Transcript of Innovations of the bicycle

Innovations of the Bicycle Walking Machine Velocipede First machine to be called a 'bicycle'

Made all of metal

Very expensive The High Wheel Original High Wheel High Wheel Tricycle High Wheel Safety Safety Bicycles Kid's Bikes Racing Bicycles BMX Bikes Mountain Bikes Created to get around royal gardens faster
Made all of wood
Not very practical Pedal on front wheel

All wood with metal tires

Extremely uncomfortable when rode on the cobblestone roads Extreme Sports If the bicycle was to hit a rock or bump, with such a high center of gravity, the rider would fall over head first Safer alternative to the original high wheel

More for ladies First bicycle to use new innovations from the automobile such as: Rack and pinion steering
The differential
Band brakes By reversing the order
of the tires, the tipping
over problem was fixed First bicycle to use this modern design
Used chain and sprocket
Same sized wheels Pnuematic-tired First air-filled tires
Resulted in a much smoother ride This made bicycling so popular that the League of American Wheelman was formed Designed to look like automobiles Extremely popular Sturdy frame
Large wheels
Flat handlebars Small & heavy duty frame
Pegs Dropped handlebars
Narrow tires
Different speeds
Light frame Boron von Drais - 1817 Denis Johnson - 1818 James Starley - 1870 John Dunlop - 1888 Harry James Lawson Will Laidler and Isaac Gaskin Millions of people across the world use bicycles everyday! Bicycles provide a source of exercise, competition, something fun to do, and much more. But bicycles have had the largest impact on transportation. For many people, they rely on bicycles to get around during their everyday lives, and with new modern bicycles, it’s becoming a much better experience. Impacts Engineering 2 disciplines most essential to the development of bicycles are mechanical and transportation engineering.

Mechanical engineering is essential to the development of bicycles because bicycles have a lot of moving parts, such as the chain and gears, and mechanical engineers help improve parts like these.

Transportation engineering also played a huge role in the development of bicycles. When bicycles were first invented, they weren’t very popular because there was no where to ride them. Then, around the 1880s when better roads were made, it was easier to ride bicycles around and they started gaining popularity. Given the opportunity to change something in the bicycle, we would change the way of shifting gears. Instead of having to hit a knob many times to change gears, one push of a button or touch screen would put it into the gear you want. A quick history of bicycles. (n.d.).
