'Pink Helmet Posse': Six-Year-Old Girls Taking Skateboarding World By Storm

They look like little Barbies on boards – a trio of super-cute, super-daring, super-pink six-year-old skateboarders from California.

The girls, known as the 'Pink Helmet Posse' have wowed fans across the States with their amazing flips and stuns.

And now Relz Murphy, Sierra Kerr and Bella Kenworthy they have won the admiration of skateboarding experts.

"They're incredible," said Jamie Owens, editor of Transworld Skateboarding Magazine.

"I've seen a handful of teenage girls in the park, but never girls this young. They're the real deal.

"I have daughters myself, and I was so pumped when I saw this footage and sent it to my wife, because our girls are just getting bit by the skate bug, and this will put them over the top."

Bella shared some of her favorite aspects of skating with website Girl is NOT a 4 Letter Word. She said she's been skating for 'a little over a year' and her favourite tricks include carves and grinds.

The girls' dads taught their daughters to skateboard when they were toddlers.

Sierra's dad Josh, a surfer, said: "By five, she was riding alone, which was pretty cute and fun then.

"Now, though, there's no stopping her. it's freaking me out. She's dropping into 11-foot bowls. There are grown men who've been skating for years who won't do that."

The girls soon welcomed their nickname, the Pink Helmet Posse, and got their parents to let them launch an official skateboard line for young girls.

They also launched a series of skateboarding video tutorials.

"We know it can be intimidating, but we're here to show you that skateboarding is not just for boys," their website reads.

"Come skate with us. You don't have to have a pink helmet, but we think it looks pretty cute."
