Make friends and stay healthy. The social side of riding could be doing you as much good as the actual exercise and health benefits. University of California researchers found socialising releases the hormone oxytocin, which buffers the ‘ﬁght or ﬂight` response. Another nine-year study from Harvard Medical School found those with the most friends cut the risk of an early death by more than 60 percent, reducing blood pressure and strengthening their immune system. The results were so signiﬁcant that the researchers concluded not having close friends or conﬁdants is as detrimental to your health as smoking or carrying extra weight. Add in the ﬁtness element of cycling too and you`re onto a winner.
Get (a legal) high. Once a thing of myth, the infamous ‘runner`s high` has been proven beyond doubt by German scientists. Yet despite the name, this high is applicable to all endurance athletes. University of Bonn neurologists visualised endorphins in the brains of 10 volunteers before and after a two-hour cardio session using a technique called positive emission tomography (PET).
The dwarf ordinary addressed some of these faults by reducing the front wheel diameter and setting the seat further back. This, in turn, required gearing—effected in a variety of ways—to efficiently use pedal power. Having to both pedal and steer via the front wheel remained a problem. Englishman J. K. Starley (nephew of James Starley), J. H. Lawson, and Shergold solved this problem by introducing the chain drive (originated by the unsuccessful "bicyclette" of Englishman Henry Lawson), connecting the frame-mounted cranks to the rear wheel.
