Hey, im new to the site and new to unicycling. Just looking for advice on what to get for a first time recreational practice uni. Im 6’4" and 150 lbs if either of those matter much. Dunno if i need a big frame or a big wheel. Any advice is much appreciated.
most people start with a cheep 20 or 24, at your height I would go with a 24.
If you like riding and would like to get into any of the disciplines (offroad, trials, distance, freestyle, etc) then you can spend a bit of money on something that will work especially well for your style, but to start almost anything works.
