So yeah, i am looking for a little support with this one. I am trying to get into riding a unicycle and i need to know if there is one to support my weight. I weigh 152 kg or about 335 lbs. I know that is alot but 6’2" and a power-lifter kinda makes you heavy. I have pretty good balance, stilt walking is one of my favorite hobbies, so i just need a uni suggestion.
Thank you.
There are plenty of unicycles out there that will support your weight but they are going to cost a bit more than other people’s learners.
You are going to want splined cranks (ISIS or otherwise) double walled rim, at least 36 spokes, and a seatpost at least 25.4mm diameter.
Most people seem to learn on 20" wheels but I believe that taller people would learn faster with a slightly bigger wheel (like a 24").
Any quality trials unicycle should hold up for learning to ride if you want a 20" wheel, or if you want to try a 24" pretty much any decent mountain unicycle (MUni) should work well as well, but I would consider swapping out the knobby tire with something smoother until you have the basics down.
A popular choice for a very strong budget unicycle is getting a Nimbus trials or MUni and switching the venture cranks for KH Moments. If Qu-Ax is popular in your area that would also be a very good choice.
There’s some good explanation here: http://www.unicyclist.com/forums/showthread.php?t=90925
You might ask the guy who started that thread, BrickMan, what he ended up buying. I think he’s built about like you, and he’s posted some videos of himself hopping around on rocks and stuff. It looks like he has a muni with a 24" wheel. I can’t tell the brand though…
I would say look for a good price on a 24 muni
In general, all the major brand muni 24’s are strong. Maybe made for a guy half your size, but that guy was gonna drop down pretty far. Until you start to drop down half that distance, physics is on your side and any of the major splined muni 24’s would be a good choice. Spring extra $ for the KH free ride seat upgrade if you can.
Get a 26in nimbus MUni with moments and you will be set. Also LOVE the DKM song name. alouse looking for chicks over 400 pounds!!!
Thank everyone.
Hey, i really appreciate all the comments and the help. I have asked this question before on some other sites and the most frequent response was “Loose some weight fatty”. I’m so glad that this community is what it is. I will definitely be referring all of my friends here for questions. 
In short i should be looking at 24" trail Nimbus or Munis ? btw my inseam is 33"
It depends a bit on your goals.
bigger than a 24 is gona be kind of hard to learn on.
If it were me, since my main interst is Muni, I’d get a trials to learn and fool around on at home. Then get a 24 or 26" Muni. A 24 is better in tech terrain and easier on the hills, and a 26 rolls a little better, better tire selection and a bit faster.
If cruising is more you, I’d get a basic strong 24 like the Nimbus II and save up for a 29 or 36.
There was a guy near me (I think he was 320) who learned on a 24" Torker DX, and Hookworm tire (and lost 15 lbs. in the process). Unfortunately I think he lost interest after learning the basics and I lost touch w/ him.
we are all pretty friendly here until you get into whether or not people should wear helmets, which crank length is best, or which rugby team is going to win the world cup 
Just to clarify things a bit:
When we say trials unicycle we are referring to a small sturdy unicycle designed for hopping and jumping. They will have a 20(19)“x2.5 or 2.6” tire splined cranks, strong wide rim and sturdy components.
When we say MUni (or Muni) we simply mean a Mountain Unicycle. There is more variety here with 24, 26, and 29" sizes available. Like trials unicycles they are designed to take a beating.
Bigger wheels will go faster pedal smoother and roll over obstacles easier but are harder to control. For learning I would not suggest getting anything larger than a 24.
skilewis74 also gives good advice and I forgot about the Nimbus II. It is not a MUni but definitely fits the criteria for a good strong learner at a smaller price point. The cranks aren’t the strongest but I see that an upgrade to 150mm KH moments is only +$31 on the US Unicycle.com. Moments are a bit overkill for learning but can’t hurt to have the strongest cranks ever made, and you can transfer them to another unicycle later if you want.
