Hi,
Another suggestion you may be able to get him to test the waters on. Pick the best looking 3 or 4 that have “forged” or integrated derailleur hangers on them. The Raleigh Racing, Schwinn SS, Nishiki Mixte, Gitane, etc. Clean them up, put air in the tires and list on Craig’s List for $125 the next weekend with decent weather. Plan to meet potential buyers at a local park where they can test ride. Boxes of parts & any partially assembled bikes should probably be donated to a local co-op or bike kitchen. If this works just keep repeating. It will take a little effort, but will most likely give you the best results. If something doesn’t sell lower the price for the next weekend. Donate any leftovers.
Good luck,
Senior Ryder 00
