Game Over Cycles, the Polish company which specializes in the construction of custom motorcycles and vintage cars restoration, has announced a collaboration with the country’s veteran extreme metallersBEHEMOTH.

Behemoth Bike, as the project is initially called, is a custom motorcycle inspired by and currently being created in collaboration with BEHEMOTH, and particularly the band’s leader, Adam “Nergal” Darski. The bike is planned by the designers to be a powerful dark machine with exceptional technical parameters and unprecedented ornamentation.

Construction started in January 2013. Completion of construction is scheduled for May, with plans to unveil the bike during the Impact Festival on June 4 in Lotnisko, Warsaw, Poland.
