What to look for when buying a unicycle. This chapter assumes that you want to buy a unicycle for beginners. Unicycles for advanced riders should meet specific requirements depending on what you want to do with it (e.g. MUni, trials, touring). In that case, not all of the text below applies. Size: the size of a unicycle is characterised by its wheel diameter. The most common sizes are 20 and 24. For ages 6 and up, a wheel of 20 suits well (also for adults). From age 12 upwards, you can also get on well with a 24.
Get the right size. âThe main thing with kidsâ bikes is having the right size bike for the rider,â says Jon Posner, store manager at Race Pace Bicycles in Ellicott City. Childrenâs bikes are measured by the diameter of the wheel, with sizes ranging from 12 inches to 24 inches. The appropriate size depends on the childâs age and height or leg length. For example, most 2-year-olds start on a 12-inch bike. To test proper fit, the American Academy of Pediatrics (AAP) recommends children sit on the seat with their hands on the handlebars.
