To take a bike on the maximum height (with me because of the high ceiling that's a piece) is sufficient in the pulley effect only as straight up. Beser to pull with one hand on the rope with the other hand to push the bike up a little is.
I have nothing to complain about, only the 10 screws and plugs that are provided, are not enough. Unless you have concrete floors, then it might go. I have used all the holes on the ceiling brackets and the bracket are per 10 pieces, so you have them ready again 10 screws / wall plugs that are not supplied with, not even the screws / wall plugs (2 pcs.) For the unroll mechanism.
