Selling Guide
Where to Sell
Facebook Marketplace, OfferUp, or Craigslist. Local pick-up platforms are best due to the high cost and complexity of shipping a complete bicycle.
Selling Tips
Clean the frame thoroughly and use steel wool with lubricant or rust converter to remove surface rust from the chain and bolts. Ensure tires hold air before listing. Use keywords like 'Diamondback', 'Commuter Bike', 'Hybrid Road Bike', and '7005 Aluminum'. Highlight local pickup availability.
