" Effizienzmessung: Geschwindigkeit / Energie



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) !
