  1. Woohooo! 5 Star Review

    Posted by on Sep 5th 2018

    Very happy with my latest purchase of the 36 oracle. If you enjoy riding you uni, which I'm sure every uni rider does! consider the 36. Started taking my 20" on local forest preserve trails, but wow was i slow! So last year I upgraded to the 26" muni. What a difference. What once was a huge journey to go a couple miles turned into an adventure where I could go just about anywhere with ease. I grew to really enjoy putting in some miles on my muni. Quit smoking cigarettes and thought that was a good excuse to fork out the money to buy the 36" Oracle. I couldnt be any happier with my decision. This uni cruises! Im a little faster than the average jogger, and at a fast pace. I can keep up with slow bikers. The brake is a huge help for going downhill, as once this wheel gets going it isnt as easy to slow it down like on a smaller wheel. Just added some safety bike lights, as this uni has become my favorite way to get around. If you have the extra money, dont hold back!

  2. The Big One 5 Star Review

    Posted by on Jun 30th 2017

    My 36" Oracle finally came! Ordered it on a Monday and it showed up on my doorstep that Friday with no issues. I must admit I was leary about the price tag, being a recent college graduate with not much money to name, but when the 36 is calling your name, it's better to just give in. I've been cruising on a Nimbus 29" since college and have been waiting ever since to find a good reason to up my one wheel game by a few inches. I cannot wait to take this thing out and see what kind of speed I can get out of it!

  3. GREAT PURCHASE FOR ME 5 Star Review

    Posted by on Jun 2nd 2017

    I'm 56 and I just quit playing tennis.
    Needed a new hobby/exercise.
    I have a small unicycle, and I decided to try the "big one" to ride around on the island where I live.
    This thing rocks.
    It's so much faster than the smaller unicycles.
    Kept up with a semi-speedy jogger today.
    Very solid and smooth ride.
    Trying different psi, so far I like 40.
    Love the color.
    Have tried it with the 125mm and 150mm cranks.
    Much more control with the 150's, but noticeably slower.
    Great workout, challenging, fun, supreme attention getter, and no butt heads to deal with like in tennis.
    I'm hooked.

  4. great, very satisfied 5 Star Review

    Posted by on Nov 30th 2015

    i'm very satisfied with my purchase, this is an awesome unicycle, i already have oracle 26" which helped me learn to unicycle, now this is my second step and is great! i'm not a master but i can freely move once i'm up, still need some post, car or wall to clim it, jiji. this unicycle is made of light weight materials so it handles very good and easy, i also installed the bar, bottle hanger and basic computer so i check my speed, whis it, top 11 miles/hr. not to bad but still slow, i wonder how to keep the pace..... well, i really recommend this unycicle to everyone. i wish Florian developes a geared hub fot it.

  5. Smooth, stable, fast, and comfortable 5 Star Review

    Posted by on Dec 31st 2013

    I learned how to ride a unicycle last year. It's really exciting! I quickly went from a 20" to a 24", and now this 36". It was an easy and enjoyable transition. I upgraded to a KH gel saddle. It has been the most comfortable and smooth ride yet. I also added a KH T-bar for added stability. I average 5-6 miles/ day without any complaints. My longest ride so far has been 17 miles. I hope to beat it soon. I love this 36"er!

  6. Great 5 Star Review

    Posted by on Oct 28th 2013

    I just purchased the 36in and road about 1 mile. My wife bought me a 26in in August so I have been riding for 2.5 months. I figured is was ready to move up. Well! This uni is very easy to ride an maneuvers almost as easy as my 26in. I'm quite surprised. I'm only 6 feet tall and I can truly say, the hardest thing about about riding this uni is getting up on the seat. Once up on's a quick beast. Nooooo complaints.

  7. A Quality 36 Uni 5 Star Review

    Posted by on Sep 18th 2013

    I have had my 36” Oracle for about six weeks and am favorably impressed with it in every way. The frame is lightweight, which helps compensate somewhat for the wheel weight and the build is flawless.

