A letter from Peter McBurney:
I recall your posts about the wirefrrame toys made by children in Southern Africa. I just came across this photo (which I’ve been unable to find online).
These bikes do not look like they can actually ued for human trasport, since the main body pole (the horizintal pole) would seem inadequate. I am not sure if they are steerable – the surrounding structures on the vertical pole look like they would permit steering, but perhaps this structure is cosmetic.

Making a toy bike like that requires quite a developed geometric thinking. Remarkably that such skills can be developed and pass from generation to generation in children’s subculture, without participation of adults.
