True words in another way of looking at Unicorn bikes, whilst still learning what would work for me in my teens, I worked and saved a whole year to order a new Marin Bear valley se when I was 16. Good bike, very capable I now realise a bit too comfy and neutral for what I was like at the time.. But truly a dream come true initially..Nice thread!
For me unicorns are the bikes you enjoying riding the most. They don't have to be necessarily linked to what you lusted back in the day.
I am sure it happened to many of us, you lust for a specific bike only to get it and after riding it, be hugely disappointed from it (whether because of size, bike specs, not the right geometry, etc.).
I think it also helps if you are curious about a technology a bike has that you believe sets it apart from the rest (for me these have been Slingshots among others). Or you might enjoy riding a bike from the era just bc your favorite athlete was on it.
I believe eventually, I will end up keeping two or three bikes that I like and enjoy riding the most as I don't like to keep accumulating stuff that I can't properly use (last famous words... ).
( which is why I have my dads old Bear valley now with panniers and a flexstem for practical duties.. now I am older and boring..?!)
I also made the biggest mistake ever and swapped it after a year for a Cannondale v with headshox... looked amazing but what a total load of shite.. nothing but bother, and way too harsh so I swapped the frame for a Gt avalanche, which was fast etc more nimble but still a little harsh.
Then I bought a second hand kona kileaua for a commuter on skinny tyre's and that was me done with aluminium bikes for years, I found my perfect bike by accident almost, and I fell out of love with the Gt very quickly.
Until I got a whyte prst..! I now have my unicorn whyte, my third and last as its highday's and holidays only a mint prst 4 , thats the weird and iconic unicorn satisfied.. so it changes all the time I guess, I don't have the local friends and people you saw at the jumps spots etc but I still have peer comfort zone pushing me along, showing off many things I then desire by coming here!
