A bicycle, often called a bike or cycle, is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other.
A bicycle rider is called a cyclist or bicyclist. Bicycles were introduced in the 19th century in Europe. The basic shape and configuration of a typical upright, or safety bicycle, has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed for a proliferation of specialized designs for many types of cycling.
3D print of penny-farthing
This is a 3D print, made by RYDA Technology, of a penny-farthing bicycle, also known as a high wheel, high wheeler and ordinary. It is a bicycle type with a large front wheel and much smaller rear wheel. It was popular after the ‘boneshaker’ until the development of the safety bicycle in the 1880s. Although the name penny-farthing is now the most common, it was probably not used until the machines were nearly outdated; the 1st recorded print reference is from 1891 in Bicycling News. It comes from the British penny and farthing coins, one much larger than the other. Donated by Ryda
