Figure 1: Friedrich’s design for the bicycle included a steering device, allowing cyclists to control their direction. Despite these flaws, this simple bicycle caught on quickly over the next 26 years, as people made it look stylish by carving designs and staining or painting the wood. It had no steering mechanism or brakes– in order to make it move, the rider had to push it along with his feet. Except for various nuts and bolts, the entire device was made of wood. The two forks were connected to a bar, which had a seat fastened to it. This invention consisted of two similar-sized wheels, each attached to a fork. His bicycle was called a cheval de bois, or “wooden horse” in French. The first bicycle was fashioned in 1791 by the Count de Sivrac of France. Moreover, they might be hazardous for those on or near the bicycle, and completely obsolete next to other motor-run vehicles. Without these major building blocks, bikes would be unfit for use.

Engineers have developed several elements, without which today’s bicycles could not operate as they do, such as steering mechanisms, pedaling systems with gears and a chain, brakes, and pneumatic tires. Over the last two centuries, bicycles have evolved at a rapid pace, from the original, simple wooden contraption of the past to the high-tech, ergonomic machines of today. Introductionīicycles have existed for over two hundred years, and most of us have ridden one at some point during their lifetime. By analyzing the technology involved in its creation, modification, and evolution, one may obtain a better understanding of the tremendous role engineering plays in this everyday apparatus. Since the appearance of the first bicycle in the late 1700s, this machine has evolved from a simple wooden contraption with two wheels and a seat to a complex, metallic-alloy vehicle made of numerous components. Many disciplines of science and engineering are necessary in making the bicycle what it is today and will be in the future. Bicycles have been around for many years and are constantly being researched and improved.
