here what Tilmann wrote me:

Hello Nicolas,
the Kickstand I have has been designed for Koga Bikes
and is only available with Koga bikes. It is not available
on the market. Have a nice trip in Africa.
It is a nice place to cycle I have been in Africa for 5 years
and have had very bad experiences. Holdups and Revolutions,
but I still like the place very much. People are fantastic.
Have fun and thanks for visiting my homepage
