it;s the most energy-efficient means of human transport

mostly because wheels use almost no energy to roll

unlike feet and walking or running

Since it's made up of simple machines, does it spread the work so you do double the distance and use less effort?

Bicycles are a simple gear-and-chain mechanism. You turn the pedals connected to the larger of two gears, which there in turns the chain and the smaller gear. This simple large-to-small gear ration allows for a higher number of rotations of the wheel per human leg rotation, using less energy than walking to travel at a higher speed.
