World Bicycle Day 2027 is on Thursday, June 3, 2027. The United Nations designated June 3 in 2018 to recognize the bicycle as a simple, affordable, and clean means of sustainable transport.
World Bicycle Day 2027 is the 10th UN observance of the day, first held on Sunday, June 3, 2018. There are two “Bicycle Days”, and they mark unrelated events.
World Bicycle Day on June 3 is a UN observance about sustainable transport. “Bicycle Day” on April 19 marks Swiss chemist Albert Hofmann’s 1943 bicycle ride home after the first intentional dose of LSD. Many people mix the two.
A second common confusion: the UN does not publish an official annual theme, although themes for each year circulate widely online.
This page gives the 2027 to 2031 dates, the UN resolution, the campaign that created the day, and the history of the bicycle since 1817.

When is World Bicycle Day 2027?
World Bicycle Day 2027 falls on Thursday, June 3, 2027. UN General Assembly resolution A/RES/72/272 fixes the date at June 3 every year, so only the weekday changes.
The table below lists the date for the next five years, with weekdays.
| Year | Date | Weekday |
|---|---|---|
| 2027 | June 3, 2027 | Thursday |
| 2028 | June 3, 2028 | Saturday |
| 2029 | June 3, 2029 | Sunday |
| 2030 | June 3, 2030 | Monday |
| 2031 | June 3, 2031 | Tuesday |
World Bicycle Day is not a public holiday in any country. In 2028 and 2029, it falls on a weekend, which suits the group bicycle rides the UN resolution encourages.
Is there an official World Bicycle Day 2027 theme?
The United Nations does not set an official annual theme for World Bicycle Day. Its observance page describes standing focus areas rather than a yearly slogan:
- Sustainable transport and climate action
- Health and physical activity
- The Sustainable Development Goals
- Health equity and access for vulnerable people
- Infrastructure for walking and cycling
Themes published for particular years, such as “Cycling for a Greener Future”, come from news sites, exam-preparation sites and national organizers, not from the UN.
A government, city or cycling federation may still choose its own theme for local events. Check the organizer’s own announcement before quoting a 2027 theme as official.
What does World Bicycle Day commemorate?
World Bicycle Day recognizes the bicycle’s uniqueness, longevity and versatility, and its value as a simple, affordable, reliable, clean and environmentally sustainable means of transport (United Nations).
It does not mark a historical anniversary. June 3 was chosen as a fixed date for the observance itself.
The resolution behind World Bicycle Day
The UN General Assembly adopted resolution A/RES/72/272 on Thursday, April 12, 2018. Turkmenistan led the resolution, about 56 countries co-sponsored it, and it was adopted with the support of all 193 UN member states (World Bank).
It encourages governments and other stakeholders to promote the bicycle as a means of:
- fostering sustainable development
- strengthening education, including physical education
- promoting health and preventing disease
- promoting tolerance, mutual understanding and respect
- facilitating social inclusion and a culture of peace
A second resolution, A/RES/76/255, adopted on Tuesday, March 15, 2022, calls for cycling to be integrated into public transport systems for sustainable development.
Leszek Sibilski’s campaign
The idea for World Bicycle Day came from Leszek Sibilski, a Polish-American sociologist and former member of the Polish national cycling team for 10 years.
He holds a PhD in applied sociology specializing in social movements. The table below traces the campaign from his first blog post to the UN vote.
| Date | Step |
|---|---|
| February 2015 | Sibilski publishes “Cycling is Everyone’s Business” |
| February 2016 | He publishes “Why is there no World Day for the Bicycle” |
| 2016 | He presents the idea at the “Scientists for Cycling” colloquium in Taipei |
| Late November 2017 | He connects with Turkmenistan’s mission to the UN |
| April 12, 2018 | The General Assembly adopts A/RES/72/272 |
| June 3, 2018 | First World Bicycle Day |
From first blog post to UN vote took just over three years. The Sustainable Mobility for All initiative (SuM4All) backed the campaign.
A short history of the bicycle
The bicycle dates to 1817, when German inventor Karl Drais rode his “Laufmaschine” (“running machine”) about 7 kilometres from Mannheim towards Schwetzingen and back in a little over an hour, on Thursday, June 12, 1817 (Wikipedia).
The machine had no pedals: the rider pushed along the ground with their feet. It was later known as the velocipede, draisine, hobby horse, or dandy horse.
