I had a similar issue that eventually resulted in my finally eliminating the stem wobble problem (actually, my scooter would not fold, at all) by first disassembling and fully removing the entire folding mechanism and then carefully reinstalling it (by suggestion from VoroMotors), taking particular notice during the reinstallation to how far down the barrel nut needed to be threaded onto the latch bolt (the one that lifts when you fold the scooter). Once it (the barrel nut) was threaded far enough down the bolt and the adjacent nut secured tightly up against it (while being careful to not thread the barrel nut too far down the bolt) the scooter finally would properly fold and unfold again without any stem wobble. Yay! In my case, though, unfortunately, using manual hex wrenches to turn those very robust bolts that keep the folding latch mounted to the scooter, in such a tight space, resulted in the friction from the turning bolts causing severe scuffing and abrasion to the outer sheaths of the wrapped wiring bundle, which resulted in the internal wires becoming exposed; a very bad outcome, to say the least! So, essentially, I fixed one problem but created another, more severe problem. Ugh. Not realizing the extent of the damage I caused to the wires that protrude from the front of the battery deck, I tested the scooter for functionality while it was still elevated on its repair stand after the latch reinstallation job seemed to be complete. That’s when the nightmare truly began. I’m not a mechanic and this is my first electric scooter. My DIY skills generally suck. The throttle and LCD seemed to perform as it should. Then, I squeezed the rear brake lever and POP! I blew the transformer or step-down controller and now the scooter was suddenly rendered inoperable. It could not be ridden. I knew I had just screwed up big time. Then, I tested the lights and another loud POP as they came on briefly and immediately shut off. I felt like such an idiot. This was about two months ago. I had to ship the scooter from Georgia back to California for a full diagnostic and repair. But, because I received the scooter brand new six months prior and had put 550 miles on it, I no longer had the shipping box, which meant that I had to wait for a new one to be shipped to me. Then, logistical issues with the shipping label, pickup arrangements by UPS, the ordeal with boxing it up securely again, the 6-day commute across the country, the anticipated repair delays due to a work-order backlog and claimed staffing shortage, the Christmas and New Year holiday, and unknown costs involved (a few hundred bucks) and finally the return trip back to me and still I await its final arrival next week. I wouldn’t wish this crap on anyone. Lots of lessons were learned. I’m excited to ride again. Peace ✌🏼
Man, it sounds like you've had a tough time with this thing. I'm assuming you accidentally damaged the cables when dealing with those front mud guards, and that they probably shorted out when they touched the metal frame after the scooter was turned on. I made sure to try and push the wrapped cables back in the space between the mount and held it with one hand as I was reinstalling so they wouldn't be clamped against. I've ridden a good 15 miles since and no pops or other messed up parts, though I did change out a couple of the hex screws on the front mud guards for longer ones as a personal preference. Also wanted to mention that just in case you see that kind of damage ever again with your cables, wrap them with it electrical tape before turning anything back on (assuming you didn't actually cut the wires themselves but just left bits exposed through the insulation) Right before filming this video, I disassembled the locking mechanism and then reassembled it. My problem isn't the barrel nut or the locking nut, but the two silver screws holding the locking mechanism to the frame. They unscrew on their own when the latch is moved, causing the stem wobble to return if they arent tightened again each time. At Voro's suggestion, I'll be applying loctite to those bolts this weekend and seeing if that fixes the issue. I'd really like to be able to ride and fold it down after without having to constantly tighten up those bolts. Though by the sound of things, I guess I should consider myself lucky I can even ride it the way it is! Anyway, sucks you had to go through all of that to get yours working again, but I'll bet it's gonna be fun for you to hop back on it. Hope things go better for you the 2nd time around!
Thanks for the video I was wondering where the movement was coming from on my scooter and looks like you have the answer, I'm going to try to tighten the side screws and since I have mine locked down (no folding unfolding) hopefully it will feel more secure, Thanks!
I can see from affar that is not that bolt that is loose, it is the nut behind the lock pin, the one that you have the chain and the rubber on it... You need to give it a round tight, see if it stops, if it dont, give one more round... Do this until it stops wobbling... When you press down the folding latch, you should have pressure, no like that ez to lock down...
Thank you for your concern, the issue has long since been fixed. What you said is not correct, however. The problem was actually a defect or design flaw with the entire latching mechanism. Two bolts holding it from either side can never be tightened properly, or the latching mechanism won't open or close, but if you leave them loose you end up with the problem in the video. There was no 'just right' with mine and tightening or loosening the barrel nut doesn't change this. Unfortunately, at least with the one I received anyway, the only way to safely ride is to loctite those bolts and never unfold or fold the scooter again. Also, if you don't have loctite etc, you can use 2 zip ties to place in between the stem and the locking mechanism to prevent the wobble as a temporary fix
I don't know what you're talking about. The scooter is designed to be able to fold and unfold without this issue. The company acknowledged it wasn't normal when I contacted them about it. It has since been fixed with some loctite on the bolts you see in the video.

No problem, I'm happy I could help. I put some loctite on them before tightening and that seemed to do the trick.

Usted mismo lo dise de ahí biene el problema x estar desplegando y plegando

Pero cual es la necesidad de estar plegando y desplegando este aparato lo cual creería q es x eso su problema

Was on the main highway at like 55 mph and got speed wobble 😂😂😂 terrible feeling and i hope this works, im gonna try it now
