Historical Safety Bicycle Design - Evolution of the Modern Bike #2371715 (License: Personal Use)

This detailed line drawing depicts a late-1880s safety bicycle, notable for its equal-sized wheels, diamond-shaped frame, and direct chain drive to the rear wheel-revolutionizing cycling safety and accessibility. The front brake lever, mounted on the handlebar, and the simple saddle reflect early ergonomic considerations. Unlike the high-wheel penny-farthing, this design enabled riders of all ages and genders to cycle confidently.
