Well spotted, Klass Bil. Only after magnifying it did I see the wobble 
Reminds me of the âWorld of Gooâ game we played a few years back.

No one has said this so I will.
This film is a very nice production indeed. But the terrain is what I would comfortably do without getting out of the seat on my roadbike. He even rides on smooth gravel towards the beach but edits out before getting anywhere near the sand.
Whereâs the video of some downhill on a rock garden?
I donât think this is a wheel for off road. So how useful is this suspension?

Loopwheels says the 26" version will be released 2017 for MTB
https://www.loopwheels.com/products/mountain-bikes/
Question still is if it is possible to mount a unicycle hub to this wheel.
Up to now they say it is not possible to adjust the spring tension so we will have to wait and see if this is rideable at all.
Wow, thanks for posting this! I havenât been following the latest developments of this technology and wasnât aware you can just buy a 20" front wheel off the website now and itâs not too expensive. With a drum brake! I might have to order one to turn into a peg unicycle. Then in a couple years Iâll be ready to ride the 26" MTB version down ski trails in the Summer.
The pave, because pros wouldnât care about lost energyâŚ
Maybe the strade bianche
When do I get this for my uni? Itâs totally strong enough 
As I mentioned above, Iâm convinced it will be possible through the use of custom made flanges. The spring tension is likely to be an issue, but then for muni we tend to run very low tyre pressures and whilst we might have all our weight on one wheel we donât tend to hit things so hard, so it might just work. I also wonder whether spring tension can actually be adjusted through the use of custom flanges (clearly not something theyâre considering).
Iâm wishing I had a bit more spare cash, as actually Iâd be very tempted to have a play with a 20" wheel.
I actually went to put in an order for a 20" front wheel and Dahon front fork but there was an issue with their PayPal settings. Iâll complete my order when thatâs resolved. Shipping to the US is a bit steep (ÂŁ85, ÂŁ30 more than my geared drift trike front end which is certainly heavier). I have concerns over the axle size (3/8) but weâll see how it goes! Letâs see who makes the first loopwheels unicycle!
OK, thatâs finally ordered. Itâs got to go from the UK to the USA so thereâs still time for someone from Europe to beat me to the punch.
Youâre planning on using the wheel as it is for one of your unpowered freewheel devices (soory canât remember the correct names for any of them)? Or what else do you need the Dahon fork for?
I was looking at getting a rear wheel, as Iâm sure I read something about the spring tension being higher, and for my plans Iâd just be discarding the hub anyway - does mean youâre paying more for a bit you donât need though. Though I do wonder whether they might be prepared to just sell me the parts without a hub if I mention my plans - canât do any harm to ask.
My immediate plan is to turn it as-is into a peg unicycle by sticking pegs on the axle and a seat post and saddle in the fork. Iâm planning to use the Dahon fork since itâs known to work with the wheel and has the right inner/outer diameter. I realize the tension is lower than the rear wheel but itâs hard to tell which is better suited to my purpose. Itâs just a big experiment to get some experience with the technology before their MTB version comes out in a couple years. Iâll leave it to you and others to see how hard it is to put in a unicycle hub although Iâll be happy to share any information that I can. Judging from their feedback and Instragram:

