I don't think they're slippery at all from what I've read. It is epoxy after all. It might have a high shine, but it's super durable. I was going to suggest this as I read Knolly's post, but ThatKid beat me to it.^ While it looks fantastic, I'm not so sure I'd want a slippery surface when handling bikes. And I can imagine it's fairly difficult to locate a loose nut or screw, ect on these multi-colored floors, lol.
