World Bicycle Day
Issued by United Nations June 3, 2022

World Bicycle Day draws attention to the benefits of using the bicycle — a simple, affordable, clean and environmentally fit sustainable means of transportation. The bicycle contributes to cleaner air and less congestion and makes education, health care and other social services more accessible to the most vulnerable populations. A sustainable transport system that promotes economic growth, reduces inequalities while bolstering the fight against climate change is critical to achieving the Sustainable Development Goals
