When was Bicycle Day Started? Unveiling the Origins.

Bicycle day started on april 19, 1943. On april 19, 1943, swiss scientist, albert hofmann, ingested a small amount of lysergic acid diethylamide (lsd) and rode his bicycle home.

This day, known as bicycle day, marked the first intentional lsd trip and is celebrated by psychonauts and enthusiasts around the world. The psychedelic effects hofmann experienced shifted the course of psychedelic research and inspired a wave of interest in the substance.

The day has become an annual moment of celebration and reflection with events and festivals dedicated to its commemoration. While some view it as a day to honor hofmann’s legacy, for others it simply represents the experience of a journey into altered states of consciousness.

The Discovery Of Lsd

Albert hofmann, a swiss chemist, discovered lsd in 1943, while he was studying the hallucinogenic properties of the plant, ergot. In his laboratory, he accidentally ingested a small amount of lsd, experiencing its hallucinogenic effects. Unimaginable colors and geometric patterns engulfed him.

He became anxious and frightened but rode his bicycle home, and his research assistant walked him home. In the following days, he ingested more lsd, studying its effects. This led to the discovery of psychoactive drugs, which transformed the psychiatric industry.

Today, the bike ride celebrates its anniversary as bicycle day, celebrated by acid enthusiasts worldwide. Hofmann’s discovery of lsd kick-started a new era of psychedelic experimentation, and he remains a forefather of the modern counterculture movement.

The First Lsd Trip

In 1943, chemist albert hofmann made a conscious decision to ingest a small dose of lsd-25, a substance he discovered five years earlier. On his bicycle ride home, he began experiencing intense and vivid hallucinations. Hofmann’s personal experiment was unprecedented, and he has since been known as the first person to intentionally consume lsd.

His experience gave birth to “bicycle day,” which is celebrated annually on april 19th. In the years since, lsd has been the subject of intense debate and study, and its potential benefits and risks have been widely discussed. Nevertheless, the legacy of hofmann’s ride and the creation of bicycle day have cemented the place of lsd in popular culture and the history of science.

The Celebration Of Bicycle Day

Bicycle day began on april 19th, 1943, when dr. Albert hofmann intentionally ingested lsd and then rode his bicycle home. Today, the day is celebrated by cyclists all around the world. Popular events range from organized mass rides to festivals.

Perhaps the most unique tradition is the annual bicycle parade held in santa cruz, california, where participants deck out their bikes in wild, psychedelic decorations. Over time, the celebration has evolved into a broader celebration of alternative transportation and sustainability.

People use bicycle day to advocate for cycling as a healthy, low-carbon form of transportation, while also acknowledging the spiritual and cultural significance of the day. Whether you participate in a ride or simply go for a spin around your town, bicycle day is a great opportunity to celebrate the humble bicycle and all that it represents.

The Impact Of Bicycle Day

Bicycle day is celebrated on april 19th every year to commemorate albert hofmann’s discovery of lsd’s psychoactive properties. This discovery had a significant impact on culture and history. Spiritual and artistic communities have embraced lsd, with many artists, musicians, and writers crediting the drug with enhancing their creativity and spiritual journeys.

Additionally, the cultural fascination with psychedelics led to extensive research in the 1950s and 60s, hoping to unlock the therapeutic potential of lsd. However, the government crackdown on drugs ended much of the research, contributing to the drug’s reputation as a dangerous substance.

Despite this, in recent years, mdma and psilocybin have been gaining attention in the scientific community as potential treatments for mental health conditions. Bicycle day is a reminder of the complex history of psychedelics and their ongoing impact on science and culture.


Bicycle day is a significant part of psychedelic history that has been celebrated for over 70 years now. It was on april 19, 1943, when dr. Albert hofmann, a swiss chemist, first discovered the mind-altering properties of lsd. Since then, this day has been commemorated as bicycle day, in honor of hofmann’s famous bicycle ride home after he inadvertently ingested lsd.

Throughout its history, bicycle day has come to symbolize a celebration of the therapeutic and mind-expanding potential of lsd. It is a day that allows us to reflect on the transformative power of psychedelics and the many ways they continue to influence our understanding of the mind, spirituality, and human consciousness.

Thus, even after so many years, bicycle day remains an essential marker, reminding us of the importance of our scientific heritage and the continuous evolution of human consciousness.
