How does the apparently small amount of material which comprises the spokes provide the required sturdiness to handle the physics of a human on a bike?

Tension.
None of those bars is ever pushed, even resting they’re stretched. When someone puts weight on the wheel, the spokes at the bottom see less tension, and the ones at the top see more, which effectively means that the center is hanging from the rim while all the spokes on the sides and bottom are keeping the rim circular.
