Unicycles are objects used for the unicycle race in Rescission. They are very unstable and difficult to ride on, as shown in the episode. Leafy had gotten used to it, and Bubble won unintentionally without knowing how to ride a unicycle.
Unicycles are bikes with only one wheel. It does not have supporting parts to hold on, only the seat and the wheel.
- For some reason, this Unicycle does not have pedals.
