That doesn't say anything about the human form: it says something about the human body.
But it's also not very accurate on that count: we are actually very strong compared to mechanical systems of a similar size, weight and energy structure.
You're mistaken. It says something about the shape of humans. Bicycles, which are powered by the human body, show the inferiority of bipedalism to wheels, when it comes to fast and efficient locomotion.
