This year's Naked Bike Ride teams up with campaign Extinction Rebellion to spread the word about climate change.
Brighton Naked Bike Ride organisers said this year the ride will form a colourful and noisy procession through Brighton and Hove on Sunday, June 9.
It comes after Extinction Rebellion has staged a series of actions around the country, including the recent sit-down protests in central London.
Locally, activists have held a mass "die-in" in Churchill Square and a fete-themed protest outside Barclays Bank against their investment in fossil fuels.
Brighton Naked Bike Ride is supporting the group in calling on the Government to take action on climate change.
Ride organiser Duncan Blinkhorn said: "Moving to a future that is safe from climate chaos requires us to make better use of the Earth's limited resources, and stop pumping carbon into the atmosphere. World Naked Bike Ride demonstrates that less can be more: less consumption, less pollution, less clothes even! With just bikes and body power, we are campaigning for better road safety, a more stable climate, cleaner air and... more fun!"
Alice Doyle from Extinction Rebellion Brighton, said: "We're not just campaigning about the extinction of global animal and plant species, but about the potential extinction of human beings due to man-made pollution and climate change. We are part of nature, and thus equally vulnerable to the environmental crisis we have caused. We're joining this ride, and supporting the event, as a powerful symbol of both our vulnerability to pollution and our power to change it."
Up to 1,000 riders are expected to take part in the event on Sunday June 9, which starts from 11am at Preston Park, Brighton.
Participants will decorate their bikes and bodies before the ride heads off at 1.30pm.
Accompanied by a fleet of sound systems, the ride will travel along the seafront via Brighton Palace Pier, back down Western Road, through the Lanes, North Laine and Kemptown, before finishing at Black Rock naturist beach.
