Shocking moment ‘hundreds’ of teen cyclists on charity bike ride cause traffic mayhem going through red lights and weaving through cars

THIS is the shocking moment hundreds of teens on a charity bike ride dangerously pedal through a red light the busy West End.

The young cyclists weaved in and out of traffic and popped wheelies as they caused traffic mayhem.

They were filmed by outraged cabbies as they raced through a red light while shoppers in busy Regent's Street were trying to cross.

The teenagers were wearing 'Ride for Sasha' t-shirts to spread awareness for cancer sufferer Sasha Williams.

The mum-of-two has reportedly been refused a bone marrow transplant and stem cell treatment for her leukaemia.

Hundreds of riders cycling on her behalf were filmed causing mayhem as they took to the streets of central London on October 22.

Shocking video shows the cyclists speeding through a pedestrian crossing as confused walkers jump out of the way.

They are then nearly struck by black cabs making their way across the road.

One cyclist barely manages to squeeze through a tiny gap as he narrowly avoids being hit by a car.

One cabbie posted the dashcam footage on YouTube with the caption: "London's junior cyclists running red light".
