I ordered these a few months back, and never needed to use them! These are brand new, unopened, still wrapped in their packaging (see photos). If you need anymore photos please let me know. These Acedeck CNC Hub's are for the NYX Z3, and the Nomad N3 Electric Skateboards. Yes, each box has 1 Wheel Hub + 2 Bearings. I have a set of 4 for all 4 wheels. I prefer to sell them as a total package, but if you want 1 or 2 please message me and let me know. Typically a set of 4 would cost you $225 + shipping and taxes, I'm listing these at $175 for all 4, and I'll meet you. I have a few more on hand as well that are brand new, if you need more than 4 please let me know. Message me if you have any questions! We will need to meet at a local parking lot next to the police cameras just to keep everyone safe. Cash only please, and no trades.
