In keeping with the bike rack G6 929 I bought the loading dock to spare my back (A herniated disc is sufficient.). The joy that the bike carrier has the necessary slots for the hook. The first time driving on the ramp with my bike I was sadly disappointed: The loading dock slip faster than the wheel is charged. I hope that the wheel then you get charged more with practice. The first attempt was as I said disappointing. When unloading, the loading ramp has been adopted at the first touch. Here you have over a small edge to get to the track. Here you move quickly the lightweight aluminum piece. Had my bike with 18-19kg not so hard, I would put the rail shelved and simply lift up and down. Here I'm going to have to think so little to fix the ramp secure the support.
My conclusion: The idea is great, but their money (40, -Euro) not really worth.
