Bicycle Gear System Diagram - How Chain and Sprockets Transfer Power #1745679 (License: Personal Use)

This technical illustration depicts a simplified bicycle drivetrain with a large front sprocket (chainring) connected via a chain to a smaller rear sprocket (cog), demonstrating gear ratio principles. Blue spokes and red rims emphasize wheel structure, while black chain links show torque transmission from pedals to rear wheel. The diagram is ideal for educational or repair guides explaining mechanical advantage in cycling.

Used on cycling education pages, bike maintenance tutorials, or engineering explainers; targets users seeking to understand gear ratios, drivetrain efficiency, or bicycle mechanics fundamentals.