The table below gives the key dates connecting Drais’s machine to the UN observance.
| Year | Milestone |
|---|---|
| 1817 | Karl Drais makes the first ride on his Laufmaschine in Mannheim |
| 1818 | Drais receives a grand-ducal privilege protecting his invention in Baden for 10 years |
| 2017 | 200th anniversary of Drais’s first ride |
| 2018 | UN adopts A/RES/72/272; first World Bicycle Day |
| 2022 | UN adopts A/RES/76/255 on cycling and public transport |
| 2027 | 10th World Bicycle Day; 210 years since Drais’s ride |
The UN resolution’s reference to the bicycle being “in use for two centuries” points back to this 1817 ride.
How it is observed
World Bicycle Day is observed through group rides, cycling events, and government and city campaigns that promote cycling for transport and health. The UN resolution explicitly welcomes bicycle rides organized at national and local levels (United Nations). Common activities include:
- Group rides organized by cities, cycling clubs and embassies
- Cycle-to-work and cycle-to-school campaigns, often linked to national health programmes
- Announcements of new cycle lanes or bike-share schemes timed to the day
- Accessibility events promoting adapted bicycles for people with disabilities
- Retailer promotions, sometimes advertised as “World Bike Day sales”
Retail sales are commercial promotions run by shops and brands. They are not part of the UN observance and have no official link to it.
What World Bicycle Day is not
World Bicycle Day is the UN’s June 3 observance of the bicycle as sustainable transport. It is not the April 19 “Bicycle Day”, which marks the history of LSD. The two share a name and nothing else. The table below sets them side by side with other cycling and environment days.
| Observance | Date | Designated by | What it marks |
|---|---|---|---|
| World Bicycle Day | June 3 | UN General Assembly, A/RES/72/272 (2018) | The bicycle as sustainable transport |
| Bicycle Day | April 19 | Thomas Roberts (1985), informal | Albert Hofmann’s 1943 ride after taking LSD |
| World Environment Day | June 5 | United Nations Environment Programme | The global environment |
| Earth Day | April 22 | Earth Day Network | The global environment |
Why April 19 is called Bicycle Day
April 19 is called Bicycle Day because on April 19, 1943, Swiss chemist Albert Hofmann took a deliberate 250-microgram dose of LSD in Basel and rode his bicycle home as its effects began (Blossom).
He had first been exposed to the substance accidentally three days earlier, on April 16, 1943. The informal observance was created by Thomas Roberts in 1985. In 2027, April 19 falls on a Monday, 45 days before World Bicycle Day.
The April observance has no UN or government status. Pages that list April 19 as “World Bicycle Day” are mixing the two.
Other early-summer UN days fall close to World Bicycle Day. World Environment Day 2027 follows two days later, on Saturday, June 5. World Otter Day 2027 falls eight days earlier, on Wednesday, May 26. Earth Day 2027 is on Thursday, April 22.
Frequently asked questions
Why is World Bicycle Day celebrated?
World Bicycle Day is celebrated to recognize the bicycle as a simple, affordable, reliable, and clean means of sustainable transport. The UN General Assembly created it in April 2018 and encourages countries to promote cycling for health, education, social inclusion and climate action. The first World Bicycle Day was held on June 3, 2018.
What is the theme of World Bicycle Day 2027?
The United Nations does not set an official yearly theme for World Bicycle Day. Its observance page lists standing focus areas instead, including sustainable transport, health and climate action. Themes published online for specific years come from news and education sites or local organizers, so check the organizer’s own announcement before treating one as official.
Who started World Bicycle Day?
World Bicycle Day was proposed by Leszek Sibilski, a Polish-American sociologist and former member of Poland’s national cycling team. He campaigned from 2015, and Turkmenistan led the UN resolution with about 56 co-sponsors. The General Assembly adopted resolution A/RES/72/272 on April 12, 2018, with the support of all 193 member states.
Why is April 19 called Bicycle Day?
April 19 is called Bicycle Day because on April 19, 1943, chemist Albert Hofmann rode his bicycle home in Basel after taking the first deliberate dose of LSD. Thomas Roberts created the informal observance in 1985. It is unrelated to the UN’s World Bicycle Day, which is held on June 3.
What is the oldest bicycle in the world?
The oldest bicycle design is Karl Drais’s Laufmaschine, or running machine, first ridden in Mannheim, Germany, on June 12, 1817. It had two wheels and steering but no pedals, so riders pushed along the ground with their feet. It was also known as the draisine, velocipede, hobby horse, and dandy horse.
Is World Bicycle Day a public holiday?
No. It is a UN observance, not a public holiday, and no country closes schools or offices for it. In 2027, it falls on Thursday, June 3, a normal working day in most countries. Many cities and cycling groups hold rides on the day itself or the following weekend.
