COLUMBIA, MIssouri - They call themselves "Wonder Wheels," traveling the world turning heads with BMX bikes.

These stunt artists call concrete their canvas.

"We'll spend night alone in a parking lot or parking garage or wherever we're at practicing and you'll actually have people roll up and watch you for hours. They'll sit there in a car and just watch you," said BMX rider Bill Nitschke. "We're doing things that no one's ever done on a BMX bike before."
For this demonstration, they landed at Rock Bridge Elementary.

"You hit the jump and the ground just drops away. And you're like 'man I'm pretty high.' And you see the landing like floating like 20 feet away and you're like 'man that's pretty. far am I going to make that?" said Brian Strieby, another BMX stunt artist.

Added Nitschke, "There are still millions of people who have never seen this and they are blown away."
