I don't think you can really bring "crock n doles" and cacktivators into this, as they are only mtb type bikes.
From experience toss bikes include (no doubt this will upset a few people):
Any Y bike
Any Marin with a brake roller stem; any marin FS that is overly complicated, but still essentially a single pivot, however + points do go to Marin for their unbelievably strong matt paint.
Any E stay bike made out of steel or Ti (merlin inc).
Anything made out of "russian military" Ti...
Any FS bike that you're constantly fixing play in the @rse end, no matter how good they ride.
Anything that requires U brakes.
"Cheap" Aluminum...
Anything ever to come out of Winsconsin
Anything that used the public to do product testing to see if it worked...
kona 2*9- what the fudge???
Now I've pretty much slated every design ever built or thought of, i'm off for a spin on my e stay saracen with my buddy on his 1991 karakoram....looks a little muddy out there...
