Best way to sell vintage pushbikes and encyclopaedias?

Local gumtree, and just stick to your prices, though it is very frustrating when you’re selling something for 100 pounds and get enquiries galore askIng if you’ll take 20 pounds or swap for Xbox 😔

Other than that I can’t really think of anything other than a specialist forum or local rag

The bikes I was hoping to find a specialist forum?
Encyclopedias are Britanica from 1883 leather bound look fantastic but as you say some what obsolete

Local library or perhaps some school might want it for teaching purposes?
I've given tons of stuff to schools in the past, most stuff I can't sell within a reasonable time-scale I just donate to local schools.
They have limited funding and are usually more then welcome to accept.
Bonus points for doing something back for the community!

for the bikes:
A lot of stuff seems to be getting sold through facebook these days. Always worth a try since it's free!

Thanks for the ideas

Bottom line is, if you already know what they are worth then you can advertise them all over the place, it really doesn't matter. If you don't know what they are worth you will have to auction them and I'm afraid that means eBay.

You can use eBay to find values if you shill bid stuff with a second account. I'm sure some dogooder will pop up on here acting horrified but really it's a good way to find the value without having to pay any fees. (The sale can be cancelled afterwards)

There's some pretty dubious advice on here already but that's basically what it comes down to.

Do have a lot of what the bikes are please
Especially the early ones

I never managed to find a good pushbike forum, facebook is ok but every tom dick and harry will message, gumtree is ok, ebay is a pain imo :-) encyclopedias though ebay might be better, as they draw a wider target audience. Specialist bookshops maybe too? What pushbikes are they anyway! :-)
