Seen those before. There Auctally not beed locks at all. Instead what the person did is take the tire off, cut a circular plate out the outside size of the rim, and welded it goths tire. There's no added. Benifit or anything to do with it, but it just looks cool. So yea the rims are completely seperate from the circular rims. Just welded on. I've seen ppl do it on YouTube.
