Cycling takes up the least energy among all transport options. Did you know that on flat ground, one hundred calories can power a cyclist for three miles, but it would only power a car 85 meters! The above fact is from the website Science of Cycling.
Ever wanted to know the science behind gear ratios, carbon frames, and bike design? Check out the website for more interesting facts.
Statistics have also shown a link between cycling and a country's health. Only 1% of urban travel in the US is by bicycle, and 30.6% of adults there are obese. This contrasts with the Netherlands where 28% of urban travel is via a bike, and only 10% are obese. See World Watch for more information
