The first mechanically-propelled, two-wheeled vehicle may have been built by Kirkpatrick MacMillan, a Scottish blacksmith, in 1839, although the claim is often disputed. He is also associated with the first recorded instance of a cycling traffic offense, when a Glasgow newspaper in 1842 reported an accident in which an anonymous "gentleman from Dumfries-shire bestride a velocipede of ingenious design" knocked over a little girl in Glasgow and was fined five shillings.
Avoid pollution. You`d think a city cyclist would suck up much more pollution than the drivers and passengers in the vehicles chucking out the noxious gases. Not so, according to a study carried out by Imperial College London. Researchers found that passengers in buses, taxis and cars inhaled substantially more pollution than cyclists and pedestrians. On average, taxi passengers were exposed to more than 100,000 ultraﬁne particles — which can settle in the lungs and damage cells — per cubic centimetre. Bus passengers sucked up just under 100,000 and people in cars inhaled about 40,000. Cyclists, meanwhile, were exposed to just 8,000 ultraﬁne particles per cubic centimetre. It`s thought that cyclists breathe in fewer fumes because we ride at the edge of the road and, unlike drivers, aren`t directly in the line of exhaust smoke.
History of the bicycle. Wooden draisine (around 1820), the first two-wheeler and as such the archetype of the bicycle. The "Dandy horse", also called Draisienne or Laufmaschine, was the first human means of transport to use only two wheels in tandem and was invented by the German Baron Karl von Drais. It is regarded as the modern bicycles forerunner; Drais introduced it to the public in Mannheim in summer 1817 and in Paris in 1818. Its rider sat astride a wooden frame supported by two in-line wheels and pushed the vehicle along with his or her feet while steering the front wheel.
Save the planet. Twenty bicycles can be parked in the same space as one car. It takes around ﬁve percent of the materials and energy used to make a car to build a bike, and a bike produces zero pollution. Bikes are efﬁcient, too — you travel around three times as fast as walking for the same amount of energy and, taking into account the ‘fuel` you put in your ‘engine`, you do the equivalent of 2,924 miles to the gallon. You have your weight ratio to thank: you`re about six times heavier than your bike, but a car is 20 times heavier than you.
Make creative breakthroughs. Writers, musicians, artists, top executives and all kinds of other professionals use exercise to solve mental blocks and make decisions — including Jeremy Paxman, Sir Alan Sugar and Spandau Ballet. A study found that just 25 minutes of aerobic exercise boosts at least one measure of creative thinking. Credit goes to the ﬂow of oxygen to your grey matter when it matters most, sparking your neurons and giving you breathing space away from the muddle and pressures of ‘real life`.
