Origins of the Day
The International Day was established by the United Nations after a campaign led by Polish professor Leszek Sibilski. Between 2015 and 2018, Sibilski advocated for the bicycle to be recognised with its own global day.
His efforts, supported by students at Montgomery College, eventually led to the UN’s formal adoption of World Bicycle Day.
Purpose and Significance
The day emphasises bicycles as a sustainable, eco‑friendly means of transport. It promotes healthy lifestyles through physical exercise, reduces traffic congestion and air pollution, and provides affordable mobility accessible to many. In this way, bicycles are celebrated not only as vehicles but as tools for social and environmental progress.
