The rear-extension for compact electric cars (seen in the photos and videos on a smart fortwo EV) serves the purpose of acting like a 'backpack on wheels,' giving your eco-friendly form of transportation extra storage room. The demo photos and video seen here are meant to show off the flexibility and versatility of the Swiss design, as it can be used for purposes such as pizza delivery, DJ stand, skiing, camping, etc. It also features a range-extending battery pack give you some extra mobility while out on your environmentally-friendly jaunt.
