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.
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.
Live longer. King`s College London compared over 2,400 identical twins and found those who did the equivalent of just three 45-minute rides a week were nine years ‘biologically younger` even after discounting other inﬂuences, such as body mass index (BMI) and smoking. “Those who exercise regularly are at signiﬁcantly lower risk of cardiovascular disease, type two diabetes, all types of cancer, high blood pressure and obesity,” says Dr Lynn Cherkas, who conducted the research. “The body becomes much more efﬁcient at defending itself and regenerating new cells.”
