If you guys are looking for an image of an Air Treck, here it is fresh from the manga.
Although that wont help you much. But at least you get the idea.
Anyway, I saw someone at youtube to actually make a pair of skates similar to an Air Treck's appearance.
Although it doesn't have the motor you guys are looking for.
Here's the video of it.

Now if you guys are wondering... "Does it run well?"
Well... yes. I saw the test run as well.
Here's the video.

Well... I have to say this, but you cant grind with those.
But I just had to give you guys the idea that the "design" or "appearance" of an Air Treck is possible.
And here's how he made it.

Now if you guys got the idea.
If the batter power, breaks, wheels and other problems are solved.
And you have successfully created "Air Trecks".
Good lord. Contact me. And I'm buying one. :D
