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.
Get better at any sport. Whether you want to keep in prime shape or just improve your weekly tennis game, a stint in the saddle is the way to begin. A recent medical study from Norway carried the title Aerobic Endurance Training Improves Soccer Performance, which makes it pretty clear that the knock-on beneﬁts to other sports and activities are immense.
It`s good breeding. A ‘bun in the oven` could beneﬁt from your riding as much as you. According to research from Michigan University in the US, mums-to-be who regularly exercise during pregnancy have an easier, less complicated labour, recover faster and enjoy better overall mood throughout the nine months. Your pride and joy also has a 50 percent lower chance of becoming obese and enjoys better in-utero neurodevelopment. “There`s no doubt that moderate exercise such as cycling during pregnancy helps condition the mother and protect the foetus,” says Patrick O`Brien, a spokesman for the Royal College of Obstetricians and Gynaecologists.
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.
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.
