The drone hits a tree, and flies into the guy's wheel. Then over the handlebars he goes.
The video was from another cyclist, Kaito Clark, who was also in the Golden State Race in Sacramento this weekend.
Clark says the drone operator offered to buy a replacement helmet (which broke,) and wheel, (also broken.)
I have a feeling the biker is going to want a little more compensation.
He also had a pretty severe case of road rash. Luckily, he didn't break any bones...
