“Man on a bicycle can go three or four times faster than the pedestrian, but uses five times less energy in the process. He carries one gram of his weight over a kilometre of flat road at an expense of only 0.15 calories. The bicycle is the perfect transducer to match man’s metabolic energy to the impedance of locomotion. Equipped with this tool, man outstrips the efficiency of not only all machines but all other animals as well.
What about uphill or uneven terrain. going downhill on bike is very efficient too. You can test this by rolling a ball down even a slight grade. Yes, in artificial conditions bikes are better.
