It's extremely easy to forget that Chad Kerley is only 18 years old when watching him perform on his BMX bike. After all, he's out there beating kids with 10 years more experience than him. However, there are still moments, and videos, that remind us Kerley is just now reaching the age that kids are graduating high school. We were poking around his Vimeo account and found this video that Kerley uploaded three years ago of him and a friend belting out "I Hate This Part" by the Pussycat Dolls. He hides nothing as he makes up some sweet choreography, as well. Watch him hilariously do his best Nicole Scherzinger impression above.
