This is the shocking moment more than 40 cyclists ride through a red light in barely 20 seconds.

Pedestrians are crossing the road when the first group of cyclists flash past.
Many are doing wheelies as they ride through the set of lights in Regent Street.
The footage was captured from a black cab's dashboard camera and appears to have been filmed two weeks ago.
It was uploaded to YouTube with the description "Please welcome the next generation of London cyclists... if they survive that long" and has been viewed more than 120,000 times.
As the lights turn green, more cyclists ride past dodging vehicles, with one squeezing narrowly between two black cabs.
