Typically, new riders start on 20-inch unicycle height. This site has proven to be the best fit and most appropriate. Children who can’t fit in a 20-inch will require an 18, 16, or even a 12-inch. Select the largest unicycle that still fits while keeping it compact enough for them to comfortably reach the pedals.
The average adult starts on a 20-inch unicycle. Longer Saddle posts are available if the saddle cannot be raised high enough. Adults can start with a 24-inch, though, if they already know that’s what they want. Due to the extreme difficulty, beginners hardly ever use the larger unicycles.
There is no general guideline for what lumbuy unicycle height corresponds to what height. The child’s inseam and the unicycle’s minimum inseam are what determine this. Despite the same wheel sizes, each unicycle has a different minimum inseam.
The rider should measure their inseam when selecting a unicycle size. The inside leg length, or inseam, is determined by measuring the leg with shoes on from the crotch to the floor. For an accurate length measurement, people who wear loose pants might want to measure the inseams of their underwear or shorts. Cycling shoes should also be worn so that the inseam length accurately reflects the appropriate footwear. A unicycle can be chosen after the inseam length has been established.
Circus performers and others are most fond of the 20-inch (50-centimeter) unicycle. This size can perform tricks and is reliable as well as simple to work with. They are appropriate for people with inseams between 24 inches (61 centimeters) and 33 inches, and they can be worn both inside and outside (84 centimeters). Cyclers with longer legs will need to lengthen the post; those on the shorter end of this spectrum will need to shorten it.
Children who are just learning to ride or those with very short legs should choose a unicycle that is between 12 inches (30 centimeters) and 16 inches (40 centimeters) in size. These unicycles will feel awkward and unbalanced to the majority of adults. For cyclists with longer legs, larger sizes are available. Unicyclists can typically move more quickly and perform more tricks when they are larger. Moderately short-legged riders can use the posts because they can be shortened to a certain extent.
Most vendors offer size guides and are happy to help cyclists choose the right unicycle. Larger sizes are preferable for speed and complex movements. While children should be given smaller ones, the 20-inch (50-centimeter) is the best option for versatility.
THE RIGHT SIZE UNICORN IS REQUIRED. You will struggle greatly if it is not the exact right size.
Your legs will quickly tire if they are too low or too small. If it is too tall, it will be impossible to ride.
Street, Trials, Freestyle, and Flatland:
If you had two unicycles, you would configure them differently for street/trials riding and flatland/freestyle riding.
For street/trials, you would have a lower seat height, a 19-inch rim, a 3-inch tire, and typically 137mm or occasionally 125mm cranks.
Your seat would be higher, your rim would be 20 inches, your tire would be 2 inches wide, and your cranks would be very short for flatland/freestyle (100mm on average).
Changing the seat’s height:
General recommendation: When starting on a 20-inch unicycle, make sure the unicycle reaches anywhere between your belly button and 1 inch above it. This is acceptable when starting muni for better clearance, a seat set at a lower height may be helpful when learning free mounting or hopping. Try lowering the seat so that you can sit on it and almost stand up with your feet almost flat on the ground.
The highest seat height is useful for wheel walking, riding, idling with one foot, or both.
For the strongest pulling position for hops near their highest point, set the seat height as follows:
With one hand on the seat handle and the other on the railing’s free hand,
In a still standing position, stand up (on uni with pedals flat – equal height from ground).
Legs should be straight while holding the handle:
When your legs and body are fully extended while standing, your seat should be high enough so that the seat is pulling slightly. Standing up, cranks horizontal, and just being able to reach the handle without stooping is the best pulling position. Both seat-in and seat-in-front hops can benefit from this.
The proper tire pressure:
You might want to start with a little bit lower tire pressure (15-22 pounds pressure).
For hopping or riding over rough terrain, 15 pounds of pressure seems to be the ideal amount.
Later, increase tire pressure when traveling far distances or when attempting to travel quickly (40 plus pounds).
Reduce tire pressure and lower the seat so you can stand with both feet on the ground while sitting on it when learning to free mount or hop.
