Nimbus Hatchet 29" Plus 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 also means you can run some of the largest tires on the market, which includes the Snowshoe 5.05" tire.

  • 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. LOVING IT 5 Star Review

    Posted by on Apr 10th 2017

    shipped out to me, and I had it assembled and out in the driveway in a short time. Besides the firm seat I love the control I have and the ease of decent with this. Brake control is great. Best unicycle I have added to my collection since my first one, 22 years ago.

  2. awesome. 5 Star Review

    The 29" hatchet is so fun. It just barely fits in my (Crosstrek) trunk so I'm glad I didn't get a 36". It shipped to me missing the brake lever mounting bracket but customer service sent it out quickly. You will get so much attention riding this beast.
