Per gallon of what? ÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷ "It takes less energy to bicycle one mile than it takes to walk a mile. In fact, a bicycle can be up to 5 times more efficient than walking. If we compare the amount of calories burned in bicycling to the number of calories an automobile burns, the difference is astounding. One hundred calories can power a cyclist for three miles, but it would only power a car 280 feet (85 meters)!" (with a .gif image showing) "A comparison of the energy cost of various forms of transportation shows that the bicycle is most energy-efficient." (kcal/km per person) (copied from: http://www.exploratorium.edu/cycling/humanpower1.html) "A bicycle is also the world's most energy efficient mode of travel, using just 35 calories per passenger mile versus 1860 for an average automobile with one occupant."
