HELP! Can't install quick-release front wheel

I bought a Tern Verge Duo in Taiwan several years ago. During my most recent trip there, I decided to finally bring it back to the US. I took it to a Giant store to get it packed it and boxed, and in order to do so they had to remove the front wheel.

Prior to this, I had never removed or installed the front wheel before. So now I'm trying to install it and for the life of me I just can't get it! Every time I try to do it, the wheel locks up in the fork is prevented from spinning. But just looking at it, I don't see how it WOULDN'T lock up once you tighten the quick release? I put the wheel on and tighten the quick-release, that makes the fork clamp down on the wheel hub. And there are no bearings or anything between the hub and the fork, so of course it's going to lock it and prevent it from spinning.

I have included pics with arrows to illustrate what I mean. The arrows point to where the fork makes direct-contact with the hub, and if it's making direct contact then of course it's going to prevent it from spinning. If I loosen it to where there's no longer contact, then the wheel will wobble a little because there's a little pit of play when you stick the skewer into the hub. I have tried placing the springs on the outside of the fork and the inside of the fork, neither of which fixes the issue.

Am I missing something here?? Help!

Can't quite tell from the pix, but it doesn't look like the quick-release lever is fully locked. It should be perpendicular to the axle when in the locked position, or very close to perpendicular.

On any QR hub, the wheel should be slightly loose in the dropouts when first inserted with the QR lever in the loose position. Closing the QR lever gives the final bit of compression on the bearings.

You should be able to hold the ends of the axle in your hands and roll the tire on the ground to get it spinning. I suspect this test will fail and your hub needs to be repacked and adjusted.

Can you take some photos of both ends of the hub with the wheel off of the bike? Perhaps without the Quick Release.

I think this is your Kinetix hub.




It is hard to tell, but it almost looks like that uses some kind of end cap on the hub.

I'm seeing notes to these endcaps.

Or something similar, perhaps different widths for 74mm vs 100mm.

Anyway, that axle stub/end cap should fit into the hub before the quick release.

How tight is the quick release in the hub? Any play? Does the hole look like it is the right size?

The end caps of the hubs are missing, so the wheel won't spin if you tighten the skewer, because the fork is touching the hub body. The end caps (for dahon/tern/kinetix) are what transfer the loads from the fork to the bearings. They're a kind of axle. So technically, you're missing an axle. DO NOT ride the bike without the end caps, and DO NOT ride with a loose skewer. You're just going to damage the hub and the skewer if you do this, and will probably crash. You should try to find out where your end caps went and put them back on the hub.

Or you buy a new hub of the same model on AliExpress for $12 and swap the end caps. Or the link the person above has the caps for around $4 each. Or call Dahon or tern and ask them for replacement end caps. They both use this hub. If you look into the hub hole, if the bearing is labeled r4, then you have the new version. If it says 608 then it is the old version. The end caps are different for the 2 versions. The cap pictured above is the new one which is pressed in. The old version is threaded.

If you tried riding like this then you are putting all the load from the fork into the side of the skewer which is not what it is supposed to do. The load on the bearing races would also not be distributed well

I don't like the new hub though, with such thin axles on the end caps. I prefer hubs with a continuous axle.

OMG thanks guys I figured it out!

So when I first un-boxed it, the wheel came with these things attached to the hub. I thought they were just used to protect the wheel during travel.


I had a sneaking suspicion that the bottom one might be part of the puzzle. But it was capped off on the other side so there was no way to put the skewer through it.


But after reading your posts, I examined it more closely and realized that you could pull out the ends!


None of the numerous YouTube vids I watched before mentioned anything about endcaps. I knew I was missing something lol, I was like there's no way this could work like this as-is. Thanks for the help guys!

Oh, the smallest things can cause the biggest headaches!!!

And, bikes do evolve slowly.

I'm glad you got it working.

Well then. I have never seen a hub end-cap stick in a protector before! 🤷
