The carrier attachment is not included in the image. (Please purchase separately.) Offered at a bargain price. The color in the image is provided. Please measure the length and purchase bolts at a home center (length unknown due to rear fender modification). Hex bolts are recommended for easier work. The advantage is an increase in maximum load capacity from 3kg to 8kg. The disadvantage is a step difference with the seat (designed specifically for a box). Initially, I also used the original, but I changed it because the load capacity increased.
