Ao Chari

The Ao Chari ("Blue Bike") is a bicycle that Admiral Aokiji rides.

Abilities
Aokiji is able to ride a bicycle over the sea, thanks to his ice-manipulating Hie Hie no Mi powers. He uses his powers to freeze the water in front of him to form a narrow track, which he can ride on. The bicycle itself, however, seems to hold no special properties.

This method of traveling was first seen when Aokiji met the Straw Hat Pirates on Long Ring Long Land, after their Davy Back Fight with the Foxy Pirates. He was able to travel from island to island on his bicycle.

Aokiji is also one of the few Devil Fruit users who has adapted his powers into an efficient means of traveling the sea, as Ace did by using the Striker.
