Why does a longer bicycle ramp have better mechanical advantage than a shorter one?
Mechanical advantage is defined as the input force divided by the output force. If both ramps have the same final height, the longer one will generally have the greater mechanical advantage because it requires less overall work from the cyclist to raise the bicycle to a higher potential energy in a uniform gravitational field. The limit to this exists where the ramp becomes so long that it actually takes more energy to traverse than the short since you must account for the work required to maintain forward motion against friction and the climb against gravity. This limiting distance is related to the final height of the ramp.
