Talk about some bad luck and timing.  This guy is just minding his own business riding his bike in the African wilderness and BAM gets taken out by this buck.  Seriously, this is crazy.  First of all it's a pretty wide open area so the buck really didn't have any business around the riders.  He could have been protecting or maybe freaked out by the noise.  Either way it's still extremely odd that this happened. 

Just like when Randy Johnson played for the Arizona Diamondbacks and the ball hit a bird traveling 95 mph on the way to home plate.  The odds of that happening are pretty much impossible.  The bike rider should have purchased a lottery ticket after this.
