My words of advice: ignore the unicycle and protect yourself.
Explaination: if your are just learning to unicycle, don’t worry about protecting the equipment from damage. Other than throwing it off your roof, a beginner will hardly be able to feel safe going over even a tiny bump, and a unicycle falling down because you stepped off isn’t going to get damaged. Skinned up it will get.
When you practice, think about landing on your feet, not grabbing for the saddle to keep the uni from crashing to the ground. Eventually you will know you are about to fall and then grabbing the seat will be possible.
How to practice. Some of us say ‘go for it’. I think this advice eventually works, so it is hard to disprove. But it isn’t efficient to just get on and try to pedal away from support. There is a natural progression in a lot of riding skills.
First you need to hold on to something with both hands in order to position yourself on the unicycle correctly. In the context of learning to ride, this means either a narrow hallway, or using two friends to hold you up, or maybe one friend and a wall. At any rate, you might need all the help you can get to get on the unicycle the first few times. Once you are on, the cranks/pedals need to be parallel to the ground, at 3 and 9 o’clock. Try sitting down on the seat with as much of your weight as possible, that is with as little force on the pedals as you can get.
Going along the wall, or down the hallway, pedal half a revolution, so that the pedals switch positions, to the next parallel position. This is the most stable position of the pedals, always try to stop with the pedals in this position. Keep doing these half revolutions until you get the hang of it.
Second: you will only require one hand to hold on to something. This is ideal if you have a wall, since it no longer requires you find a friend to help. Do the same exercise, graduating to full revolutions and so on. If you have a friend, doing this away from the wall would probably offer a better learning method.
Third: what you learn along the wall is how to fall off. Like I said above: at first you will have no clue when this will happen, and ‘bam’ you are on the ground. If you are learning along a wall or with a friend, the additional support will provide more time to react to the fall. Eventually you will know when you are losing control, and you will always land on your feet, or just step off.
Fourth: at the point that you can go easily 2-3 revolutions along the wall, do the same thing, and when you feel balanced, veer out into the open area away from the wall.
Fifth: find a track, and build up to a mile or more. For the first 1/4 mile, always start at the same place and measure your distance back to your starting point. A mile is required to ensure you learn how to relax and put more weight on the seat.
This method will not slow down your learning process, it will speed it up. The reason is you don’t learn anything much from going one revolution away from the wall, there just isn’t enough practice time. You fall off and then go back to the wall, remount and launch. The angle of launch, the position of the pedals, which pedal goes out first, are all variables you should not be exploring at this point, but the off the wall method requires you deal with them immediately. On the flip size, once you can do the 2-3 revs, (and can land on your feet every time) you are probably wasting your time doing too much more wall work, start veering off once you get started.
First learn to fall, then to ride, and wear pads! More importantly, don’t let any rules get in your way of enjoying the leaning process.
