Technique #1 How to Ride a Unicycle
1. Have two friends stand on either side of you. Get up on the unicycle and grab a hold of both your friends on either side, by putting your arms around their shoulders.
2. Sit up straight. Put your weight on the seat, not the pedals. Get the feel of the unicycle by rocking back and forth. Get the pedals level so you are in complete control over the unicycle.
3. Start to pedal forwards, as your friends move with you. Go slow and steady. Try to stay atop the unicycle for as long as possible.
4. Once you get the hang of this, switch to holding your friends' wrists.
5. This time, hold on to only one of your friends' wrists.
6. Now, go back to two friends. But, only use their support to help you get on. When you're ready, start going forward holding onto your friends, and then let go of both your friends.
7. Continue doing this, one attempt right after another, and you'll start to get farther every time.
Reminders: Steps 1-5 should be done in about 10-15 minutes...

Technique #2 – How to Ride a Unicycle
This technique for learning is to learn on your own.
1. Go to a sturdy object, such as a shed or the side of your house. Hold onto the object with both hands and mount the unicycle.
2. After mounting, rock back and forth to get a feel for the unicycle.
3. Align the pedals horizontally with your dominant foot forward.
4. Slowly pedal forwards. As you move along the object, continue to hold on with both hands.
5. Do this until you are comfortable.
6. Switch to holding onto the object with only one hand.
7. After you are comfortable with riding alongside the object while holding on, hold on at first and then let go. See how far you can ride without holding on.
8. Once you can do the whole length of the object, try riding away from the object, instead of alongside it.
9. Continue to ride like this, and you will gain distance almost every time you work at it.
Whatever you do, work to have FUN! The payoff will be worth it.
"Learning to ride a unicycle is 60% determination, 35% persistence (not giving up), and 5% sense of balance."-- John Foss
