The Invention of the first bicycle

- Invented in 1817, by Karl von Drais, in Germany- it was called a running machine or Draisine- was patented in 1818- was made of wood, leather and a steerable front wheel- you had to push the wheel with your legs - 1818-1820 it became a must have

Draisine

Pedels and crank on a bike

- developed by Pierre Michaux in the 1860s- it had pedals and a rotating crank on the front wheel- quickly became a hit- was very heavy because of the metal frame and therefore clumsy- it could weight up to 50 kilos- front wheel was slightly larger than the back wheel

Pedels androtating cranks

The Evolution of the high wheel

- larger front wheel higher speed- rear wheel was more a support wheel - as long as increased to today's high wheel- in Great Britan known as " Penny-Farthing" - getting on was difficult

The High Wheel

Safety Bike

- further development of the high wheel- named after a safe variant of the high wheel - had a gear shift, chain drive, handlebars and a front wheel fork - John Kemp Starley's Rover became the prototype of the modern bicycle - the epoch of the " Cult of the bicycle"- had a effect on women in the society - women could not ride well with their heavy dresses or corsets evolution of gender-neutral clothing

Safety Bike

first races with bikes

- around 1890 first races with the bicycle development to the racing bike- 1947 first bicycle race after 1939- Germany and Italy were excluded - Tour consists out of 20-25 stages ( through France, Luxembourg and Belgium)- the rider with the shortest time to finish won the single stage- this point system lasted until the 1980s

first races with bikes

The mountainbike is created

- after many small changes, in 1981 there was a major development and this is how the Mountainbike was invented - Joe Breeze, Charles Kelly and Gary Fisher are considered Inventors- they were looking for new trails to ride down on their bikes- tinkered with their bikes to make them more ajustable- improved the shocks and put wider tires on their bikes - the idea had quickly expended and mountain biking became a sport

The Mountain bike

Environment and bike sharing

- Nowdays cycling is supported a lot- more and more people nowdays use the bicycle as a cheap and environmentally friendly means of transport- In Europe and the USA it is now possible to rent bicyclesand return them at market places - In 1995 the e-bike was invented which is a good alternative for those who are not that sporty
