Further innovations increased comfort and ushered in a second bicycle craze, the 1890s Golden Age of Bicycles. In 1888, Scotsman John Boyd Dunlop introduced the first practical pneumatic tire, which soon became universal. Soon after, the rear freewheel was developed, enabling the rider to coast. This refinement led to the 1890s invention of coaster brakes. Dérailleur gears and hand-operated Bowden cable-pull brakes were also developed during these years, but were only slowly adopted by casual riders.
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.
Cycling improves your sex life. Being more physically active improves your vascular health, which has the knock-on effect of boosting your sex drive, according to health experts in the US. One study from Cornell University also concluded that male athletes have the sexual prowess of men two to ﬁve years younger, with physically ﬁt females delaying the menopause by a similar amount of time. Meanwhile, research carried out at Harvard University found that men aged over 50 who cycle for at least three hours a week have a 30 percent lower risk of impotence than those who do little exercise. It`s official: cycling is good for your sex life.
