I'd chop it up like this: there's the love of bikes, then there is the love of stuff.
I love bikes and riding, and different bikes do different things (in function and in quality) and expanding the collection hopefully expands my ability to love and enjoy it.
But I don't like having stuff I don't need although I probably buy all kinds of shit I don't need all the time because that's modern life innit. I'm not a minimalist twat or anything like that but I do try and only have few nice things and try to keep the rest of my crap in functional rotation.
So when I get tempted by the new hotness or something flash I always ask myself: "Am I chasing my love of bikes or my love of 'stuff'?"
tl;dr: I have one bike and that's enough to make me happy.
