The bicycle has a history that goes back about 600 years and is quite different than the bike as we know today.The first bike was invented in 1418, an Italian engineer, Giovanni Fontana.He constructed a human-powered deviceconsisting of four wheels and a loop of rope connected by gears, according to the International Bicycle Fund (IBF).In 1813, about 400 years after Fontana built his wheeled contraption, a German aristocrat and inventor named Karl von Drais began work on his own version of a Laufmaschine (running machine), a four-wheeled, human-powered vehicle. Then in 1817, Drais debuted a two-wheeled vehicle, known by many names throughout Europe, including Draisienne, dandy horse and hobby horse.
