What does Cut mean? All 20", 24", 26", and 29" unicycles come stock with a 300mm long seatpost which can be cut down to achieve the lower minimum seat-to-pedal and minimum seat-to-ground measurements listed in the chart above.

How to measure your inseam
Here's a step-by-step guide:
Materials needed:
- A book or ruler
- A flat wall
- A measuring tape
Steps:
Stand against a wall: Wear the type of pants or shorts you'd typically cycle in. Stand barefoot against a wall with your back straight and your feet about shoulder-width apart.
Position the book or ruler: Take the book or ruler and place it between your legs, pressing it firmly against your groin. Make sure it's parallel to the floor, simulating the pressure of a bike saddle.
Measure from the top of the book/ruler to the floor: Have someone assist you or use a measuring tape to measure the distance from the top edge of the book/ruler to the floor. This measurement is your inseam.
Calculate saddle height
The saddle height for a unicycle is typically about 103% to 107% of your inseam length. Multiply your inseam measurement, in centimeters, by 1.03, 1.05, or 107% to get a starting point for your saddle height.
- Low saddle height - Good for learning: Inseam x 1.03
- Example: 30" inseam ((30 x 2.54)*1.03)/2.54 = 30.9" saddle height
- Medium saddle height - Good for technical riding: Inseam x 1.05
- Example: 30" inseam ((30 x 2.54)*1.05)/2.54 = 31.5" saddle height
- High saddle height - Good for distance riding: Inseam x 1.07
- Example: 30" inseam ((30 x 2.54)*1.07)/2.54 = 32.1" saddle height
Adjust and test: Set your saddle to the calculated height and test the fit. Ensure your legs can comfortably reach the pedals with a slight bend at the knees at the bottom of the pedal stroke. Your hips should not rock excessively side to side while pedaling.
Fine-tune: Make minor adjustments to the saddle height as needed. If your legs feel too extended or cramped while pedaling, raise or lower the saddle in small increments until you find the most comfortable position.
