Lose weight by riding your bike. Loads of people who want to shift some heft think that heading out for a jog is the best way to start slimming down. But while running does burn a ton of fat, it`s not kind to you if you`re a little larger than you`d like to be. Think about it — two to three times your body weight goes crashing through your body when your foot strikes the ground. If you weigh 16 stone, that`s a lot of force! Instead, start out on a bike — most of your weight is taken by the saddle, so your skeleton doesn`t take a battering. Running can wait…
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.
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.
