Do you like flying down a path on a skateboard? Sure! But maybe you don't like having to push off all the time to make the thing go.

That's why the Pumgo is so neat. A Pumgo? What's a Pumgo?

Invented in Atlanta, Pumgo is a skateboard that you can keep going while keeping both feet on the board. And you don't need batteries --- or a motor.

While you're riding it, you rock your feet back and forth to ''pump'' the parts of the Pumgo that help turn the wheels.

Get it? Pumgo: ''Pump'' as you ''go.'' And the more you pump, the more you give your leg muscles a workout.

''Think of it as surfing on land,'' says Hui Yan, the research scientist with Emory University School of Medicine who invented the Pumgo. It took him years. He worked on it in his garage in his spare time and created about a dozen models.

Finally, the push-free skateboard was introduced at the 2004 Super Show in Orlando, Florida. Was it a hit? Yep! It was even named Sports Product of the Year.

News for Kids recently tracked down Yan and business partner Rob Howell in California, where they were working on promotions for Pumgo. Their company, Landsurf, expects Pumgo to be a hot item this holiday season.

Pumgos in red, blue or black likely will be for sale by late September. Look for them in sports stores, or get more information at www.pumgo.com.

Do they cost more than a regular skateboard? Yep --- $229. Recommended ages: 7 to 107.

To start, 20,000 to 50,000 Pumgos are being made in China, Howell says.

''Maybe in the future we can find a manufacturer in Georgia to help us create special editions of Pumgo,'' Yan says.

Ryan Atchison, 12, of Sandy Springs, already has a Pumgo. He was in Buckhead when the Pumgo team was showing how it works.

They also were giving away models, or ''prototypes,'' in a contest --- and Ryan was one of two winners.

So . . . does Ryan, a seventh-grader at Ridgeview Middle School, like it as much as his regular skateboard?

''I like the Pumgo more,'' he says. ''It's pretty cool and definitely more fun because it's easier to go fast --- and I like to go fast.''

He also likes the Pumgo's big wheels (almost 6 inches) and has been riding it a lot in his back yard and on everything from rough pavement to grass and sand.

But he doesn't expect to quit using his old skateboard. Why? It's ''for doing tricks and stuff,'' he says. ''The Pumgo is a lot heavier, so you can't do as many tricks. But you can do everything else.''

While he's been getting attention, Ryan's attitude has gotten pumped up. ''Ever since I got my Pumgo,'' he says, ''I've been more into skateboarding in general.''
