Out of all my unicycles the Oregon is by far my favorite. The fatty tire is perfect for the terrain I usually run though since most of the trails I ride are muddy and soft. While some people might find the weight to be an issue, I find it reassuring. This is a very solid unicycle and can handle more bumps than I feel safe doing. Best to add a Kris Holm Starfighter Brake Lever Extension for easier breaking. (Posted on 2/15/13)

the huge tire definitely provides a cool, fast, floating ride, but is offset by the weight and bulk of the tire/rim which makes it somewhat of a beast to maneuver at times. I've since put on a 2.5 knobby and it's better for most situations. The build is good and I like the disk brake. I usually ride my 29"KH though, it's faster and more fun and with the larger diameter tire rolls smoothly over most obstacles. This is a good specialized machine for sand or surfaces where a super-wide tire would be useful. (Posted on 10/8/12)

This is not a unicycle for new riders, it takes some saddle time to adjust to riding a big wheel, but in certain situations the fat tire rules; snow, mud, and absorbing impacts. I don't tend to ride it as much in the dry season, I prefer a taller wheel so I can ride faster, so my son has been riding it as his only unicycle. For the Summer we installed an Intense DH 2.5" which works great and make the Oregon feel more like a typical 3" tire; the 65mm Large Rim really spreds out a tire.

I have two fat tires I run in the winter, a Devist8er and the Larry, not that there's anything wrong with Larry, but it's a little soft and bouncy at times. The Devist8er is a heavier tire, armored with Kevlar, and it tends to autostear a whole let less. I have also run a Big Fat Larry 4.5", which is just a fatter Larry, and it was fun, but not any better for riding and it had terrible autostear.

The Oregon's steel frame is light and strong, no noticeable twisting. I have mine set up with a KH Freeride seat, Thompson post, QR clamp, and QuAx Chromoly Street Cranks 170 mm's. The QuAx cranks have about the same Q facter as the KH cranks, so it is a wide foot stance compared to something like the Oracle, but I tend to prefer a wider stance for increased stability and reduce saddle rub.

This Oregon is very unique in that it willl accomodate the biggest tires available, including the Big Fat Larry and the soon to be release Surly Knard, a 29 x 3" ; the Oregon frame is the only production frame that will fit this new tire!! I terms of quality and design, the Oregon is a great uni for someone who wants the biggest and fattest uni around.

The Oregon was my first uni with a disc brake. I now have four unis with disc brakes, a 36er (Impulse with an Oregon hub), KH 29 (Oracle hub), KH 24 (Oracle hub), custom 32" (Oregon hub). Hub mounted rortors are definitely the way to go, easy to maintain, you can run any crank you want, and the frame protects the rotor from impacts.

A really nice thing about disc brakes is the ability to swap wheels without having to mess with the brakes. I have two wheels for my 36er (32", 36") and shortly I will be adding a 29" wheel with a Knard to the Oregon. Two unis and four wheels, four bolts, quick change and I'm back on the road!!

