There is nothing to compare with, since this is my first scooter, maybe I got a defective copy, but after a couple of months I discovered that the welding seam in the upper part of the deck in front parted, gave it to the workshop, sealed it with argon, then another month of operation, and the metal is already torn straight over this seam . . apparently a weak point of the structure as a whole, I think to solve this by continuous penetration of the folding mechanism to the deck, additionally screwed a couple of reinforcing bolts into the plate, I am attaching a photo of the problem.
