Attached to a Trek bike, it was mainly used for carrying luggage, not for children. Please note: Some parts are missing. The 5 sponge pads, 6 bent iron plates, and 6 black screws shown in the instruction manual image are missing. Also, a screwdriver is not included. Please be aware of this beforehand. Also, I have included images of the item in the cardboard box, and it will generally be shipped in this condition. I will include some cushioning material, but I will not take any waterproof measures. There are scratches, so please check the images.
