A 36" - 40" muni would be good for those who like 2 speed downhills and through tight bends without a care in the world. Also a carbon fibre or kangaroo 36" would look tempting 4 me. Imagine what that would look like. Would it even be stable or even durable even though a carbon fibre giraffe exists.
Greek cypriot, eh?
The existing 36" wheels are quite good for this (with an airfoil rim, anyhow), although probably not quite so good in slick mud! (as my ankle found out recently)
Well, I imagine a Carbon Fibre frame could be made. Guess it might have some stiffness advantages… Ken Looi has been doing some work on a lightweight coker setup so maybe he’s considered it…
A kangaroo 36 would be INSANE 
I’d love to see one ridden - also, a 36" BC would rock. Somebody should try making one with an old BMX hub and an old steel rim - should be quite cheap if you’ve got the right contacts!
a 36" bc would probably scrape your balls if you rode it at all with your knees bent. i am planning/ going to try to build a carbon fiber frame so i will tell you if it works
what he should do is take the technology of his geared MUni’s he is creating and put it on his trials. that way you would have a trials and if you wanted to go faster for muni you could
I suggest reinforcing the CF frame w/ aluminum. I think pure CF would snap really really easy. then you would be left with 2 peices of a very expensive frame.
That’s right evan i’m a greek cypriot australian and mighty proud of it 
Here’s what a carbon fibre giraffe looks like:

Even this looks like fun:

So maybe a carbon fibre or kangaroo 36" could been done. Especially with advancements in technology 2day. Anything is possible.
I can’t believe that no-one has mentioned yet that 22" wheels do in fact exist. Miyata make a 22" unicycle. Josue Barretto rides one and can be seen on it in Universe 2. On the subject of odd wheel sizes, 14" and 18" unicycles also exist. The problem with all these unicycles is getting tyres (and to a lesser extent, tubes) for them.
It’s Ivan. So, do you live in Australia or Cyprus? Or somewhere else, maybe? Do you know any unicyclists in Cyprus?
I live in Oz ivan. Someday i like to go back home in cyprus. I have family there and let me just say it’s nice to meet another cypriot. I also apologise for spelling your name wrong. 
Ah, okay. Look me up if you go. We could unicycle together. I’m russian cypriot. No worries about the name.
ps. I live in Larnaca.
I’m thinking of coming next year. So yeah maybe i’ll see you then hahaha
I don’t believe so
Relax, if 22" is awesome, others were before Kris Holm was born.
Swalbe (AKA Swallow) still makes 3 different 22" tyres:
the HS 166 profile
in ETRTO 37-490
in undefined measurements: 22"x 1.3/8, 550x35a
art#: 11123070
and 2 versions of the HS 110 profile
in ETRTO 37-489
in undefined measurements: 22"x 1.3/8
art#: 11122060
So they are not very wide, and not nobby at all. But you’ve mentioned using it for freestyle as well.
I am confused as to why you would just think about fiddling with your crank lenght instead of recreating a new wheel size. Stick with a 20" or a 24" and try to alter your crank lenght and tire size to get the perfect match of styles. Tores and Cranks are cheap and easy to change.
Yup, 22" wheel unicycles have been around for years. Just not around here. Have fun replacing tires and rims! Because it is not a common bike size, it is unlikely to be pioneered for unicycles as the tires and rims would both be inordinately expensive. It’s already enough to pay for the smaller production runs on seats, seatposts, frames and hubs.
36" Kangaroo? Take a crank off and rotate it 90 degrees. Doesn’t cost a dime! Probably fun for an hour or so (or for a parade, but the audience probably won’t get any more out of it than a Kangaroo with normal sized wheel).
As for large BC wheels I haven’t seen any of those, but I have seen Tom Miller (The Unicycle Factory) ride a wagon wheel unicycle with the frame off; essentially a 46" ultimate wheel. Yes. Be careful! Severe crotch damage!
I’d like a 42" air tire unicycle, with something like a 1.5" tire (to keep the weight down but not ride too harsh).
Just out of interest, does anyone here know how much it might cost to get a 21" or 22" (KH 2007 standard quality) unicycle made, as a once off?
In terms of the feasibility of mass producing them, think about how unlikely the idea of a 2007 KH20 must’ve seemed to unicyclists 10 years ago! If there’s a big enough demand for 21"-22" trials wheels/tyres then it’s gonna happen. I wouldn’t be surprised if there’s also bike trials/street people who want the same thing.
Companies like Maxxis make tyres for all sorts of vehicles, from cars to lawn mowers. I don’t think that producing a new size tyre (that’s going to get sold) is going to put them out of pocket too much. Kris holm’s already been selling their stuff for years so all it would take would be for Kris or whoever to go along to the tyre manufacturer wth a print out of his sales figures and projections (and a copy of Defect) and strike up a deal.
If you want a private label tyre with your corporate logo as profile that’s expensive. Only the molding will cost $5,000. I know as recently I’ve been asking offers around.
But to answer your question: not much more than 24", like I showed, tyres are available (from stock!).
So rims must be out there as well. 22" is a size that was used by Schwinn. To find them now I would look in specialized low-rider/beach-cruiser bike-shops. And if you don’t find them still no big deal; custom size or not, you don’t order rims in small amounts. Rolling a rim into a odd size is no big deal for rim factories. So yes, they may ask a little more, but with firm negociating not; as there is no reason to ask more (and you will get at least the same amount of rims out a alloy extruded -unbended- profile! Very maybe even 1 more).
Then, if you order frames in Taiwan -like Kris does- they don’t mind different tube-size that much. Unless you order just 1 piece of course. However -depending on the frame construction type- you may need a welding molding (that again is costly).
Your question reminds me to many-times worldchampion Ot Pi of Monty, who is the cause 19" tyres and rims are “widely” available today. 15 years ago that was a more impossible size than 22".
the cost of a unicycle 22" will be fucking high!
just get a wheelset ride it with no tire that should get you the 22inch performance you want ( and youle crusify every joint below the hips and many above them too)
If you like obscure sizes; today I spoke with a manufacturer of 23" tyres.
