Lehman B is a "do-tank" (which I assume is a think-tank with tools) "based on the belief that the best way to explore and embrace the opportunities the future holds is by living them and doing them." This bike-as-camper, called Supertramp, "explores the practicality of microsized living and downshifting as urban "flowmads" (another clever invention) take to the streets."
Designboom describes it:
It is made with a rigid frame and cloth tent façade and roof. One side of the home open up like a window and has a ledge, while the other side features a door. Inside the home there is a small wood burning fire with a chimney and a bed. the home was hand built and can be pedalled form location to location. the intent of the unit is to explore more minimal lifestyles that [may] be become a necessity in the future.
While the canvas enclosure is certainly light and easier to pedal, it doesn't provide a great deal of shelter or security, and putting a stove in a canvas structure is just a bad idea; I lost a childhood friend that way.
