I observed from the video he went into a pothole then fell down. He's probably shocked when the bus hit or almost hit him.
i think its a road surface that they covered up recently
i see like he went over a bump...
but you could be right that its a pothole
they want everything to be perfect for their cycling
else they blame road, blame bus, blame weather or any other
Cyclist lucky to be alive becos bus kept to its lane and was travelling safely
lucky he can at least spend this x'mas with family
knowing that his pure road skill is sub par... throw face even
