@Funkeydunk The thing is that you have done these upgrades to suit you and to fit your idea of the perfect bike, or at least the ideal one for you. But it won't fit anyone else's ideal unless you are really lucky. Sadly a bike is more than the sum of its parts, unless you take the drastic step of selling the parts separately.
I prepared for the sale of my Focus Jam2 by removing the shiny new shock that has been fitted only a few months before and refitted the old one. I sold the TEC pack separately and sold the shock separately too. I sold those two items for a good price each and I sold the bike for the same price that it would have sold if I had included them in the first place. I am confident about that after talking to the bike buyer.
So, by any chance can you convert your bike back to its basic spec? Is that a possibility? When people look at websites, they do comparison shopping and see
that particular 2019 Levo is this much, as is
that one, but that
other one is 40% more! No way!!
In my opinion, extras become freebies. Sadly, they only add value while you are using them. They will make your bike sell faster though, but you seldom if ever get a better price that will reflect the money you spent.
This is depressing and I share your pain. Selling a bike is like selling a child (almost).
