The "High Wheel," also known as the penny-farthing, is a type of bicycle that was popular in the late 19th century. It features a large front wheel and a smaller rear wheel, which gives it a distinctive appearance. The design allows for greater speed, as the size of the front wheel determines how far the bicycle travels with each pedal stroke. Riders of the high wheel often faced challenges due to its height and balance requirements. The bicycle's design made it difficult to mount and dismount, leading to the term "header" for falls that occurred when the rider went over the handlebars. Despite its risks, the high wheel remains an iconic symbol of early cycling history and innovation.
