Describe how you would measure the mechanical advantage of a bicycle.
Can't be answered. Different bikes have different gears, and with different gears come different mechanical advantage. A MTB can have an adjustable mechanical advantage ranging from 0.75:1 - 1:4
Machinal advantage, also known as mechanical advantage, refers to the ratio of the force produced by a machine to the force applied to it. A machine can be useful even its machinal advantage is less than 1.

Speed. It's nice to be able to drive the wheel faster than the rpm's your legs can produce on the front gears.
A bicycle is powered by human exertion and a motorbike by mechanical power.

Kinda-sorta. The bicycle is important for the bicycle business, but has little influence on other areas.
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.

Friction
It converts mechanical energy into electric energy. .
