This one is a real gem. The German company YT Bikes had the audacity to actually use rune writing stumbles in their marketing, which was stolen from Nordic culture by Nazi Germans to help fuel and inspire their rise which resulted in the death of over 6 million Jews. Truly despicable, but revealing for a German business to use these symbols.

The others are similar to rune writing, leaving little doubt as to what is referenced here.
No good reason for a bicycle brand to be engaging in this, especially a German brand, and especially when combining it here with the Nordic style artwork.
