Designed and built by eight Dutch engineers, the world’s longest rideable bicycle is 180 feet long (55.16 meters), roughly the same length as four double-decker buses.

39-year-old Ivan Schalk had been thinking about building the world’s longest bicycle since reading about it in a Guinness Book of Records when he was a child, but he only embarked upon this project in 2018, as a way to fill up his free time. He knew it wasn’t the kind of thing he could build himself, so he sought the help of like-minded people in his home village of Prinsenbeek, which is apparently well-known in the Netherlands for its tech-savvy residents. Together, they spent about four years –  not counting the two years of interruption caused by the COVID-19 pandemic – working on the world’s longest bicycle, a metal behemoth that needs at least two riders.
