Thanks for the replies. Very much appreciated.
Hey, Andyb1. Yeah, I am up in Dundee. I can pack it up if it need be. Thanks for that info regarding the prices. I gave the chain a good clean, but there are little scuffs and wear around the frame and seat.
Thanks for the kind words, in4; I'll pass them on

Is that the same number as the one I posted in my photos, or is there another one I've missed? I did get in touch with SJS initially and you're right about them buying for a %.
I was offered £400 to begin with, but when they found out it was an Alfine hub they weren't interested. Apparently the bike is worth in the region of £50 - £100, but I was told from someone on Facebook that it's still worth a lot more.
Tbh, I really have no idea what price I should be aiming for.
