Unicycle trials

[1] The obstacles traversed can be set up specifically for the purpose of unicycle trials, but are often walls, railings, ledges and other "street furniture" found in an urban environment.

Jumping is a similar to hopping, except that the unicycle seat is held in front of the rider to allow greater height to be achieved.

This allows for larger tyres to be fitted which can help provide bounce and preload for jumping, and aid stability being generally quite wide (some up to 2.5 inches).

Unicycle wheels have to withstand large lateral stresses because, unlike in conventional riding, the rider may jump sideways.

Many trials unicycles have a splined hub and cranks, as this design tends to be more resistant to bending and breaking than the more common cotterless, or square taper, equivalent.
