Biker gets beamed in the head while riding next to flatbed

A biker gets beamed in the head while riding alongside a flatbed trailer in this surprising video. 

In the clip, a biker is recording himself on a motorcycle when he pulls up alongside a flatbed hauling some construction equipment. Everything seems to be going well until you notice the roof of the machine starting to come loose in the background. 

The roof eventually blows off in the wind and the biker gets beamed in the head. He manages to keep the bike upright, but it seemed like a pretty serious blow. 

“How is motorcycle dude still on that bike??” commented one viewer.  

“The roof of that tractor is probably just a glassfiber shell, so it’s very light. Also, the guy is wearing a helmet. This is why they wear helmets. (Among other reasons),” commented another.
