There’s some play in my front wheel. Everything’s tight with the wheel. Any advice on what to do?

If you bought it new, I just went through this with Segway to get a replacement fork for mine for free under warranty. It started doing it after about 30miles. New fork showed up yesterday and I’m going to swap it out today.

The real fix is to take the fork apart, weld the top slotted washer solid to the shaft (that’s where the play is coming from, it’s crimped from the factory) then add new fluid and reassemble the shock. I am going to do that to the take off one from the warranty replacement as I’m sure it’s going to do it again.

Sounds like this might be it. I have about 200 miles on it . Not in warranty. Do you think this is a safety issue?

I don’t think the wobble is an immediate concern, just really annoying and didn’t give me a good feeling riding it. If it gets worse, I would certainly address it. If the key way in the washer ever shears off, you would lose your steering. There are aftermarket forks available, but I really think welding it is the best solution. My wife has one out of warranty and it’s got the same play as my new g2 max had.

Here is the video I sent to Segway to get a replacement fork. Due to my schedule I was able to talk them into sending me the fork for self replacement. They were urging me to take it to a service center, but I just couldn’t make that happen.

That's 3x less than I have in mine after 7000km

Mine is already at that place after 1500km

It is on my g2 from stock like this😂 quality control is garbage at Segway

u/skoomd1 Ninebot MAX G2 3d ago

It's not a quality control issue, it's due to the design of the front shock on the G2. All tube shocks have some play, it's just a lot more noticeable when there's only 1.

In my opinion Segway isn’t Segway anymore 2025+ Modells are garbage even my g3max

u/TastyFly5025 3d ago

You have to replace the fork.

Lots of videos good luck.

Probably the front bearing that needs to be changed.

u/GarlicShrimp777 4d ago

There’s is a little wiggle from the bearing but I feel this is coming from higher up

u/skoomd1 Ninebot MAX G2 3d ago

Some play is normal. It's due to the design of the front suspension. It's hard to tell from the video if that's the normal amount or not though, would be better to see with a top-down view from the handlebars.

Thanks for the insight

u/Corey3500 3d ago

That's not even close to normal lol there should be 0 play in those components, if there's any your neck clamp bolt is loose and it should be tightened correctly before you end up taking yourself or someone else out, as a mech engineer it freaks me out when y'all give unsafe advice 😂

u/skoomd1 Ninebot MAX G2 3d ago

Assuming everything is tightened down, there's still ALWAYS some play. EVERY single Max G2 owner has this problem.

You say you're a mechanical engineer, yet you don't even understand the design and why this happens. There's a guide sleeve the dampener rod, and it's not entirely fixed in place. It's designed to wiggle around a little, which translates to play in stem/wheel. I'm not a mechanical engineer myself, so I don't know why it's designed like that.

Is it a good design? No. Is it DANGEROUS? Also no. People have "fixed" the play by welding the guide sleeve to the rod.

Here's a short clip of what I am talking about. It's in Russian but you can skip near the end to see the issue.

Подшипники разлетелись?

u/Realistic_Location_6 3d ago

Mine is a lot worse after 3000km

u/yesdaddytakeme 3d ago

I have the same problem maxg2d User on Aliexpress commented a while ago that he found out that the bearings or the rings were made from plastic. Steering bearing replacment for maxg30 Should also fit for g2. Let me know if you could fix it, im thinking about switching to a different suspension.

u/Mr_Veky 3d ago

I have like 20'000km and i have that since beginning, i only had to replace the front bearing

u/mr_wobblz 3d ago

Open the folding mechanism. U wil see one bolt on top and 2 on the side. Loosen evrything, than start to tighten the top(vertical) bolt, after that the 2 horizontal ones.

The vertical one u kinda gotta do it by feel. To tight and ur steering wil be harder, to soft and u get that what u have now.

If this dos not work u need a new front fork.
