old-timey-high-wheeler-bicycles-were-also-known

Old-timey ‘high-wheeler’ bicycles were also known as ‘penny farthings’, because people thought they looked like the largest (penny) and smallest (farthing) coins of the day rolling after each other. The reason one wheel was oversized was that they had no gears or chains, and the only way to make them go faster was by having a big front wheel. Source Source 2
