OnRoad x Unload / luggage

Using luggage is risky carrying bacteria on the wheels back to houses. To solve this problem, OnRoad x Unload is the combination of a trunk and removable bottom. The bottom is a wheel carrier for outdoor using, which can be separated by the following process: 1. put down the pedal that attached to the bottom, 2. step on the pedal, and 3. detach the bottom from the main trunk. There are totally two sets of wheels for different places, not only the bottom part for outdoors, but the main trunk has basic wheels for indoor carrying. The concept of OnRoad x Unload is like leaving dirty shoes outside the house and only take clean part back home.
