Boost your bellows. No prizes for guessing that the lungs work considerably harder than usual when you ride. An adult cycling generally uses 10 times the oxygen they`d need to sit in front of the TV for the same period. Even better, regular cycling will help strengthen your cardiovascular system over time, enabling your heart and lungs to work more efﬁciently and getting more oxygen where it`s needed, quicker. This means you can do more exercise for less effort. How good does that sound?
These models were known as safety bicycles, dwarf safeties, or upright bicycles for their lower seat height and better weight distribution, although without pneumatic tires the ride of the smaller-wheeled bicycle would be much rougher than that of the larger-wheeled variety. Starleys 1885 Rover, manufactured in Coventry is usually described as the first recognizably modern bicycle. Soon the seat tube was added, creating the modern bikes double-triangle diamond frame.
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.
