No one is surewho invented this popular two-wheeled machine, but it was probably either the German Karl vonDrais, in 1817, or the American W K Clarkson, in 1819.The early models didn't look much like the bicycles of today. The front wheel was muchbigger than the back one, and also there weren't any pedals — riders had to move themselvesforward by pushing their feet against the ground. Pedals finally arrived in the 1840s, and in 1879 anEnglishman named Henry Lawson had the idea of connecting them to the back wheel with a chain.Gears, which made things much easier for those cycling uphill, first appeared in the 1890s.There are now approximately one billion bicycles in the world — more than twice the totalnumber of cars – and they are the main form of transport in some developing countries. They have tocompete with cars on the streets of all the world’s cities and two forms of transport don’t always mixwell. In London in 2005, for example, over 300 cyclists were either killed or seriously injured inaccidents involving cars. Even though bicycles are much more environmentally friendly than cars,most governments don't do much to encourage people to ride rather than drive. In China, which isfamous for having a huge number of bicycles (about 200 million), the authorities in the city ofShanghai even banned cycling for a while in 2003.Cycling is on the rise in the United Kingdom, and the number of annual journeys made bybike in London has increased 50% over the last five years. Experts say there is a mixture of reasonsfor this boom: concerns about the environment, the desire to keep fit, and also the fact that cycling isoften not only cheaper but also quicker than travelling by car.However, although one in three British adults owns a bicycle, they still don't use them nearlyas much as they could. Bikes are used for a mere 2% of journeys in the UK, while the figure for theNetherlands is an impressive 27%.Cycling is becoming more popular as a competitive sport, and the most famous race is ofcourse the three-week Tour de France, which takes place every July. American Lance Armstrongwon it every year from 1999 to 2005 --one of the greatest individual sporting achievements of alltime.(adapted from Handouts for B2, University of Linguistics and International Studies, 2017)
