Nimbus 19" Gremlin Trials Unicycle - Blue


Product Description

The Nimbus trials unicycle was designed to ride over obstacles without any part of the rider touching the ground. The obstacles traversed can be set up specifically for the purpose of unicycle trials. These are often walls, railings, ledges and other "street furniture" found in an urban environment (also known as a session style sport).

Although unicycle trials can be performed on a standard unicycle, many are not equipped for the forces. Trials unicycles are designed and built with trials stresses in mind.

  1. this unicycle is very light and tough as a tank except fore the cranks. 5 Star Review

    I love this unicycle. I do a lot of hard riding. I am 6ft tall and weigh 165lbs and it holds up very well. The seat/frame/hub/rim and tire are perfect for trials riding. The only thing is the nimbus venture cranks after just three weeks of trials riding the cranks bent. I checked to see if it was the pedals that were bent but it was the cranks. but with the 137 KH cranks it is perfect! I definitely recommend this unicycle and for the price you can't beat it.

  3. Excellent First Uni! 5 Star Review

    Posted by on May 8th 2011

    My wife bought me this uni as my first. I started learning on a really cheap uni and this thing is a HUGE step up! I have NO complaints about this uni as it is very strong and is of outstanding quality. It may be a little heavier than I was expecting however I am more confident it'll last a life time. The green is more of a blacklight responsive green as it seems to glow at dusk...which is a pretty rad effect! I'll more than likely purchase another uni in the future, but this one is a KEEPER!
