A friend of mine volunteers time at a bike charity. It is a real charity, donations to them get a tax deduction in USA. They accept donated bikes and parts, they fix them up and sell them. Disadvantaged kids get discounts to buy them. They also hire local kids and try to help teach them a skill (bike shop mechanics and retail experience). Occasionally they get some really nice stuff and price it appropriately to hang in a window. I donated a bike, a new frame that I changed my mind on and decided not to use, several other parts, etc. I also bought some parts from them a year ago when I bought a new rando bike frame and built it up.
There was another volunteer at that charity that recently died. He did not want his beautiful Litespeed Ti bike to go to a stranger so he gave it to that friend of mine that also volunteers time to them.
Option three, find a consignment seller that sells stuff on Ebay and gives your estate a percentage of the sale. Write up the description that goes with each item since consignment sellers are clueless on a lot of the stuff people give them to sell. Then tell whomever that does your estate that the bikes and bike stuff should go to that Ebay seller for consignment sale.
