The UCI BMX World Championships year cancelled due to Covid-19 was 2020.
The championship was scheduled for Houston, Texas, but the COVID-19 pandemic disrupted the international sporting calendar and forced its cancellation. The event returned in 2021 in Arnhem, Netherlands, followed by Nantes in 2022.
This cancellation created a gap in the championship sequence: the 2019 edition was held in Heusden-Zolder, Belgium, and the next completed edition was in 2021. That is why 2020 appears in the historical table without a host result, rather than as a normal championship year.
The UCI BMX World Championships are distinct from the annual UCI BMX Racing World Cup, which is a separate series. The World Championships award rainbow jerseys and world titles, while the World Cup determines season standings across multiple rounds.
