RipStik

The RipStik is a caster board, a type of recreational sports equipment. It consists of two decks connected by a torsion bar, which allows for twisting and pivoting. Each deck has a polyurethane wheel that can rotate 360 degrees. The design is intended to mimic the motion of surfing or snowboarding on pavement.

Riding a RipStik involves a unique side-to-side motion of the hips and legs to propel oneself forward. Unlike a traditional skateboard with four wheels, the RipStik's two inline wheels and twisting deck create a different kind of momentum. This requires a different technique for balancing and steering.

RipStiks are typically made of plastic and are available in various colors and designs. They are often marketed towards younger riders but are used by people of all ages. Safety gear such as helmets and pads are recommended when using a RipStik due to the potential for falls. The RipStik is manufactured by Wavemaster Technologies.
