Aaron Baker is taking his three-wheeled bike out to a trail in California to do some downhill mountain biking. He and his friend are handling the turns and jumps with ease, when suddenly Aaron's three-wheeled bike collapses beneath him. The mishap sends Aaron falling to the ground, but it's nothing he can't handle! He's actually a former pro motocross athlete, and he's also a quadriplegic due to a spinal cord injury that he sustained years ago. As you can see, even though he's paralyzed, he's still way more active than many able-bodied people!
