I was cycling through New Cross. There was a cyclist in front of me overtaking a slow moving bendy bus on his left. I was at the rear of said bendy bus and about to attempt the same manoeuvre. To the cyclists right was a flat bed truck.
There was not a great deal of space for the guy to squeeze through. As he came level with the bus he started to turn in. As he did this his bike clipped the truck and all I saw was the rear wheel flying in the air and a crunching sound. The bus stopped and as I came level I saw the bike firmly trapped under the front of the bus.
Luckily the guy was unharmed apart from a nasty graze on his elbow. I checked if he was okay as did several pedestrians and helped him to pull the bike from the bus. He was so lucky not to have been seriously injured.
