How much do I ask for my son's bike when selling.

[steven1988]

August 2015 we bought our eldest a Cuda energy 20 inch wheel MTB he used it for 3 weeks before getting an Isla. After 2 years of it standing dorment I want to sell it but don't know what I should ask for it.

I can't find ant completed listings on EBay as I guide

Ask for 60 quid, or nearest offer. Accept 50 'for cash'.
