    One thing to account for is that humans are very inefficient at converting food into energy output. Only about 25% efficient to be precise. So you need to eat about 4 times more calories than you end up outputting into the bicycle.

    The same thing applies to ICE cars, their engines are also very inefficient. EVs however reach an efficiency of 80-90%, they only end up using more energy than a bicycle because of how much faster you usually drive them. But if you drove an EV at the same speed you would ride a bicycle they would be vastly more efficient. And that’s not even accounting for the amount of energy used to produce food in the first place, which is a lot higher than the energy content of said food.

    The superior choice is obviously an electric bicycle though when you want to have the most sustainable transportation, you get all of the efficiency gains from a battery operated motor, whilst still having the low weight and drag of a bicycle

    I disagree. Processing power may be similar, but Nvidia still outperforms with raytracing, and more importantly DLSS.

    Whats the point of having the same processing power, when Nvidia still gets more than double the FPS in any game that supports DLSS
