Camper Bike is a functioning sculptural piece, built in April 2008 by Kevin Cyr. There's also the Camper Kart, a pop-up camper constructed out of a shopping cart that "investigates habitats and housing; recycling and ecology; exploration and mobility." That works, I suppose. 
I want one.
Amazing, thanks for sharing
I would like to have such a Camper bike. Everyone should!
this is indeed a very cool idea and we are seriously developing something along this line. Be sure to check out our web site at:

We have two bicycle mini camper designs in the works and we are currently working on trying to raise funds through our IndieGoGo campaign to make the first prototype. Help us out and we can make this dream a reality:
