Editing Unicycle (section)

==Unicycles compared to other pedal powered vehicles==
[[Bicycles]], [[tricycles]] and [[quadracycles]] share (with minor variations) several basic parts including wheels, pedals, cranks, forks, and the saddle with unicycles.
Without a rider, unicycles lack stability – however, a proficient unicyclist is usually more stable than a similarly proficient rider on a bicycle as the wheel is not constrained by the linear axis of a frame.
Unicycles usually, but not always, lack brakes, gears, and the ability to [[freewheel]]. Given these differences, the injuries that can occur from unicycle use tend to be different from that of bicycle use. In particular, head injuries are significantly less likely among unicycle use compared to bicycle use.<ref>{{Cite journal|last=Wang|first=Marvin L.|date=October 2013|title=Unicycle injuries in the United States|url=https://pubmed.ncbi.nlm.nih.gov/23871477/|journal=The Journal of Emergency Medicine|volume=45|issue=4|pages=502–507|doi=10.1016/j.jemermed.2013.05.024|issn=0736-4679|pmid=23871477}}</ref>
