Unbike.
For me it would be called a Death Machine
Nah, Iām sure youād figure it out quicker than I could. Itās way ahead of my abilities right now, but the last parts I needed got here so I built it up and itāll be ready when I am.
It certainly canāt be as bad as a BC wheel. Mounting it is easy with the wheel in the grass where it canāt roll. You can hold it up with the bar (a decapitated 300mm x 22.2 steel seatpost actually) and step on one foot at a time. And the bar seems to works well enough as a seat, so wheel walking should be like on a standard unicycle except without the spinning cranks. Thatās supposing I ever learn how to wheel walk!
Is this intended to be a variation on a bc wheel to be ridden or is it purely aesthetic?
Edit: I see we posted at the same time, never mind
Do you have details on how you did this? It looks great! Iāve been wanting something similar except with a saddle instead on handle bars and a disc brake.
Meant to be ridden or attempted at least. Inspired by this video and this discussion, and also from watching videos of flatland bmx riders who rarely touched any part of the bike besides the bars and the front pegs.
So yeah, purely aesthetic pretty much.
Thanks! Thereās nothing more to it than what you see: 1.5" 48-hole bmx rim on a Suzue front hub with 14mm axle, standard Diamondback pegs, a closeout bmx fork from eBay, basic bmx stem, slightly dinged spare Sun unicycle seatpost, and Wal-Mart grips. To mount a saddle, I guess youād want to slot the top of the fork and clamp a seatpost in. (25.4 mm I think, but I could measure if you wanted to know for sure.)
Thanks for the info! Iām not sure where the Sun unicycle seatpost comes in. It also seems like bicycle forks usually have a lip at the top and I wonder if in addition to cutting a slot that this lip needs to be cut off, too. The plan I have for doing something like this is to have a unicycle seat, disc brakes, and BC plates (instead of pegs).
The Sun unicycle seatpostāwith the bracket hacksawed offāis the handlebar! It just happened to be the right diameter and it seemed as likely a shape as any, not knowing any better. Not necessarily my final choiceā¦
There are different fork steerer configurations out there, esp threaded vs. threadless, but this one doesnāt have any noticeable lip to it. Anyway cutting a steerer to suit the frame and rider is normal and super easy. But one of the things I liked about this fork was that the steerer is pretty long (200 mm) and hasnāt been cut.
I noticed that a 20" BC wheel just showed up in the Trading Post btw. It would have been cheaper and easier to start with that if it had been there a month ago.
Got any idea on how youāll do the disk brake? Not that you shouldnāt, but you seem to lose the easy connections to the BMX world with that.
Cool. For what Iām imagining I would just buy a peg-style drift trike front end with a disc brake. I already have BC plates I could put on it so I would just need to have the notch cut and put in a seat post and seat post clamp. However, this is not my immediate next project so I probably wonāt do anything about it until after Unicon.
Itās starting to take shape.
I just need to bind the uprights into the proper position, and place the slots (stacked on left) under each wheel with the wooden blocks as stoppers behind the wheels. I might swap out the line on top of each one for velcro instead. This would allow me to flip the shorter uniās up so their neck and saddle is out of the way.
A couple freewheel projects Iām working on
Iām working on a couple freewheel projects I thought Iād mention here in case anyone has feedback or constructive criticism.

Hi waaaalrus,
you havenāt seen any 24" Conundrum used to the full because until recently, there was no 24x4.0 tires available (Surly dropped the Endomorph 24x4.0 and all the subsequent fat tires).
It is the On-One baby fatty announcement that revived the 24" world and gave the hope to 24" Conundrum owners to to over 24x3.0 
Anyway, I canāt wait to see pics of your projects
P.S.: worst case scenario, you still can run maggies on your Conundrum of disc braking doesnāt work the way you expectā¦ 
Yes, it seems the Baby Fatty was delayed a bit but I found it in the wild recently. That one has the Vee Rubber Mission tire but the 24x4" On-One Floater is supposed to come out in the next couple months. Thanks for reminding me about maggies! They donāt give me a sufficient braking environment on my 36" freewheel and I expect the result to be the same on the Conundrum but itās certainly worth a try. On my 26" freewheel unicycle I currently have a 160mm rotor mounted on a DāBrake. On steep, paved descents I have to be careful of my speed because I can go faster than I can control easily with the brake. When Iām getting to that point I have to yank extra hard on the brake in pulses instead of the continuous modulation I prefer. I want to compare my current setup in that scenario against a 203mm rotor mounted on a steel disc tab (and a 160mm rotor mounted on a steel disc tab if that ends up being too much). I run sintered disc pads so can drop down to semi-metallic, too.
DIY Muni tire cleaner.
I was thinking a backdoor boot-scrubber would do the job, but the farm-store wanted $35 for one. So I sacrificed 2 old scrub brushes and made my own.
Use heavy scrap lumber, stand back, and watch out for the flying spiked pedals!
Maybe I could give it a cheesy name like āThe Marriage Saverā and make a million dollars.
Waaalrus: I have a Devist8or I shrunk to 24x4 and it is a brilliant size. I generally donāt like 24" wheels but with that much rubber it just makes sense to downsize the rim (sort of like our ā19"ā trials wheels)
I think itās about time for the baby-fat revolution. 
EDIT: Congrats on your 768th post!
Thanks! Since I busted my 24" freewheel Iāve been riding my 26" and think Iām used to the difference now although it has a narrower rim (35mm vs. 42mm). The extra height was really noticeable at first and itās taken time to get the maneuvering down. My reversible frame is in the mail and Iām really curious to hop back on the 24" to see what it feels like. I like to take small steps so a fat 24" seems like a great configuration to try next. Iām bringing the parts to the bike shop this afternoon.
Waaalrus, I just sent you a PM.
The specs turned out slightly different from what I planned. I got a 24" Nimbus muni frame and the disc tab is sized 160mm on the normal side and 180mm on the reverse side. Iām using an adapter to run a 203mm rotor on the normal side. I presume thereās a 160 to 180 adapter that I could have used as well and avoided the disc tab on the reverse side altogether. I found that the 203mm rotor together with semi-metallic disc pads was a little too grabby at the low end. I switched back to sintered pads and the combination seems like a winner for me, not too grabby but plenty of power for steep or long descents.
