Edit after interaction with their support team:First, thanks Amazon, I got a free replacement. But it had all the same problems. But then, with help from the vendor support , I was able to work through understanding my issues.Long story short, besides the inaccurate setup docs, none of my original issues are actually problems using the scooter.The “play” in steering doesn’t present itself during actual use. The resistance to steering goes away after a little use, they just have the head tube torced pretty tight.And the rubbing with the disc brake goes away after a little use. I’m sure I could adjust it away completely, but not a big dealI think they suffer from some “first impression” issue they need to work on, but this is actually a quality piece of scouter engineering.First impressions were not great. The instructions for assembly don’t match the state of the scooter when it is shipped. Instructions show handlebar attached and it’s not. And there is no info on how to do that. But at least that you can figure out with some googling.Of more importance were three defects, two in assembly and one is design.The front steering is very stiff and not at all smooth. At first I could barely rotate it by hand. It kind of “grinds” as if the bearings aren’t smooth or perhaps the steerer tube is tightened too much.The other is there is significant left/right “play” in the front steering, apparently introduced by the front suspension assembly. I see a good 1/4 inch of play each direction holding the handbags still. I haven’t tried riding at any speed with this, but it seems that could introduce dangerous wobble at speed.Finally, out of the box, the rear disc brake rubs against the break pads, significantly increasing rolling resistance. It didn’t look warped, but something is causing contact at some parts of the rotation. I might be able to make adjustments for that, but that ought to be done at the factory, before shipping. This is not like wholesale bicycle that will go through setup at the retail store before use.And the bad news, all this was not a one off. I immediately ordered a replacement which arrived quickly (thanks Amazon) and had exactly the problems, in fact worse with the brake rubbing. I didn’t even finished unboxing that one, since it was worse than the original.Now I have to decide to put up with it or return it and go through the research all over again for a higher quality adult scooter. What a waste of time.