You don’t even need the splined axle (ISIS) unless you plan to jump around on it. Just get one of the beefier ones and you’ll be fine, especially for learning the basics.
We don’t have to say it. If you learn to ride it’s going to happen whether you want it or not. 
yah higher end square taper stuff would work but “high end square taper” is sort of obsolete. I started with square taper cranks and at a little over half his weight it didn’t take long before I was wrecking cranks.
He is a big guy and a powerlifter, (Sorry spicy mchaggis, I am generalizing here) think of the stress cycles he is going to put the hub and cranks through even if he doesn’t jump. I sure didn’t just put my weight in the seat and spin smoothly when I was learning.
I hate riding something I am worried about breaking and if I were him I would worry about braking a LX or Club. Get fancier than that and you might as well get a uni with an ISIS hub.
A Nimbus II (20 or 24) would be an ideal learner for not a whole lot more than what we usually steer people towards. A MUni or trials would be great for the long run if that is the kind of riding he is/gets interested in.
I learnt on a KH 24" MUni with big knobbly tyre and it didn’t appear to slow my progress (I was ridding unaided in a a few hours and ridding offroad in a few weeks), I am only 5’9" so I would definitely go for a 24" at your height. As has been said MUnis’ are built tough to survive people doing stupid drops, straight gauge spokes wide double wall rims, ISIS cranks etc you really won’t break one riding normally.
The Nimbus II 24" MUni is what I almost went for (before going mad on a KH :p) and would be suitable for your needs as a learner and for many years after that.
It is one of the most fun and rewarding things you will ever do 
I have to confess I thought that once … and then the guy happened to be a very agile and much better unicyclist than me ! :o !! yet another prejudice I had to throw away! welcome aboard!
If putting more weight onto the saddle makes the Uni more stable surely the heavier someone is the better 
I know when I go over soft squishy mud I feel I could do with some more weight to aid traction
I believe I gained weight after taking unicycling back up. Granted my legs used to be jello and now there’s some muscle in there.
I inadvertently found this thread that has a similar discussion
http://www.unicyclist.com/forums/showthread.php?t=59810&highlight=percussion
I usually agree with John
Everyone here knows he knows more than I do about uni stuff. Here, I will depart, and say you, as a fat ass heavy guy, should go ISIS splined crank uni only. Nimbus 24 muni is fine and easy to get. Koxx 1, and KH are light and strong, but more $, pretty much just to shave 2 lbs off the uni, they are not stronger. Nimbus, Torker DX , Qu-ax, splined 24’s are usually cheaper to buy, and just as strong. Shop, deals happen. You want an ISIS splined 24 muni from the major brands and a KH free ride seat. We fat guys love that seat !
Yeah a lot of Nimbus’ used to come w/ the UDC cotterless hub which was pretty strong (for cotterless), but you were still restricted to cotterless cranks. Now I think all of the Nimbus’ are all ISIS.
There are cranks that are a bit stronger than that on the LX or Club, but not by that much.
So I would definately go for anything splined (now mostly ISIS) more for the cranks than the hub, and if you plan on doing anything rough on it or a lot of hopping, make sure they are strong. ie for ISIS: KH Moments, Qu-Ax Chromolly, or Onza Tensiles (in order of strenght most to least).
One more thing.
First, thanks to everyone again for all of the help and suggestions. Now i think that I have found three unis that are in my price range (right now) and fit the descriptions i was given. Sun 24" Flat Top Street Unicycle, Hoppley 24" Unicycle, Torker Unistar CX 24" Unicycle, so should i get one of these if so which one or should i save a bit and get something nicer? I will be riding alot on a gravel roads, concrete, asphalt, and hard dirt mostly learning on the gravel.

They all have the same flimsy looking cranks. Still should do for learning.
Should they break/bend, I think Nimbus Venture Cranks are available for cotterless axles, so this is mendable. But they’re a serious price upgrade so I wouldn’t buy them before the original turns out too weak.
