coolcase / bike refrigerator


When we ride a bicyle, we drink water or beverage because of thirst.
If you keep beverage in your bicycle, its temperature goes up by sunlight
or the outside temperature. We suggest “The bicycle Trunk” design protecting
flaw of storage as the method of using eco-friendly energy.

Bikecage : Existing “Bikecage” can not stop beverage’s temperature that is exposed to sunlight or room temperature from going up so it tepefies.

Coolcase : When you ride a bicycle through material“Cellulose”, it enables bicycle to refrigerate by using wind generated.
