If you've had a drink, don't watch this video.
When the king of BMX tricks Tim Knoll left his skateboard at his local skate park, he thought it would be too easy to walk down and collect it.
Instead, equipped with his bike and GoPro camera, Knoll filmed his ride down to the park in Milwaukee and threw in a few original freestyle tricks for good measure.
Watch and be amazed, but don't blame us if your head is spinning afterwards.
