Precautions and Preparation

4.1 Precautions

  • Please find a smooth surface to practice on.
  • Warm-up your body and ensure you’re wearing safety gear such as helmets, knee pads, elbow pads, and wrist guards.
  • Ensure the wheel’s battery level.
  • Check the unicycle for imperfections such as any looseness, or abnormal sounds. We also highly suggest pushing the unicycle by to see if there’s any friction between the tire and the case of the wheel.
  • • Have a friend assist you if required.
  • Please do not accelerate or decelerate rapidly, please also try to avoid overleaning or leaning too fast to prevent rider injury.
  • Padding up the wheel during the learning process is highly recommended to ensure minimal scrapes on the exterior of the wheel.

4.2 How to use
4.2.1 Starting on the unicycle
Hold the wheel with one hand and ensure the wheel sits vertically on the ground. Unfold the pedals and switch on the wheel, it will self-balance forwards and backward, if it does not, please ensure the wheel is upright. Quickly pressing the power button once the wheel is on will toggle different light modes. 4.2.2 Standing on the unicycle With the pedals unfolded on both sides please stand on it with your preferred foot in the center of the pedal. Balance the wheel under you by keeping the other foot on the other side of the wheel. If you are left-footed, keep your other foot at around 5 o’clock, and if you are right-footed please keep the other foot at around 7 o’clock. If you are having a difficult time balancing the wheel under you make sure you find a center point of balance between these three points: a) the bottom of the tire b)where the top of your leg touches the wheel c) your foot. Finding the balance point between these three points will allow you to more easily control the wheel under you.
4.2.3 Learning to ride forwards and braking
Whilst having the wheel balanced under you, use your non-preferred foot to push off and lean forwards to begin going forwards, once the wheel gets going please put your non-preferred foot back onto the wheel. Focus on balancing and not falling left or right. Try to look ahead rather than down! Have your hands out to help you balance! To come to stop simply lean back and the wheel will slow down and come to a stop. You may dismount your non-preferred foot when standing.
Note: The harder you lean forwards or backward will dictate the speed at which the wheel accelerates and decelerates.
4.2.4 Turning
When turning, lean your body gently to the side in which you want to go and straighten up when you want to go straight again! As you become more experienced at riding you will find other ways to turn such as; letting the wheel fall just side to side, just turning the lower part of your body, and leaning your entire body. Advanced riders will usually incorporate a combination of these.
