The Streiberg - formerly Eichberg - is about 40 meters above the neighboring Linowsee. One does not have a view due to the trees, however, the "summit" with some boulders was transformed into a place of power.
Above all, you need strength to be able to do the 40 meters by bike. It goes down so much faster and the brake system should be fine.
Stones and signs with runes or similar symbol-like signs can be seen on the Streitberg and the paths to it. There is also a stone with a Sator square de.m.wikipedia.org/wiki/Sator-Quadrat. The way from the south is very sandy. There are well-navigable, so far not marked paths from the north.
