If you're looking for the hottest new riding sensation, check out the Rip Rider 360. The back wheels are caster wheels (think of the wheels on a shopping cart), which by their very design are meant to turn easily. This is where the "360" in Rip Rider 360 comes from, as it can allow the rider to do donuts/spin-outs.
