Built to withstand abuse, the KH20 is a top quality unicycle designed for trials, street, and flatland riding. It has been the preferred unicycle for multiple World Unicycle Trials Champions and multiple top 5 finishers in World flatland and street riding events.

The small wheel and fat tire are nimble and absorb shock, with small rim drill-outs to maximize strength while reducing weight. The KH frame is strong and lightweight with an abundant use of one-piece forged components ensures high strength and durability. It also excels as a durable mountain unicycle for kids.

Highlights include

  • One-piece forged, 7005 alloy frame crown and neck for high strength without bulk
  • Slim (93 mm) crown combines a flat section with fork blades that curve inwards at the top. This prevents bashed knees while enabling frame tricks not possible with a fully rounded crown
  • KH Boundary Hub and Cranks with Q-Axle micro spline for high strength and stiffness
  • One-piece forged seatpost for high strength
  • Fusion Slim saddle is easy to grab for tricks

Out of the box this unicycle comes equipped with carefully chosen component choices that balance the needs for the majority of riders.

General Minimum leg inseam length (ground to crotch, wearing shoes) for KH20: 64 cm | KH20 LN: 75 cm
Note: minimum leg length may be reduced by 25+ mm by selecting different components, such as a slimmer saddle model and non-adjustable seatpost (to reduce saddle height), and shorter cranks (to raise the lowest point of the crank rotation). Advanced users may also shorten the frame seatpost tube by up to 25 mm. Note that frame modifications void the KH warranty.
