"A cyclist can go 3 or 4 times faster than a pedestrian, but uses 5 times less energy. The bicycle is the perfect transducer to match metabolic energy to impedance of locomotion. Equipped with this tool, man outstrips efficiency of not only all machines, but all other animals as well."

@kim_harding I wonder if the high efficiency of the bicycle compared to walking would be reduced when including the energy to maintain a paved road for cycling with an unpaved track for walking?

@herdsoft that would be trying to compare apples with oranges, walking on a paved surface is easier than an unpaved surface, the same is true of cycling
