My son is hard excited about this go-kart. I am actually satisfied - up on the seat. Which is fixed only by means of two plastic clamps on the rod. So you can seat although infinitely adjustable, but it wobbles a bit. Bin How long does this curious seat fixation, especially as the seat so has a kind of handle on which you can lift the kart and often also must. The assembly requires a bit of technical skill and an eye for the right screw. And through the wide profile tires the kart is even a little off-road capable.
