Aaron “Wheelz” Fotheringham is an 19-year-old wheelchair athlete from Las Vegas, according to his website. Aaron was born with Spina Bifida, a birth defect of the spinal cord. For Aaron this means his legs don’t work. But his daring certainly does.

After training in skate parks for years, he has earned titles at BMX freestyle competitions for his wheelchair stunts which include backflips. He's performing upcoming at the Nitro Circus; one of his rehearsals was captured below.
