Do you know how a fixed speed bike works?

If it's a true fixie there won't be a flywheel on the rear wheel and the second you stop pedalling the rear wheel stops. He looks to be doing ~20mph on that video and the force of momentum on your knees if you instantly stopped turning the crank wouldn't leave you with healthy knees for long.

Not saying that's what occurred here but could explain why he keeps "pedalling".

Exactly, far better to plough into the side of a bus.

But why not use the other brakes, both can't have snapped? Why use a fixie in busy town traffic in the first place, they aren't exactly the safest mode of transport?

The bike originally had no brakes at all, and was only slowed by the rider trying to pedal backwards against the back wheel's forward momentum. There is no freewheel in the back hub. All the time the back wheel is turning his legs are 'pedalling'.
The rider fitted a front brake himself, for 'emergency' braking. That brake failed.

Why would you ride that bicycle at speed then? Or at all? My very first bicycle at the age of 3 was a fixed thing. I knew it was st back then.

At last we have someone to blame!
It's definitely the fault of the manufacturer of the after-market front brake system!

I rode a fixed wheeled bike with only a front brake (perfectly legal then) for years when I was a skinny schoolboy weighing 9st. With toe clips and shoe plates I could easily lock the rear wheel by resisting the turning of the pedals even on a dry road. He may well have broken his cable - either then or at another time - but he could have made some effort to slow by using his leg muscles. How successfully I couldn't say unless I was the rider.

How can a bike like that be legal to use on public roads? It certainly isn't safe for anyone.

I think the rider was the bigger danger here.

A very lucky cyclist, had he jumped the lights one-two seconds earlier he would now be spread across the road underneath the front of the bus. He is lucky the bus had advanced enough to put its side wall firmly into his trajectory.

As the cyclist was hurtling towards his doom with the speed of an unladen swallow the bus selflessly leapt into the fore and allowed it's delicate frame to act as a soft cushion to save that poor soul!

Good news all round!

This one has a much more interesting outcome. No personal best for them on the way to work that day.

That looked like it could be a quite nasty outcome; hope it wasn't as bad as it looked.

A bike as described above is not legal to use on public roads in many western countries.
The cyclist in the video is lucky to get away with minor injuries after jumping the red light. If he rode a bike that was not fit for use on public roads, he should face the law before he continues and possibly injures third parties.

As somebody who's more often than not a motorist, but frequently a pedestrian and sometimes a cyclist, it seems to me that the driving equivalent of a cyclist using that sort of equipment doesn't bear thinking about. When I'm pedalling two wheels the primary thought in my mind is how squishy the human body is. It wouldn't matter to me if a traffic light was showing green...if I had to be ready to stop in order not to hit some other vehicle that had ignored a red light, then I would be ready and stop! Being squishy is more relevant to cycling on the road than being in the right according to traffic signals. In this case the cyclist was in the wrong on that score as well which doesn't help.

Sorry if he did get hurt, but he has nobody to blame but himself!
