We would compare riding an electric unicycle with the challenge of riding a bicycle. It is not at all difficult once you know it, but it would be foolish to expect that you can just step on an electric unicycle and you will be perfect.
There is some learning required and it does take most people a little bit of time, but it is definitely worth it!
We talked to one of the best pedal unicyclists recently who uses a 3m high unicycles in his shows. And he told us that it took him about 10 minutes to learn how to use an Electric Unicycle. And our own experience is that for average people that are a lot less “acrobatic”, it can take up to 5 learning days. If you are determined and have normal balance, you should be able to ride an Electric Unicycle very very soon.
