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.
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?
You`ll sleep more deeply. An early morning ride might tire you out in the short term, but it`ll help you catch some quality shut-eye when you get back to your pillow. Stanford University School of Medicine researchers asked sedentary insomnia sufferers to cycle for 20-30 minutes every other day. The result? The time required for the insomniacs to fall asleep was reduced by half, and sleep time increased by almost an hour. “Exercising outside exposes you to daylight,” explains Professor Jim Horne from Loughborough University`s Sleep Research Centre. “This helps get your circadian rhythm back in sync, and also rids your body of cortisol, the stress hormone that can prevent deep, regenerative sleep.”