    Like the previous reviewer I installed the KH bar and have found that it adds immensely to the stability, smoothness and hill-climbing capability of this uni. I also added the KH starfighter, a wireless cyclo computer and replaced the stock pedals with Wellgos. The wheel and tire are first rate and they offer a good compromise between street and light off road riding. I would consider this uni something of a hybrid build vs. a dedicated MUNI or pure street vehicle. I actually like the wheel color as I think it adds extra visibility on roads shared with cars and trucks. I also did the KH saddle and (127/150) Spirit crank upgrades (for versatility)

    While the quality is high and I have no complaints, I cannot fairly compare or contrast it to other 36” unis sold by UDC or elsewhere. If you read the reviews on the web all have their own advocates and detractors. I will say that despite the expense, I find this a very good value given that it comes with an installed disc brake, has a lightweight aluminum frame and offers numerous upgrades at a fair price. I have several other Nimbus Unis and have found all to be reliable and without manufacturing defects.

    UDC always is quick to respond to email inquiries and their shipping is fast and free (over $300). How can you beat that? I wouldn’t hesitate to recommend this very fine machine to anyone considering jumping up to a big wheel

  8. Great Ride 5 Star Review

    Posted by on Jun 24th 2013

    Got mine with a custom wheel build, Oregon hub and black rim. I couldn't stand the green. I was told the Oregon hub would be more durable. Got the KH street saddle, KH tbar and 127/150 cranks.

    - Ride quality. Glad I got it. Makes the ride much more pleasant. I don't feel I lose much in terms of agility or hill climbing from the 29er, but gain a lot in stability, speed and fun over a longer ride. However, I am currently riding on the 150s while on the 29er I always ride on the 125s for road. At some point soon I'll try the 36er with the 127s. On the 29er I get bumped off once per 14 miles if I am not entirely focused. I can't see that happening as much with the 36. The ride quality of the Oracle is fantastic--it's simply the nicest unicycle I've ever had. The frame, even though it's AL really soaks up vibrations. The tire is great on-road and off. The higher stance on the 36 did force me to dismount a few times on my commute to avoid hitting my head, but I think I can find a slightly different route to avoid that. In most cases I was able to easily duck to avoid branches etc.

    - Bars: I love them. I moved the handles in an inch or so, and that helps with braking quite a bit. However, I think a brake extender would make braking more comfortable by offering a larger target. I will probably get one soon. I think the bar stabalizes the core and forces the rider to square the shoulders more. I had no problem getting used to using them and wouldn't want to ride this beast without them.

    I am very happy with the Oracle 36. It's an excellent product and as always the customer service at UDC is phenomenal. Now that I see how fun a 36er is I can see why people gear up. However, I won't be able to put a geared hub on it. If I ever get to the point where I think I want to spend that kind of money on one I'd probably sell the Oracle and get the KH. Or reuse most of the parts. UDC/Nimbus is a great company we should all support, and I thank them for guiding me through the process of transitioning to a 36. I'm glad I did.

    If you are an intermediate level unicyclist and are comfortable on the 29er, you will have no problem getting used to a quality, light 36er like the KH or Oracle.

  9. Test-Riding the Prototype Oracle 36 5 Star Review

    Posted by on Nov 23rd 2012

    I had the opportunity to test-ride the prototype Nimbus 36” Oracle at the 2012 Outerbike gathering in Moab, Utah in early October. The “proto-36-O” was equipped with Nimbus 150mm Venture 2 cranks with and Venture pedals (stock), a Nimbus Shadow Handle (add-on), Nightrider tire with Nimbus/Foss tube on a Dominator 2 rim (stock) and Tektro Auriga SUB brake (stock). I rode several miles on a paved rail-trail and a rough and bumpy dirt road connector.

    I found the Oracle to be light, super-responsive, and very nimble. The rigidity of the Oracle frame (as compared to my Nightrider 36er) was apparent in two distinct way: zero flex when pushing hard up hills, resulting in more efficient energy transfer from the pedals to the wheel, and no vibration/hum of the frame when moving at speed on smooth pavement – just a gentle whirring of the tire and whoosh of the wind. And the brake (as compared to the Maguras on my N36) was oh-so-buttery-smooth!

    By the end of the ride I was seriously considering trying to talk Josh & Amy into selling me the "proto-36-O," but they had plans for it (and the prototype 29” Oracle) on their return to Georgia – so I took home a demo 26” Oracle instead (which has been a fantastic addition to my “stable”).

    The next generation of high-performance quality unicycles is here, and is now available in every major wheelsize: Consult the Oracle!
