, created the blueprints and with the help of his students, tested and created the primitive form of a bicycle. Baron Karl Von Drais to Ignaz Schwinn help contribute to create a more modern version of transportation. During the 1400s many creators tried to look for an easier way of transportation.

The invention of the bicycle date far back to the 17th century, and since then has been constantly modified during the past decades to reach the bicycle who know today. The first bicycle , a wooden scooter-like vehicle, named a “celerifere,” was invented by Comte Mede de Sivrac of France. It consisted of
time-trial. Following the road bike is the “Mountain bike” which is made for dirt trails and rocky terrain. After the mountain bike is the “Cyclocross bike” they are for off season training, for professional bike riders. The bike has a heavy duty frame,with fatter and knobby tires. One of the new creations in the bike industry is the “Hybrid bike”, this bike has an upright sitting positions that has comfort amenities such as having a wide, thick seat and simple gears.

The Bicycles Changed America The great changes in American society that came with the introduction bicycle in the late 19th century are often overshadowed by the influence of the automobile in the following decades.

In 1817, the bicycle was introduced. It was clumsy, heavy, and dangerous. Throughout the last two centuries, modifications have made the bicycle easier to ride with inventions such as brakes, softer tires, and better maneuverability. The development of the modern day bicycle has led to increased environmental awareness, increased women’s civil rights, and permanently altered the public’s views on mass transportation. The first bike was called the Draisienne that was invented by Baron Von Drais in
