A Uni-Cycle is a one wheeled bike that is solely man powered. Its main features are pedals, saddle, seatpost, the cranks, fork-style frame and a single wheel.
All the characteristics of a Uni-Cycle are similar to a conventional bicycle, however the one wheel is directly connected to the pedals from the crank, instead of the usual chain on a bicycle.
Uni-Cycling does not suit a specific person for any one specific need, but there are many different variations that have been made to the conventional Uni-Cycle, such as the giraffe Uni-Cycle or geared Uni-Cycle.
There have also been a lot of variations to traditional sports that implement the uni-cycle, such as Uni-cycle Hockey and Basketball.
Uni-cycling is a great form of entertainment and even has competitions, but it is not very conventional for traveling purposes.
