wow, that is crammed in there!. Do you have a close up of that "quick release" crate?

Here is how I did it on my folder bike. I didnt think it looked to sturdy at first, but I have had no problems with a 20lbs. backpack full of school books. Of course I am not bombing of curbs and what not on the folder either. I will get a pick of the rope attachment on my MTB's crate next time I have it on there.
