You may have seen bicycles in various interesting shapes, but the “Grasshopper” electric bike is the ultimate portable, user-friendly of them all. This zero pollution bicycle is made on composite materials to have  strength and rigidity. You can take this bike anywhere you want, fold it and take it to the trail or park.

“The  battery charges thru regenerative braking and thru stationary bicycling.” You can even convert this bike “into a stationary exercise bike” too ! David Goncalves is the designer and won the Merit Prize after presenting this design in the 2008 – 12th International Bicycle Design Competition.

Its a pity this is still a concept and yet to be in production.
