I had to enlarge the hole corresponding to the shock absorber bolt. And weld a transverse rod onto the upper part.

The backrest is of poor quality

Good, but could do better

The fastening system is very well designed, however the locking mechanism is inconvenient; it's located on the inside and at the bottom, requiring you to empty the bag to unlock it. A few internal compartments would have been welcome...

No

Arrived with damaged paint!

The assembly was complicated; there were no instructions. A shame.
