Vintage Bicycle Silhouette #6576175 (License: Personal Use)

This black-and-white technical illustration depicts a safety bicycle from the 1880s-1890s, notable for replacing the dangerous high-wheel penny-farthing with two equally sized wheels, a chain-driven rear wheel, and a comfortable sprung saddle. Key features include a diamond frame, rod-operated brake levers, fenders, and spoked wheels with tensioned wire spokes-hallmarks of early modern cycling engineering. The drawing emphasizes precision craftsmanship typical of period patent or catalog illustrations.