I think they are amenable to custom orders.
Thereâs probably a reason BMX went to 14mm. On the upside, you should be able to pick up some pegs from the bargain bin at your LBS since they made 3/8 for decades. Also, depending on the drum brake you may be able to replace the axle with a CrMo axle from Wheels Manufacturing. That would probably put your worries to rest.
Ah, so I could still be the first with one in a conventional unicycle. To which end Iâve been doing a bit more research on their current products. I think youâre mistaken about that disk wheel being evidence of a custom order though - it appears to be a production prototype of the disk hub mentioned on https://www.loopwheels.com/products/trikes/ Almost certainly a front stub axle hub looking at that, which is presumably an adaption of their existing cast stub axle hubs used on their wheelchair wheels. Certainly no way that a cast hub is a custom job!
It doesnât seem likely theyâre going to phase out their adapters for conventional hubs though, as it would be prohibitive for them to make their own internal geared, or even cassette hubs (hence another reason that disc hub is a front). Nothing is going to be easy though - I checked the specs on the rear hubs theyâre using and even the 3 speed has assymetric flanges. I suspect I have enough info to start working on designs, but await your feedback with great interest.
When looking through their stuff I got quite excited by the wheelchair wheels as it turns out what they describe as 25" is actually what most of us call a 26" wheel - not sure if thatâs a wheelchair convention, or simply an attempt to obfuscate and stop people making the connection I did. Unfortunately it seems their wheelchair wheels are all using their cast hub which seems to have permanently attached springs so no obvious way of converting that.
Seems like itâs a wheelchair standard: Help with Tyre and Wheel Sizing - Draft Wheelchairs
It also seems itâs a similar sort of thing to 28" vs. 29" vs. 700c - all are the same rim diameter, and tyres should be pretty much interchangable (widths permitting) and yet there we are, with three different size measurements (28" is usually used to describe 700c tyres I think, to differentiate them from the slightly wider/taller 29er tyres) 
Wheel sizes are seriously weird even just in the bike world (I have a bike thatâs running 27x1.25 wheels, which despite the numbers is a slightly bigger diameter than a 29er/700c/28" rim thanks to metric vs. imperial measurements), Iâd imagine adding other vehicles just throws the confusion around even more.
Thanks for the update! Iâm not mechanically inclined (one time I busted a crank puller) but may need to take some classes so I can satisfy my own needs for unicycle ideas in the future. Besides their cast hub Iâm not sure if they only have one âcenterâ to attach the springs and hub or multiple ones. For instance, I canât quite tell if the specs of the Sturmey Archer X-FD (used on the commuter bike model) and Sturmey Archer X-SD (used on the recumbent trike model) are the same from looking at them. I sent an inquiry to LoopWheels to see if I can at least get my wheel changed from front wheel tension to rear wheel tension with a front hub. Iâll keep you updated and can give you measurements when I get the wheel.
Ultimate Wheel?
A LBS âexpertâ in unicycling has told me much that contradicts what I have read elsewhere. One of the things he said was that an âUltimate Wheelâ is a brand name, much like âFreonâ is for refrigerant or âKleenexâ is for tissue papers, and that the proper âindustry standardâ term is âPedal Wheelâ. Has anybody else heard of this? And, if so, why havenât I heard of it by now with all of my searching? I would really like to know if my local LBS unicycle expert is FOS or not.
In the 21 years since I first signed up to the unicycle mailing list (which was rendered obsolete by rec.sport.unicycling, which was then replaced by this forum), itâs not a claim that Iâve ever seen or heard before.
Iâve just had a quick flick through Jack Wileyâs âThe Ultimate Wheel Bookâ (published in 1988) and didnât see anything about it being a brand name. The closest I found to anything about manufacturers was at the beginning of chapter 3, where he wrote: âAt the present time, I do not know of any ultimate wheels that are manufactured.â
Unless John Foss pops up and says otherwise, Iâm going with FOS.
I found out they arenât offering the 20" disc wheel as an option at this time but it sounds like it will be at some point. They gave me the option of a 20" front wheel with 3 different spring forces.
1.) Normal: used in the bike front wheels,
2.) Medium: used in our trike front wheels,
3.) Heavy: used for heavy duty trailers.
I chose #3. They also said the hubs are not interchangeable once theyâre built. I believe that means they use different hub interfaces and I wonder if the force tuning is done with the hub in place. So in order to use a different hub (like a fixed unicycle hub) itâs probably necessary to develop a custom interface (with or without the loopwheels team) and then they would probably need to build and tune the wheel. Iâm waiting until after I get my wheel to see if itâs worth trying to take any further. I imagine it will take the release of the MTB wheel to garner enough interest from unicyclists to try to commission a custom interface (if thatâs even a possibility). Another option may be to replace the internal components of a hub that already has an interface with a direct-drive axle.
Ah, I thought Iâd already commented on this. Yes the interfaces (the triangular bits which bolt to the hub and hold the springs) must be different for each hub because the flanges are different on each hub they use (both different diameter and different offsets from the centre line).
I have to admit Iâd not considered the idea of a custom interface. My plan was to get some flanges made which bolted to a uni hub and provided holes in the same place as one of the hubs they use, so that you could just bolt the supplied interfaces on - something similar to what is described in this post: Aaaagh - broken flange on my Schlumpf - #14 by nickjb
Iâm sure it wouldnât be too hard to get something like that made - whilst a custom interface would be a better solution, it would involve a lot more complex machining. The remaining issue though is that the interfaces will be under preload when fitted to the hubs - I suspect they attach the springs last and have some mechanism to preload them when they fit them. Itâs not going to be straightforward to do without that.
Very interesting to hear that they will fit different weight springs though - that certainly solves one issue, as itâs a lot simpler to make something to front hub dimensions. I wonder if I supplied them with a hub with identical flange dimensions to that whether theyâd build one up for me? Looking forwards to your feedback.
It wasnât clear to me if the triangle was a single piece or if there was something that fit inside it for the hub to attach to but I think youâre right that the triangular bit is the interface and thereâs one for each type of (geometrically different) hub. I can give you details on the one that I get.
Yes, this is probably the simplest route. Itâs probably not something Iâm capable of doing. Iâm sure LanceB will share the files from his 36-48 Schlumpf adapter rings and maybe thatâs something I can work from. I have access to 3D modeling software but not necessarily the expertise to use it.
One of the key factors is whether or not the hub can be switched out without removing the springs first. If thatâs the case then thatâs a huge feature for me. I would love to have a single wheel and be able to swap in hubs (freewheel, fixed, peg).
Itâll probably be another couple weeks before I get the wheel but Iâll let you know how it goes.
