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.
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).
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.”
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.
Bike riding means guilt-free snacks. Upping your salt intake is seldom your doctor`s advice, but in the few days leading up to a big ride or sportive, that`s exactly what you should do. This gives you the perfect excuse to munch on crisps and other salty foods you might normally avoid. The sodium in them helps protect your body against hyponatraemia, a condition caused by drinking too much water without enough sodium that can lead to disorientation, illness and worse.
