Id be fine with it if not for one reason.

It has wheels.

Other than cogs and the occasional broken carriage i can not think of one item, mount or such that has wheels in eorzea. The caravans use ballons and float. Most mechanical things skip the wheel phase and go straight to flying. NPC's make fun of the idea of bicycles.

And to be honest, the model shown of the bike just looks unfinished and ugly. It is waaaay too shiny and smooth. If they roughed up the textures im sure id change my opinion.
