Extraordinary bust-up sees London cab driver push a cyclist – only for his shorts to FALL DOWN

An irate taxi driver furious at a cyclist who kicked his vehicle leapt out of the car to push his tormentor off his bike – only to have to beat a hasty retreat when his pants fell down.

In the video the heavily-built cabbie runs across the street to launch himself at the bearded cyclist on the other side of the road, hurling him off the bike and onto the pavement.

But even as his victim is airborne, the taxi driver suffers a catastrophic wardrobe malfunction and his blue shorts slip from his waist – revealing he seems not to be wearing any underwear.

The altercation between cabbie and cyclist was posted to Twitter by a woman who described it as her ‘highlight of London’. 

Twitter user @Yorkshire_G posted a succession of follow-up videos which purport to show the moments before and after the ungainly fight.

In one the cyclist comes up alongside the driver’s side of the vehicle, with a cycling mask over his face, and according to the videographer ‘punched the taxi twice’.

Then, according to the Twitter account, the man ‘cycled the wrong way up the bus lane then looked for a fight. 

‘After circling the taxi in traffic and hurling abuse at the driver and us, he punched the window by my Mum and kicked the taxi.’

She described the ensuing altercation as a ‘quick scrap’ in which no-one was injured. 

After passing in front of the stationary cab the cyclist rode back down the other side of the road – but the driver leapt out, ran across the street and launched himself at the rider

And the cabbie was just readjusting his garments when the altercation continued 

As the videos unfold the cyclist and the driver can be seen exchanging words as the rider holds his cycling mask up over his face and glances between the driver and his passengers.

Then the cyclist comes past the cabbie on the passenger side, close to the pavement.

As he passes the front door delivers a hard kick to the side of the vehicle.

After some angry gesticulation the pair grab and shove each other in what the passenger described on Twitter as a ‘quick scrap’

The rider circles around the front of the cab, which is stuck in stationary traffic, and heads back down the other side of the street.

So the driver leaps out of his car and runs across the street, barely slowing before making contact with the cyclist with both hands, sending him flying backwards.

But in his outrage the driver loses his shorts and has to hastily grab them from around his knees before yanking them back up.

In a later video the angry cyclist runs back over to the cab and kicks the door, which the cabbie has positioned between himself and the angry rider. 

The pair can then be seen pushing and shoving at each other in what the Twitter user who posted the video described as ‘Quick scrap and no one badly injured’.
