The Svea Velocipede with vertical pedal arrangement and locking hubs was introduced in 1892 by the Swedish engineers Fredrik Ljungström and Birger Ljungström. It attracted attention at the World Fair and was produced in a few thousand units. By the turn of the century, cycling clubs flourished on both sides of the Atlantic, and touring and racing became widely popular.
You can get fit without trying too hard. Regular, everyday cycling has huge beneﬁts that can justify you binning your wallet-crippling gym membership. According to the National Forum for Coronary Heart Disease Foundation in the US, regular cyclists enjoy a ﬁtness level equal to that of a person who`s 10 years younger.
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.
Comparing the pre- and post-run scans, they found evidence of more opiate binding of the happy hormone in the frontal and limbic regions of the brain — areas known to be involved in emotional processing and dealing with stress. “There`s a direct link between feelings of wellbeing and exercise, and for the ﬁrst time this study proves the physiological mechanism behind that,” explains study co-ordinator Professor Henning Boecker.
Bicycles and horse buggies were the two mainstays of private transportation just prior to the automobile, and the grading of smooth roads in the late 19th century was stimulated by the widespread advertising, production, and use of these devices. More than 1 billion bicycles have been manufactured worldwide as of the early 21st century. Bicycles are the most common vehicle of any kind in the world, and the most numerous model of any kind of vehicle, whether human-powered or motor vehicle, is the Chinese Flying Pigeon, with numbers exceeding 500 million. The next most numerous vehicle, the Honda Super Cub motorcycle, has more than 60 million units made, while most produced car, the Toyota Corolla, has reached 35 million and counting.
