Even the name of this anime can summon one of the greatest openings of all time.

Ikki is a typical punk kid who gets into hundreds of scraps but after getting humiliated by a gang wearing a new form of skating gear known as air treks, his adopted sisters take pity on him and introduce him to the world of Air Treks and the very gang like world it has created; becoming entranced by the extreme skating craze, Ikki forms an air trek team with his friends and a couple of former rivals called Kogarasumaru as he aims to dismantle the establishment on his way to the top, completely unaware that Ikki's adopted sisters are part of a more legendary team known as Sleeping Forest.
The art style, the setup, the lore, they didn't need to go hard on it but hard they did and my god is it over complicated but still friggin awesome yet not much of the manga was covered in the anime.
I dabbled in skater culture in my teen years and I discovered Air Gear a little too late to really push that interest further, the aesthetic, that killer opening and some of the best urban art of display, it's a perfect canvas of the edgy 00s.
Dub was fine, prefer the sub.
Final Verdict: Finishing this series can be a chore but the experience is a good look into the early 2000s culture, there are very few other shows in any genre that could do the same.
