What is a ripstick?

A ripstick is a type of caster board that is similar to a skateboard, but with only two wheels instead of four. The ripstick is propelled forward by twisting the front and back of the board in opposite directions. It requires a side-to-side motion to move forward, making it a fun and unique way to travel. Ripsticks are popular among children and teens for recreational use and can also be used for tricks and stunts. They are typically made of durable materials such as plastic or metal, and come in various designs and colors.
