Today an amazing bicycle.
This machine was built in about 1920 by an African in Malawi (Nyasaland as it then was). What a brilliant craftsman!
He used natural materials throughout. The solid tyres were of ox-hide. The chain was made from knotted antelope skin. The frame and wheels consisted of wood, reeds and laths.
Probably the pedals were positioned in this unlikely configuration only for the taking of the photograph.
