Lots of us here love unicycles and perhaps our passion is less than objective, so I thought we could put our heads together and discuss some of the real boons of unicycles and unicycling.
I’ll start with the obvious:
Unicyles are generally smaller than bikes with fewer moving parts to break.
Hands free is a good one, although many bike riders can do this, too.
well, smaller size as you mentioned, but I also think that unis are a lot more manuverable than bikes in technical stuff (only one wheel, so you can thread rocks better). Unicycles are safer than bikes. I’ve never broken myself on a uni, but I always seem to die on a bike. I think unis area a little better at some uphill, but I’m not really sure about that. Unicycles are cheap, a top of the line KH is the best stock uni you can buy, but it’s only $500. A top of the line stock MTB will cost you over $1000 (you need more unis than bikes though).
you can ride backwards.
it gives me a free mind when im muning, i dont think about anything i just do it and it feels great, its almost like getting high i would suppose, cause i am just free and have no worries so it feels great when i muni,
so whats practical?
it sets me free from the real world i guess you could say
Unicycles are definitely a lot safer than bikes…also, the most important thing is that you can ride with no hands, so you can like eat or read a book or smoke or whatever you want while unicycling.
you can only go so fast
A great workout, works your legs and your core, increases stamina and your balance =p
unicycling weeds out the non hackers who do not pack the gear to serve in my beloved core!(ha, i love that movie) but seriously it kinda true. ive read write ups of men and women muni ing with mtn bikers and keeping a good pace to keep up with them. id like to see any seasoned mtn bike rider do that. it takes alot more focus and determination to ride a unicycle and certainly alot more stamina.
i remember seeing an espn clip about/ with kris holm where they tested his balance on a scale or a machine and gave the results. that would be good if you were doing this for a report.
they can ride with you on the public transportation and people don’t act a fool about you not wanting to set your $1000 mt bike on the bus rack on the front of the bus (i saw one get jacked last year in SAV…that thing was gone in seconds).
if you’re into rippin up the street scene, people (security guards, cops, teachers) don’t tend to mess with you as much if you’re not breaking stuff. (that may or may not be true with inline skaters, sk8tboards, bmx…).
if you’re not sober, it’s a great way to fake it while downtown. i don’t think anyone has ever been issued a public intoxication citation or a UWI (uni while intox) while atop a uni…i hope i don’t become the first.
if you see a person you don’t know riding a unicycle, you make a new friend right there on the spot, not the case in many other activities.
it’s like a super power.
Faster than walking, but you have to pedal downhill so you still get exercise.
And they’re not allowed on public transportation here :’( But I have a car 
Also, I can keep my trials uni in my car at work, and during my lunch I can try new stuff even in a flat empty parking lot.
Here’s a link to the clip I think you’re talking about.

It’s 15.2 Megs so it may take a minute. Apparently it really helps your balance!
There is nothing particularly special about most other modes of transportation. When you ride by people on a unicycle they generally smile. You get to wave at kids with their mouths open. You being there is a highlight of someone’s day.
Unicycles are fun to ride. They make you feel good and can make massive improvements in self-esteem.
yeah my friend (uniquely columbian) when he was learning and was at the stage where he could ride 2 metres no more he said and i quote “wow dan i can really see why you ride this this thing it just feels good”
Zero turning radius
I really like the feeling of manoeuvrability I get on my unicycles. Bikes are so big and clunky to ride.
The hands free thing is a huge plus, too. (Let’s see anyone riding with no hands on a bike still turn as well as I do on my unicycle.)
Unicycles are also lighter than bikes, which makes it easier to hop.
I like the portability and simplicity of it all. Fewer moving parts to break and much more robust than a bike. You can take it around the world and it comes out in one piece. You can throw it off a 5 story building and still be able to ride it. And it’s cheaper than biking as there are less parts to break, and in general, unicycle parts are cheaper than bike parts.
To the people that said it’s safer than a bike- what a load of C#@!.
In 15yrs of competitive Mountainbiking I’ve had a cut to my arm requiring 7 stitches. In 5 yrs of unicycling I’ve had 3 sprained ankles, 1 broken ankle, 1 broken Tibia/fibula, a broken triquetrum, an AC joint dislocation, 8 stiches to my leg, and multiple scars on my leg from pedal bites.
Do you think you would have ridden a Laos Tour on a MTB with, let’s say a known brake or stearing issue;) 
?
I guess it’s like JC said: good for self esteeme… in your case: a good way to push your limits further, wich might not be the case when you MTB?
idling, because… ummm… you guys know what i mean
