Hide sidebar items (pages) on some specific pages.

I am looking for a plugin that is able to hide certain links/pages in the sidebar when I am at a specific page.

I have searched and found several good plugins that are able to hide pages. But when you hide a page(link) in the sidebar, its hidden on every page.

Example: when I am at http://www.example.com/cars I want to hide all bicycle links(to pages) in the sidebar.
But when I am at: http://www.example.com/bicycles I want to hide all car links(to pages) in the sidebar.

I haven’t found this yet. I hope such a plugin/way exists.
