A cycle with only one wheel, ridden by balancing and pedaling, requiring significant skill and coordination.
From Latin 'uni-' (one) and 'cycle' (from Greek 'kuklos,' wheel). The word was coined in the 19th century as a novelty and entertainment device, though it became a competitive sport and circus act.
Unicycling seems impossible until you understand the physics—riders lean and use pedal pressure to maintain balance in a way that's actually quite elegant. Mountain unicycles can now tackle serious terrain, and competitive unicyclists perform tricks that rival skateboarding!
