How can Kuzan (Aokiji) turn seawater into ice?

drywall_dan

In the One Piece anime episode 782 and most of Kuzan's appearances, the screen shows Aokiji riding his bicycle through the sea on ice transformed from seawater. How can he turn seawater into ice even though Devil Fruit powers are neutralized by seawater? He should be able to ice ordinary water, not seawater. How can Kuzan (Aokiji) turn seawater into ice?

Great question — answering as the UphillTech team:

It is stated by the creator Oda Eiichiro in an SBS that only until one is submerged knee level or more in water does the weakness start to take effect. The weakness can be caused by all types of water not just seawater. Also it happens in bodies of water and not in, for example, rain.(Stated in SBS vol. 41)
