This is the bone-crunching moment a cyclist crashed into a car and was sent flying over its roof before smashing on to the road and writhing in agony.

The cyclist, whose Twitter name is BrokenLegs, posted shocking GoPro footage of his collision on the site.

It shows him cycling at speed in a London bike lane when a Volkswagen polo slowly turns into his path at a T-junction.

The cyclist smashes into the side of the car and is hurled into the road.

His helmet camera captured his bike spinning in the air as he landed on the tarmac with a thud.

He lay sprawled on the ground as horrified bystanders asked if he was OK.

The cyclist claimed the driver didn't stop to check on him but zoomed off.

He wrote on Twitter alongside the video: 'If anyone can help to identify the number plate of this hit and run on me, so I can inform the police, please let me know.'

Disputes between cyclists and drivers have become increasingly public in recent months as bikers record their journeys and post their crashes on social media.

Footage recently emerged of an angry row that erupted after a cyclist and car collided when the driver tried to make a right turn.

The cyclist, who recorded the incident on his helmet camera, can be heard to shout 'Woah Jesus!' as the red Toyota Prius turns towards him on a road in north London.

After the collision, a pedestrian walking past shouts: 'Oi, that's your fault. That's your fault.

'You shouldn't be overtaking on the inside like that, and you know that.'

The cyclist responds 'He's got wing mirrors', before the onlooker says: 'Don't take the p***'.

The cyclist continues: 'What happens if motorbike comes down, it's the same thing. Is the motorbike allowed to take the outside?

He adds: 'I'm riding on the right as much as someone else.'

In August a woman was arrested after BBC presenter Jeremy Vine posted shocking footage online showing a road rage driver threatening him in the road.

The Radio 2 host filmed a woman unleashing abuse after he cycled in front of her car on a narrow street in Kensington, west London.

Father-of-two Mr Vine, 51, later uploaded the video on his Facebook page, where it has since been viewed more than 500,000 times.
