S-I-B / Solarpropelled IcecreamBicycle


The energy autarkic Icecream-Bicycle (I-B) generates electricity through an installed solar panel, which serves at the same
time as a shelter against sun and rain for the peddler. The solar energy will be utilized for a conventional refrigerators, which
can be shelved via a fold-out baffle to the loading area of the I-B.

Instead of refrigerators, other items, e.g. crates for drinks and so on, may be installed. Thus the bicycle can be flexibly used for
various purposes.

With an extra seat located in the loading area, the bicycle can even be used as rickshaw.
