These models were known as safety bicycles, dwarf safeties, or upright bicycles for their lower seat height and better weight distribution, although without pneumatic tires the ride of the smaller-wheeled bicycle would be much rougher than that of the larger-wheeled variety. Starleys 1885 Rover, manufactured in Coventry is usually described as the first recognizably modern bicycle. Soon the seat tube was added, creating the modern bikes double-triangle diamond frame.
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).
Heal your heart. Studies from Purdue University in the US have shown that regular cycling can cut your risk of heart disease by 50 percent. And according to the British Heart Foundation, around 10,000 fatal heart attacks could be avoided each year if people kept themselves ﬁtter. Cycling just 20 miles a week reduces your risk of heart disease to less than half that of those who take no exercise, it says.
In the early 1860s, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical crank drive with pedals on an enlarged front wheel (the velocipede). Another French inventor named Douglas Grasso had a failed prototype of Pierre Lallements bicycle several years earlier. Several inventions followed using rear-wheel drive, the best known being the rod-driven velocipede by Scotsman Thomas McCall in 1869. In that same year, bicycle wheels with wire spokes were patented by Eugène Meyer of Paris.
Increase your brain power. Need your grey matter to sparkle? Then get pedalling. Researchers from the University of Illinois found that a ﬁve percent improvement in cardio-respiratory ﬁtness from cycling led to an improvement of up to 15 percent in mental tests. That`s because cycling helps build new brain cells in the hippocampus — the region responsible for memory, which deteriorates from the age of 30. “It boosts blood ﬂow and oxygen to the brain, which ﬁres and regenerates receptors, explaining how exercise helps ward off Alzheimer`s,” says the study`s author, Professor Arthur Kramer.
