Street unicycling is one of the latest developments in unicycling. The aim of the sport is to use natural/urban/specially made obstacles such as ledges, handrails and stairs in a given area to perform tricks that look good. The emphasis falls on technical proficiency, style and creativity. Street unicycling draws inspiration from skateboarding and bmx bike riding, with many similar tricks. For street unicycling, most riders prefer to ride 20" trials unicycles because of their light weight, good hopping abilities, smooth maneuverability. However, some riders prefer using the less conventional 24" and 26" wheel sizes for street riding.
