"Other than the rider's training, genetic make up and competitiveness, the bicycle is the key aspect in speed and efficiency. This bicycle, called "the Ultimate", along with its rider Bruce Bursford, broke the world speed record of 334.6 km/h. This design was made aerodynamically efficient to cut down wind resistance. Just a gentle breeze? No, 90% of the resistance you feel is from the wind. This aerodynamic drag is made up of air pressure drag and direct friction, which pulls you backwards. Thus a drafting technique is used. The cyclist rides behind a larger vehicle or another cyclist that cuts through the air and 40% of the cyclist's energy is conserved. It is proven that cycling is the most efficient way of traveling because it takes only 100 calories for a cyclist to burn, for a result of 4828.03 m, while a car would die out after 85.34 m with the same amount of energy.