*Now to qualify that statement:
Universally, the first detail noticed about the Oregon is the mammoth tire- a Surly Larry 3.8in wide mounted on a Large Marge rim. In fact, the Oregon is only 1 of 3 production unicycle frames that will clear the beastly combo. The other 2 are the Surly 26” Conundrum (no longer in production) and the Triton MUni frame. I’ve now experienced all 3 frames.
Getting almost a 4in wide tire to clear a unicycle frame isn’t an easy task. The small diameter tubes of the Oregon keep the overall crown width to a minimum. The dual crown design keeps the frame from flexing too much; more on that in a minute.
The other attention getter of the Oregon is the inboard disc brake. Nimbus is the first brand to embrace the inboard disc design, having both the frames and hubs manufactured to their specs. Fitting a disc inboard while keeping a reasonably strong wheel build required moving from the 100mm standard bearing width to a 125mm width- the common width for 36” wheeled unicycles. Even with the wide hub, there still isn’t a lot of clearance between the brake caliper and the spokes. Only certain brands of brakes will work with the setup. Fortunately Unicycle.com has done the homework.
Enough about the hardware specs. Unlike bicycles, it’s hard to find a lot of places to test ride unicycles. This makes the ride report extremely valuable.
The first thing you’ll probably notice is that the Oregon is a bit hefty, but not as heavy as it looks. Surprisingly the weight isn’t too bad as the Larry is lighter than the 3.0 Duro tire. Once on the trail, the Oregon’s weight isn’t that noticeable.
The tire volume is, however.
Having spent close to a year on the Larry (on my Conundrum with 150mm cranks) I’ve come to the conclusion that it does at times have a mind of its own. Off camber situations coupled with low pressure (less than 20 psi) can cause it to pull. I’ve discovered trusting Larry by hanging on and pedaling gets me through situations I never figured I’d survive. Proper tire pressure is critical. Too much loses traction, and too little can cause it to act like a pogo stick on Ritalin. Taking a bit of time to find the sweet spot is well worth it. I’ve found when I hit the right zone for the trail the 3.8 is every bit as fast as my 29er- if not faster. In addition to the speed the shock absorption is incredible. The volume allows the unicycle to plow through situations that would hang up lesser tires. When hopping, the spring available from the tire is tremendous. The 65mm wide Large Marge rim gives great support to the tire during side hops or Pecking. From my personal experience a tire as small as a “large” 2.5 can be used successfully with the LM rim.
I had some initial concerns about the Oregon: crank length, crown width, Q , and torsional stiffness. The 165mm long cranks on the Oregon are 15mm longer than what I’ve been running on my Conundrum. I’m a fan of short cranks (as low as 100s on my 36er for road riding), but the 165s really make sense on this uni. With such long cranks I thought the Oregon would ride comparatively slow, but those fears were unfounded. The almost 29in diameter of the tire helps keep the speed up.
I had to send my Triton to a new home because the crown was too wide. The Surly works for me, but once the Magura rim brake calipers are installed it’s really close to my legs. The frame of the Oregon offers the most clearance out of the three.
Q is the distance between the pedals. I typically like the smallest distance possible. The Oregon is about 1in wider than any of my personal unis. I figured the extra distance would put a strain on my knees. Surprisingly, it didn’t.
I really like climbing. I’m able to pull on the seat enough when climbing to make the brakes rub on most unis- my stiff KH 36 included. I noticed a lack of flex in the Oregon. I realize it doesn’t have discs, but there isn’t a lot of lateral clearance between the tire and the frame. The KH stiffener plate installed on the prototype, in theory, should put the maximum force through the frame. Even with all that force through the frame I never noticed the frame twisting.
I spent 15-20 hours aboard the Oregon over the month of August. I climbed some pretty steep technical off road trails. I descended trails too steep (and loose) to climb. I took it down 2ft+ drops and through rocky rooted technical sections. I rode it for 3+ hour rides. I didn’t take it easy or treat it gently. I rode it as hard as I could. The only conditions I didn’t get to test the Oregon in were rain, snow, and excessive mud (responsibly). From personal experience I can say that the Large Marge with an aggressive tire works better than lesser unicycles in adverse conditions. The vertical tire clearance on the Oregon is fantastic- better than any other unicycle. This should really help in the mud and snow.
Do I like the Oregon? Absolutely.
Would I recommend it? Yes, but not to a brand new MUni rider as it sits. The tire rim combination is a bit excessive for some situations. Fortunately I’ve found that a 3.0 Duro (or even a smaller tire) changes the feel of the unicycle completely. I’ve had a 2.5 Specialized Butcher on the Large Marge (on my Conundrum), but I wouldn’t want anything smaller for it. Dropping the tire size makes shorter cranks a consideration. Andy, one of our other local testers, noted that he experienced a learning curve moving from his 26” Nimbus (with a 3.0 and 150 cranks) to the Oregon. An inexperienced rider’s needs would be better met by another uni in the Nimbus line.
That being said, for someone who is looking for a second (or third, or fourth, or fifth) MUni, the Oregon is definitely worth considering. I still keep other MUnis around as the huge rim/tire combo is sometimes a bit excessive.
But sometimes excessive is just right.

I bought one cause it was a nice adition to my collection. I thought it would be a good snow muni. dont get me wrong it is but its just so dam heavy I mean this thing weighs more than my 36er. I dont recomend it for technical muni or drops and jumps its to heavy for that but it is a fun snow muni I ride it down ski resorts in the winter and I have put in miles on my local Vast snowmobile trails. all in all I would recommend a KH muni over this anyday but the frame is an eyecatcher.
