Nimbus Hatchet 27.5" Mountain Unicycle

Usually ships in 24 hours

Product Description

The Nimbus Hatchet builds on the amazing platform that the Oregon created, and moves it onto the next level. The frame comes with the brake installed on a new precision IS mount. The hose is also clipped in place with special red aluminium clips. The main challenge with “Fat-Uni’s” is the requirement for a super wide frame. This can make it uncomfortable to ride as it catches the riders' legs. To resolve this the Nimbus Hatchet moves the frame behind the riders legs giving maximum clearance. 

  • This frame will hold a tire up to 26" x 5.05", 27.5" x 4", 29" x 3.0" and a 32" x 2.125.

    Note: Michigan Trail Tested, Mother approved!

  1. The Beast 5 Star Review

    Posted by on Feb 5th 2018

    This muni is awesome! After deliberating for several months, I finally decided to pull the trigger on this beauty. It looks awesome and has performance to match. Love it's unique lines and well selected components. The only CON I can think of is that the frame can contact the ground during a UPD. Usually the pedals and seat prevent this from occurring, but not with this wide body frame. Oh well, I can deal with a few battle scars.
