Nimbus Hatchet 27.5" 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 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.
