I do a bit of CG so I decided to try making a unicycle. Tell me what you think 
Nice! that makes me want to try and learn how to do that for about the 5th time. What program did you use?
Truespace 6.6 for the modeling and bryce 5 for rendering 
Nice!
Could you post just the uni and not the background? Or how about a lighter background? It is really hard to see.
you forgot the seatpost clamp, the āalex dx32ā sticker on the rim, and the winged āPā stamped onto the hub. great model though, hats off to you.
Yeah, the background is a little busy. Itās like a patchy lawn with no horizon.
The unicycle is nice. I like the shiny chrome rim.
Yeah thatās pretty good, but Iād like to point out some things that would make it more realistic. Frameā¦ the forks need to be a bit thicker, they are VERY thin right now, would be scary to ride. The seat needs a bit of texture added to it. Add a seatpost clamp? Not really needed though. Deinately add some tred to the tire, thatās what tells you itās not real. And prolly change the pedals or add a bit of detail to them, right now theyāre pretty much just grey blocks.
Other than that itās perfect, but once you have those I think you could fool people into thinking it was real.
If you want the wheel to have actual tread (3D not just texture), there is an easy way to do it - make the tread like it would be flat, like:
| ā | ā | ā | ā | ā | ā | ā |
|---|
And then select it and apply a bend modifier, 360 degrees and ta-da it is now round instead of flat. I donāt know what the bend modifier is called in bryce, but Iām sure it has comparable. You can even make the tread with a linear array, making your job even easier.
Thatās definitely not an Alex DX32 rim. Itās too narrow, and the dx32 is black. That looks like a stock Torker Chrome rim.
But considering the fact that Iām arguing what style rim itās got, itās quite good! When I was quickly scrolling through the page, I thought it was a picture of a real unicycle. 
It looks like titanium to me, that would be thick enough.
Ok, hereās the updated model without the background. I added treads to the tires and pedals along with a seatpost clamp.
would you mind if either of these images were used in the magazine?
Sure, you can use it if you want, just so long as you say Iām the author
PM me if youād like it in a different size so I can re-render it
See the weird texture rings on the wheel? They look like theyre from mapping a box or planar texture UVW onto a circular surface.
You should apply a cylindrical UVW to it to get rid of the weirdness.
I would if bryce supported different mapping methods 
. Unfortunately it doesnāt.
Hereās on final version of the uni with a little bit of background. I also fixed the tire texture a little
Nice,
as a wheel builder i would like to see nipples pleaseā¦

Eh? What are those? Is it the thing you put air into the tire with 
Iām not very good at lingo 
They are the bits that join the spoke to the rim.
The red bit in this picture:

The bit you blow the tyre up with is the often refered to as the valve (although it is really the valve stem imho)

Well, I donāt know if I really want to put those in
There a rather small part that really wouldnāt make the uni look much different (plus when that img took over an hour and a half to render, I really donāt want to have to do that again)
If I try making a REALLY accurate uni sometime Iāll include those.
