4. Why is the bicycle the most efficient way to travel? How do your muscles work?  Bicycles are the best way to travel because it’s the best way to save gas and to gain energy.  A cyclist's legs provide the power for cycling. Muscle attached to the thighbone (femur) and the shinbone (tibia) do the majority of the work. Your thighbone works like a lever and if it's longer than your shinbone it will provide extra leverage on each stroke of the pedals. The length of your thighbone is determined by genetics, so if you have short thighbones you can blame your parents. The length of the thighbone is not the whole story, though--it takes muscles to move those bones.
