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.
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.
Save the planet. Twenty bicycles can be parked in the same space as one car. It takes around ﬁve percent of the materials and energy used to make a car to build a bike, and a bike produces zero pollution. Bikes are efﬁcient, too — you travel around three times as fast as walking for the same amount of energy and, taking into account the ‘fuel` you put in your ‘engine`, you do the equivalent of 2,924 miles to the gallon. You have your weight ratio to thank: you`re about six times heavier than your bike, but a car is 20 times heavier than you.
