ELI5, How am I able to go farther and faster on my bicycle than by walking, considering I have to move the mass of the bike, as well as the loss of energy to friction from the gears and wheels?

The bike has two advantages over your legs. One, it’s on wheels, which gives you the ability to coast on flats or down hills. Second, it has gears, which gives you mechanical advantage. At your highest speeds, each single revolution of your pedals results in around 5 revolutions of your back wheel
