Speaking for mine only, yes, I find it near perfect - as in Goldilocks. I really don't want this beast moving on its own in a stiff breeze, say, or someone careless (like me) bumping into it and it bump into something else.
So there is just enough friction in the six casters that I can use a booted foot to shove first one end a bit, and then the other end a bit, and so on. I can also get hold of the fall-over bars and move the whole thing, careful to work down low so as to not upset the bike.
