Cause and effect of how a bike works?

A bike works through the interaction of its components, primarily the pedaling motion of the rider and the gears. When the rider pedals, they apply force to the pedals, which turns the crankset and drives the chain. This motion transfers energy through the gears to the rear wheel, propelling the bike forward. Thus, the cause (pedaling) leads to the effect (movement), with the bike's design facilitating this energy transfer efficiently.
