Mr Sanz has spent the majority of his adult life travelling the world, creating and exploring new sports and promoting energy conservation.

His latest import to hit Australia is a combination of a skateboard and roller skates.

``It takes about 15 to 20 minutes for people to master how to use the boards,'' Sanz said. ``What we want to do is get the population hooked on it.''

The small devices have an aluminium body and have two-wheels for each foot. A sideways stance similar to riding a skateboard is needed to manoeuvre.

A beginner would use a four-wheel ripstick while the most advanced person would ride the tiny freeline skate.

Mr Sanz hopes to incorporate a range of sports with the skates including skocca a version of soccer, hockey and basketball.

``These sports are going absolutely crazy overseas,'' Mr Sanz said. ``No real sports these days encourage families to play together. Instead of telling your parents you are going to the beach to go surfing, they can say `No, let's all go to the beach and let's do a bit of surfing, skating and kiting'. People are driving around in their cars and they are getting bored.''

Mr Sanz said the freeline skates could reach a speed of up to 90kmh and had the luxury of being able to fit into your pocket when you were not riding them.

``You slide on the side like a snowboard to stop,'' he said.

``A lot of people have had bad experiences with skateboards and they see this and think it is like a skateboard and don't want to try it because they may hurt themselves.

``With any sport you need to have safety precautions but we've found that we've had no accidents.

``When you are learning and playing on flat land injury is unlikely but if you are going downhill at 90kmh a hour you need full protection.''
