Taking part in the London leg of the World Naked Bike Ride, the bicyclists bared all as they cycled by landmarks like Piccadilly Circus and Big Ben.
The bicyclists of any ages triggered from six different points throughout the city before assembling at Wellington Arch by Hyde Park Corner.
Some got innovative with the birthday-suit dress code, embellishing themselves in paint.
Though relatively pointless at face-value, there is a major message behind the nudity, which is indicated to reveal the vulnerability of cyclists on roadways.
The occasion, which has occurred in London from the year 2004, also protests humankind’s reliance on cars.
Individuals at in 2012’s protest were asked to keep their packs on until before the demonstration was due because of the fears any unintended nudity would distress relations with the Metropolitan Police.
A statement on the demonstration’s website read: “Do not undress until just before the protest moves off, as this will undermine our positive relationship with the authorities.”
Statement continued: “There is no law against nudity in Britain, but please don’t exercise your right to nudity in London before the ride, as it will impact on our ability to make arrangements with police.”
