Evolutions of Bicycle

  1. 1. A bicycle is a two wheeledvehicle that is moved withpedal, which are attached tothe wheels with a gear andchain. You steer the bicyclewith handlebars.
  2. 2. Pedaling History has on display even therecent history of the bicycle in Americathat we are more familiar with: the “English 3-speed “ of the 50’s through the70’s, the 10-speed derailleur bikes whichmore popular in 70’s( the derailleur hadbeen in more- or -less common use inEurope since), and of course the mountainbike of right now . There are also manyoddball designs that never quite made it ,including the Ingo.
  3. 3. The celerifere did not had any steering mechanism and no pedals. The users find it hard to use since it was the feet should be use to control entirely the machine.The celerifere was an early bicycle precursor invented in1790 by Frenchmen, Comte Mede de Sivrac. It had nosteering and no pedals but the celerifere did at least looksomewhat like a bicycle. A rider would power forward byusing their feet for a walking/running push-off and then glideon the celerifere.
  4. 4. In 1817 Baron von Drais invented a walking machine that wouldhelp him get around the royal gardens faster: two same-size in-line wheels, the front one steerable, mounted in a frame which youstraddled. The device was propelled by pushing your feet againstthe ground, thus rolling yourself and the device forward in a sort ofgliding walk. The machine became known as the Draisienne orhobby horse. It was made entirely of wood. This enjoyed a shortlived popularity as a fad, not being practical for transportation inany other place than a well maintained pathway such as in a parkor garden.
  5. 5. The laufmaschine later renamedvelocipede(latin for fast foot) was an improvedversion of the celerifere since it was equippedwith a steering mechanism and the front wheelcould enable the user to turn into the desiredirection. However it still needs to be propelledusing feet and was not balanced. It could onlybe use in good surface .
  6. 6. The two-wheeled bicycle as we know it today was invented inDumfriesshire, Scotland, in 1839 by a blacksmith named KirkpatrickMacmillan. It had a steerable 30-inch front wheel and a 40-inch rearwheel. This bicycle had no pedals or chain-activated gears. Therewere, instead, two foot pedals attached to rods that connected to theback wheel. The alternate movement of rods on either side propelledthe bicycle. Unfortunately for Macmillan, his invention never became popular. Itwas left to a French father-and-son team, Pierre and Ernest Michaux,to build the bicycle from which the present popularity of the vehicleis derived. By 1865 the Michaux family was producing 400 bicycles ayear.
  7. 7. The bone shaker had a wooden frame and the woodwheels had iron rims. This is an improved version ofthe laufmaschine since it had its own mechanism topropel it (pedals) but no brakes and was extremelyuncomfortable to ride.
  8. 8. FOR MEN FOR WOMENThe Penny Farthing is also referred to as the "High"or "Ordinary" bicycle, and the first one wasinvented in 1871 by British engineer, James Starley.The Penny Farthing came after the development ofthe French "Velocipede", and other versions of earlybikes. However, the Penny Farthing was the firstreally efficient bicycle, consisting of a small rearwheel and large front wheel pivoting on a simpletubular frame with tires of rubber.
  9. 9. The Ordinary bicycle wasa successfulimprovement since itmoved faster with itsnew high wheels but thiscan also be proved to bea disadvantage as thebicycle would easily falldown when using thesteering mechanism(this apply only for mansince womenversion(tricycle)) whichwas released in 1876had three wheels whichgave additional support. MAN FALLING FROM A HIGH WHEEL
  10. 10.  John Kemp Starley designed the revolutionary safety bicycle. The main principles which guided him into making this bicycle were to place the rider at the proper distance from the ground, to place the seat in the right position in relation to the pedals and to place the handles in such a position in relation to the seat that the rider could exert the greatest force upon the pedals with the least amount of fatigue. These principles led Starley to design the lightest, strongest, most reasonably priced, most rigid, most compact and ergonomically most efficient shape the bicycle frame could be. The bicycle was chain driven, rear wheel drive with two similar size wheels and with a diamond frame. In 1896, he floated J.K.Starley & Co as the Rover Cycle Company. The capital financed the construction of the largest cycle works in Coventry, England then the global centre of bicycle manufacturing.
  11. 11. The safety bike has all the characteristics of the
  12. 12. The folding is often thought to be invented in the late19,s but it was invented even before the invention of themodern/safety bike. This types of bike was first inventedfor the military since they could easily easily betransported in their backs.
  13. 13. Military interest in bicycles arose in the 1890s, and theFrench army and others deployed folding bikes forbicycle infantry use. In 1900, Mikael Pedersendeveloped a folding version of his Pedersen bicycle forthe British army that weighed 15 pounds and had24 inch wheels. It included a rifle rack and was used inthe Second World War.
  14. 14.  The original bicycle was made by hand using wooden parts As time passed improvements were made because society was evolving and becoming more technologically advanced New methods and materials were used because it made the bike cheaper and easier to manufacture
  15. 15.  1816-Steering 1863-Pedals added 1870-The first all metal bike is manufactured 1879-Chain-driven bike was is patented 1890-Gears added to bicycles 1894-Bikes made lighter by using bamboo 1984-More complex gears allow bikes to have up to 24 speeds 2002-Up to 30 speed gears
  16. 16.  1817-Everyday people begin to use bikes 1863- Bikes become popular once more, mostly in cities 1870- The high wheeler become popular with wealthier people because of its expensive metal frame 1890- The cheaper safety bike allows common people to take up biking 1894- The first bike messengers are employed due to a railway strike which stopped mail delivery 1920- The kids bike is introduced, greatly expanding the biking community 1958-1978- Bicycle boom
  17. 17.  1958-Women first race in the World Championships 1962-People begin using bikes for recreation and fitness 1970-Bicycles become popular modes of transport due to awareness of pollution, especially around college and campuses 1973-1978-Rising gas prices cause people to use bikes as transportation
  18. 18.  Walking and horses were replaced by the use of bicycle as personal transportation The bicycle created a faster paced society Bikes helped enforce the concept equality as bike manufacturers began marketing to women Women’s clothing styles continued to evolved to accommodate lifestyle changes due to the growing popularity of bicycles among women Due to their maneuverability the military incorporated the bicycle into their operations
  19. 19.  When bicycles were first invented there was not much impact on the environment because bicycle do not give off pollution In the 1970’s pollution became a growing issue and bicycles became more popular Bicycles are used as an alternative today because of expensive gas prices and environmental concerns
  20. 20. Features include: Battery assisted motor Run by solar panels Plays music Puncture proof self inflating tires Mini-computer to show calories burned, etc.Cost: If sold right now it would cost around $771,350 If sold after being mass produced cost would be around $3,085
