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.
The French vélocipède, made of iron and wood, developed into the "penny-farthing" (historically known as an "ordinary bicycle", a retronym, since there was then no other kind). It featured a tubular steel frame on which were mounted wire-spoked wheels with solid rubber tires. These bicycles were difficult to ride due to their high seat and poor weight distribution. In 1868 Rowley Turner, a sales agent of the Coventry Sewing Machine Company (which soon became the Coventry Machinists Company), brought a Michaux cycle to Coventry, England. His uncle, Josiah Turner, and business partner James Starley, used this as a basis for the Coventry Model in what became Britains first cycle factory.
Increase your brain power. Need your grey matter to sparkle? Then get pedalling. Researchers from the University of Illinois found that a ﬁve percent improvement in cardio-respiratory ﬁtness from cycling led to an improvement of up to 15 percent in mental tests. That`s because cycling helps build new brain cells in the hippocampus — the region responsible for memory, which deteriorates from the age of 30. “It boosts blood ﬂow and oxygen to the brain, which ﬁres and regenerates receptors, explaining how exercise helps ward off Alzheimer`s,” says the study`s author, Professor Arthur Kramer.
