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.
Spend quality time with your partner. It doesn`t matter if your paces aren`t perfectly matched, just slow down and enjoy each other`s company. Many couples make one or two riding ‘dates` every week. And it makes sense: exercise helps release feel-good hormones, so after a ride you`ll have a warm feeling towards each other even if he leaves the toilet seat up and her hair is blocking the plughole again.
Avoid pollution. You`d think a city cyclist would suck up much more pollution than the drivers and passengers in the vehicles chucking out the noxious gases. Not so, according to a study carried out by Imperial College London. Researchers found that passengers in buses, taxis and cars inhaled substantially more pollution than cyclists and pedestrians. On average, taxi passengers were exposed to more than 100,000 ultraﬁne particles — which can settle in the lungs and damage cells — per cubic centimetre. Bus passengers sucked up just under 100,000 and people in cars inhaled about 40,000. Cyclists, meanwhile, were exposed to just 8,000 ultraﬁne particles per cubic centimetre. It`s thought that cyclists breathe in fewer fumes because we ride at the edge of the road and, unlike drivers, aren`t directly in the line of exhaust smoke.
