This is a timeline of bicycle transportation, attempting to describe significant events in the development of the technology and use of bicycles.

Big picture

Time period Development summary
Before 19th century Multiple events lead to the development of the bicycle, starting with the invention of the wheel. As early as 500 BC, Chinese engineer Lu Ban is probably the first to mention a pedal powered cycle. During the Italian Renaissance, Giovanni Fontana, Leonardo Da Vinci and his student Gian Giacomo Caprotti lead the development of early prototypes. In the 17th century, Johann Hautsch and Stephan Farffler in Germany contribute with the development of the technology.
19th century The velocipede from 1860 is considered the first true bicycle. John Kemp Starley's Rover Safety Bicycle is regarded as the first model of “modern” bicycle.[1] In the 1860s, several different French inventors develop prototypes with pedals attached to the front wheel.[2] In the 1870s there are several advances in metallurgy, including hollow frame tubes and wire-spoked wheels.[3] From the 1880s onward, manufacturing technology improves even further and allows factories to mass-produce bicycles at lower costs.[4] By 1890, bikes are already popular.[5] The pneumatic tire and the chain drive, followed by the development of gears, revolutionize bicycling in the later century.[6]
1900s–1950s Golden Age of Bicycles. This means of transport becomes one of the primary means of public road transportation. Early bicycle clubs popularize recreational driving across Europe and the United States. Throughout time, the manufacturing costs come down significantly, which increase the use of bicycle all over the world.[7] During World War I, bicycles play a valuable role as the French, British and Germans deploy bicycle regiments and battalions.[1]
1960s onwards The modern age of bicycles starts with the increase of consciousness of the benefits of exercise and energy efficient transport.[7] In the 1960s there's a revival of interest in folding bikes.[8] During the 1970's the so-called Bike Boom occurs in the United States as the general public becomes aware of the value of exercise and energy-efficient transportation.[9] Faster and lighter bicycles are also introduced.[4] In the 1980s, the use of Mountain Bikes and BMXs become popular.[10] Bicycle frames in the 1990s become lighter and stronger.[6]
Present time It is estimated that about 16% of the global population can ride a bicycle. China is the global leader in bicycle production, sales, and export. Dockless bike share systems grow rapidly to involve over 100 cities and millions of bicycles.[11]
