An Indian professor, D P Mishra, rides it everyday to work, it has a horn that sounds like a flute, and it is made largely from bamboo! Yup, it's a bamboo bike he has invented to make bicycles more affordable and to reduce pollution.
"You cannot travel the path until you have become the path."— Buddha
Look at the picture of the bamboo bicycle. Email a note of appreciation to Dr. Mishra: mishra@iitk.ac.in
