  1. Sun experience 5 Star Review

    Posted by on Jul 10th 2014

    i had this unicycle for about 3 days before seat handles broke off and i had to epoxy them back on. Then 4 months later the axel broke off the hub. On the plus side the seat is very comfortable the frame seams to built pretty good and the k rad tire is nice. Needless to say i cant find a new wheelset for a reasonable price and i didnt want to buy a new hub then pay for a wheel build so i just purchased an impact unicyle, which should last more than 4 months i would hope. But overall i would say it is a good unicycle just dont plan on doing any jumping.

  2. Cheap piece of garbage 3 Star Review

    I bought this unicycle roughly one month ago and I've had nothing but problems with it. The clamp broke the day i bought along with the right crank, just yesterday the bearing casing fell apart and now i can't even ride it. If you look at the parts you can tell that they're very cheaply made almost look like it was made from aluminum, I would not recommend this unicycle to anyone.

  3. Not bad for begginer 4 Star Review

    I got a unicycle like this a couple of years ago, and it's awesome! It's pretty durable, and it's pretty easy to ride. It also has an good handle on the front, and the seat was pretty comfortable.

    The only problem that I've had with mine is the hub on it is not very strong, so it can't be used for trials without twisting your hub, like I did to mine. But if you're just interested in riding one, and doing minor tricks, it's a pretty good unicycle!
