Does Doug's bike qualify for this trope, or is it "merely" a Flying Motorcycle?

[Bob Schroeck]

Actually, it does. The wheels are on cantilevers and when Doug wants maximum power they swing up (one to the left, the other to the right) and expose thrusters/emitters/whatever you want to call them.

Why it does that is honestly Rule of Cool, both in-universe and out. (Skuld and Megumi went a little overboard.) But yeah, it qualifies.

Thanks. Added to the trope page...
