Problem solved, I forgot the shop-tick in the theme-options.

Unfortunately me.

I did some research.
In the unicorn-theme within woocommerce it is sidebar-5, in other pages the sidebar has the id “sidebar-6”.
Within the Biker-theme sidebar-6 is shown, but sidebar-5 is not created.

I see now this is standard WordPress.
I’ve got the answer.

Sorry
