Regarding the use of ski poles and what have you as balance aids, the only real downside I can see to that is the heightened potential for injury. Falling off a unicycle is no big thing, most of the time you end up standing, but throw poles into the mix and there’s a chance of landing on the pole, which would be majorly uncool. That’s really the only difference from using walls, I’d say.

Unicycling is a fun skill to have, and it’s great exercise. When I had a unicycle, I rode it to and from class every day, which involved covering a fairly substantial hill, up and down. Once you’re comfortable with riding, it’s faster than walking (though this really depends on wheel size and what you consider a “normal” pedalling speed.), though not as fast as running.

If you get decently good at riding, it’s worth it to give juggling a try, because once you can do both, there’s some money to be made from people passing on the street, if that’s your bag.

Words of Wisdom for new riders: Lean your weight forwards when riding forwards, rather than keeping it straight above the wheel. This prevents you from falling off backwards, which has greater potential for injury than falling off forwards.

Definitely learn to idle. (Rock your pedals back and forth while staying in the same area.)

Practice all your skills with both feet evenly from the start, otherwise it will only be more difficult to learn later.

Basic familiarity with a unicycle can be gained in a weekend, just keep at it, don’t give up.

Enjoy!
