Roboriders

Hello. I am currently collecting golden Roborider wheels, once included in combo packs of Roborider sets sold in Germany, as pictured below: I know Roboriders is only tangentially related to Bionicle, but I figured this forum would be my best bet at finding any for sale. Please PM me with any offers. For those interested in trading, I have three of the Axer mold (pictured above) and am willing to trade up to two of them for any golden wheels other than Toxic or Stunner.
