What Size Unicycle Should I Purchase?

Adults and Children (over 12 years)

Most adults choose a 20" unicycle to learn on, although a 24" may be better in some instances:

  • 20" is preferred by people who like to do tricks, eg. BMX riders, Skate boarders and Jugglers. It is better ridden on smooth flat ground.
  • 24" is preferred by riders who like to move. eg. Mountain bikers and road cyclists. This can be used on rougher ground than the 20" and needs more space to learn in.

Children (under 12 years)

Select the largest unicycle they can ride up to 20".

*WHAT DOES "CUT-DOWN" MEAN?

A unicycle seat is directly above the tyre, so when it is pushed down the seatpost will hit the tyre. It is absolutely standard procedure to cut the bottom of the seatpost off to allow the seat height to be lower if required (this will not effect your unicycle's warranty).

This is how to measure the Inseam:

You need to take a book (DVD case) and put it between the persons legs as if they were sitting on a Unicycle ( the same as sitting on a Bicycle seat).Now squeeze the Book between your legs, holding it as tight and as parallel to the ground as possible. Now with a measuring stick / measuring tape, measure from the ground to the upper edge of the book (please measure with shoes):

Here is a breakdown of the sizes and how they can be ridden: 

12" Unicycle This is a unicycle designed for a smaller child. It's good for children who are too small to ride a 16" unicycle, but it needs smooth ground and is not really good for outdoors. For children up to 5 year olds. 

Cut Down Seatpost: 18.5" (47cm) Minimum Leg Length: 19.5" (50cm) Maximum Leg Length: 24" (61.5cm) 

16" Unicycle This is a children's unicycle, the small wheel makes it only suitable for very smooth areas. Best used indoors or on smooth ground; not so good outdoors especially if it is rough or uneven, good for learning for 5 to 8 year olds (always check the leg length of your child to be sure) 

Cut Down Seatpost: 20"(51cm) Minimum Leg Length: 23.5" (60cm) Maximum Leg Length: 29"(74cm) 

20" Unicycle Traditionally the most popular size of unicycle. These are great indoor, they turn quick and the best size for tricks.. They are great for unicycle hockey or basketball.  The down side is that they make poor distance machines. Good for learning. 

Cut Down Seatpost: 24" (61cm) Minimum Leg Length: 28" (71cm) Maximum Leg Length: 33" (84cm) 

24" Unicycle This is a common size among adults for learning. The bigger wheel can be used for freestyle riding but can make some of the advanced freestyle tricks harder.  For mountain riding, this wheelsize is better for hopping and jumping and technical single track. 

Cut Down Seatpost: 27" (69cm) Minimum Leg Length: 31" (79cm) Maximum Leg Length: 36.6"(93cm) 

26" Unicycle This is a versatile size.  Great for taller adults to learn on and can be ridden on pavement to off road trails.  For mountain riding, this wheelsize is better for less hopping and jumping and more rolling over technical single track. 

Cut Down Seatpost: 29" (74cm) Minimum Leg Length: 32" (81cm) Maximum Leg Length: 36" (92cm) 

27.5" Unicycle  This is the newest wheelsize available and is great for all types of mountain riding.  Where this size shines is all the tires that are available in lighter weights and thickness. This is as aggressive as a 24, more agile than a 26.  

Cut Down Seatpost: 29" (74cm) Minimum Leg Length: 33" (84cm) Maximum Leg Length: 38" (97cm) 

29" Unicycle This is good for commuting and paved paths. For mountain riding this is ideal for fire roads and light single track.  

Cut Down Seatpost: 30" (76cm) Minimum Leg Length: 34" (86cm) Maximum Leg Length: 39" (100cm) 

32" Unicycle  This is good for commuting and paved paths. This wheelsize is faster but agile like the 29" unicycle. For mountain riding this is ideal for fire roads and light single track per the rider's skill level.  

Cut Down Seatpost: 30" (76cm) Minimum Leg Length: 33.5" (86cm) Maximum Leg Length: 38" (97cm) 

36" Unicycle This is the fastest wheelsize for commuting and paved paths. It can be harder to control because of the weight and diameter of the wheel but the speed you can obtain does offset the handling.  For mountain riding this is ideal for fire roads and light single track per the rider's skill level.  

Cut Down Seatpost: 30" (81cm) Minimum Leg Length: 29.5" (75cm) Maximum Leg Length: 40.5" (103cm) 

Note
These are approximate sizes only, check the website for the model you want. The cut down seatpost measurement is there to show the leg length after you have cut the seatpost shorter. If your legs are longer than the maximum leg length for that size unicycle you can always purchase a longer seat post.
