It will take a lot of practice to get used to moving backward instead of forward when mounting a unicycle. Take your time and be patient.
You want the wheel to rotate 1/4-turn backwards as soon as you mount the unicycle. Once you mount the unicycle, the pedals should be directly vertical.
Once you feel ready, you can learn to free mount by following the same steps above without the assistance of a fence or handrail. Instead, use your hands to hold on to the seat as you mount or use your arms to help you balance.
Make sure to move the unicycle and your body in one solid piece. Don’t just bend your upper body forward at the waist as doing so will throw you off balance and fail to propel the unicycle forward.
To accelerate, tilt forward slightly and apply more force on the pedals. To slow down, sit up straight and control the force exerted on the pedals. Be sure to keep your weight over the seat and refrain from tilting backwards when slowing down as this can be dangerous.
When you no longer need to hold on to something as you come down, you will transfer your hands to the seat simultaneously as you step down. This allows you to catch the unicycle instead of letting it to fall to the ground.
