More than a thousand cyclists swarmed through Bermondsey on Saturday, obstructing roads and heading in the direction of the Houses of Parliament.
Organised by Bike Life TV, the so-called #BikeStormz, encouraged bike enthusiasts to gather in large numbers and cycle through the streets of London.
Eva Charrington, 51, an eye-witness who has been cycling for twenty years, said: “I think the cyclists themselves don’t think about what’s happening. I think people are OK with it when it happens but it is just extremely dangerous.
“People were cycling along in swarms and one came up behind me and told me to get out of the way. They started going the wrong way up main roads. It’s ridiculous really. The police had to be called for everyone’s safety. It was anarchy.

“I called the police later on to say what I saw. I think it gives cyclists a bad name. Later on two thousand came bombing through Bermondsey. I know they were just little kids having fun but after these incidents I think cyclists have to be licensed.
“Something has to be done. I actually think the parents don’t know what they are up to. They were all quite young. I am sure their parents would like to know what they’re up to. I think it’s just a case of them being young and not knowing.”
Transport for London tweeted on the day that the ‘”cyclist demo” was heading along Tooley Street and Jamaica Road in the afternoon.
A TfL spokesperson said that police had told them around 1,200 cyclists were taking part in the event, with a few even going into the Blackwall Tunnel briefly.
The police were contacted for more information but a spokesperson said none was available.
Bike Life TV were approached for comment.
