Penny-Farthing Bicycle

These were the first machines to be called "bicycles".

Penny-farthing, High wheel, high wheeler, and ordinary are all terms used to describe a type of bicycle with a large front wheel and a much smaller rear wheel that was popular after the boneshaker until the development of the safety bicycle, in the 1880s.
The boneshaker was an all wood French design that in combination with the cobblestone roads of the day made for an extremely uncomfortable ride.

About 1870, James Starley, described as the father of the bicycle industry, began producing bicycles based on the French boneshaker, but with front wheels of increasing size, because larger front wheels enabled higher speeds on bicycles limited to direct drive.

Although commonly known as "penny-farthings", this term was probably not used until they were nearly outdated. The first recorded print reference is 1891 in Bicycling News.
It comes from the British penny and farthing coins, one much larger than the other, so that the side view resembles a penny leading a farthing.

For most of their reign, they were simply known as "bicycles".

In the late 1890s, the retronym "ordinary" began to be used, to distinguish them from the emerging safety bicycles, and the term ordinary or Hi-wheel is preferred by many modern enthusiasts.

Although the trend was short-lived, the penny-farthing became a symbol of the late Victorian era. Its popularity also coincided with the birth of cycling as a sport.
