  1. Beginner 5 Star Review

    Posted by on Dec 20th 2014

    I'm truly excited as I've just purchase this, my first unicycle yesterday, 19 Dec 2014 here in Korea. I've only spent a total of 15 minutes and I can balance on it. I've also turn the cranks 2 rotations today and I'm stocked! Wish me luck as I head to 15 hours of practicing riding my new toy!

  2. This is a great unicycle for a beginner! 5 Star Review

    Posted by on Apr 24th 2014

    I started riding on March 23rd. I am 57 years old and have always been pretty active. I like to ride bike and walk and just be outside. I was reading the Duluth Trading magazine and I saw a picture of a woman riding a unicycle out in the field and It just hit me that I wanted to do that! I talked to the people at and they suggested this model. I practice about a half hour at a time and I am right at 14 hours and I can go on my own for small distances. I feel like I am almost there and I can tell that it is going to be great! This is a comfortable model and I do like the seat. I put on the better metal pedals as well. I put it together by myself which is no big deal but the fact is that it is pretty easy. My only problem was putting too much air in the tire and it blew. That was my fault and I learned my lesson.

  3. Great all-purpose unicycle 5 Star Review

    Posted by on Oct 21st 2012

    This was my first 24", and it's great. It is very well built, and the wheel and bearings run smoothly. I was able to do some tricks on it, and even some muni. Although it seems a bit pricy for just an average unicycle, the quality is great and it is very comfortable. The only problem I had with it was that the crown kept catching my knee... but I learned to adapt. I highly recommend this uni for all level riders.

  4. Love It 5 Star Review

    Posted by on May 3rd 2011

    This is my first and only unicycle, but I love it! I beat it up quite a bit as I learned to ride, and it's held up very well.

  5. Add to cart! 5 Star Review

    Posted by on Mar 30th 2011

    My Dad always says ," The quality of the product is remembered long after the price is forgotten." Here you get a great uni for what I feel is a great price. Don't sell yourself short on a lesser model. Even if your're just beginning, " Add to cart." You won't be disappointed.

  6. Great unicycle! 5 Star Review

    Posted by on Mar 1st 2011

    I bought this unicycle about 2 weeks after learning to ride on a 20" trainer. It has really been great, and I love how sturdy it is. I have two comments that might be useful to others. First, if you are still a little shaky on free mounts (like me), definitely upgrade to some larger petals like those found on the Nimbus trials bikes. The pedals that come with this cycle are small and hard to hit with a good foot position when learning the free mount. Second, opt for the 145mm crank arms (stock is 125mm) if you have even moderately hilly terrain. I bought the 145mm arms on sale and mounted them, and I was really surprised at how much easier it was to ride up and down even moderate hills and across rough ground.

  7. great uni 5 Star Review

    Posted by on Jan 17th 2011

    I just got this one and I'm loving it. This is not a street tricks uni, but its great for cruising. I did changed the seat for the KH freeride, and add metal DX pedals, it works and feels great!!!

  8. Good First 5 Star Review

    Posted by on Jan 6th 2011

    This was my first uni and it's definately a quality unicycle. I have put it through alot of abuse on jumps and tricks. I highly reccomend this uni as a starter or even intermediate rider.

  10. Awesome 1st Unicycle 5 Star Review

    Posted by on Aug 22nd 2010

    This was my first unicycle, so I wanted it to be durable enough to last as I put it through more abuse and versatile enough to let me learn as many different things as I could. I will say that a 20" would have been easier to learn turning on, but I love the 24" for ability to go quicker for long rides and handle rougher terrain without me noticing. I've since replaced the kenda tire with a knobby MUni tire, and I replaced the saddle with a KH Freeride Fusion. I'm eventually going to add brakes and a KH T-bar handle set and finish the MUni package. My only problem was that the 1st saddle had a faulty bolt/hole, so I traded up for the fusion and paid the difference. They were cool and worked with me on that, but it sucks to have to pay the return shipping for a defective part. That's a problem with UDC customer service, not this unicycle.

    I would definitely recommend their Nimbus II 24" line to new riders that plan on doing anything more than just rolling around. If you want to hop or put it through any abuse, the Isis hub is the way to go. Pay up for the nicer saddle though!
