It is also important to note the self balance unicycle was made to work comfortably and ride well. However, you should never ride the device with more than one passenger. The self balance unicycle is designed to only accommodate one rider at a time. Beyond that it will be strained and the damage that could result will be irreparable and can also cause serious body harm. At any given time avoid riding the electric unicycle if the device does not have at least 50 percent battery power.
