(finally, I can put that one random middle school hyperfixation I had to good use)
Okay, I could be very wrong and a part if me thinks that these specific types of wheels I'm about to show did show up in a different scene later in the season, but I think those wheels are supposed to look like a modified version of these ⬇️
Yes, they are vaguely square looking and are weird but their construction is specifically designed for an easier, smoother ride over "rougher" urban terrain (like you're not going to get bothered as much is you happen to hit small rocks)
Obviously you can put them on any board, but the intended audience is longboard users who live near shitty roads or something.
I mean, we can say they look like cherry blossoms till we're blue in the face, but I'm over hear thinking he had to go somewhere and hunt down a guy who could make usable off-road longboard wheels and had them custom shaped to be cherry blossoms.
Which leads me to wonder if Reki made them.
