Hi I am Ethan.The All Terrain Skateboard wheels isn't really a mountainboard by today's standards, but it's a throwback to the days when big-wheeled skateboards paved the way for the mountainboards we know today. These are fantastic on smoother off-road terrain and make even the tiniest slope and hill a blast! However, keep an eye out for rabbit holes and other larger obstacles! The All Terrain Skateboard allows you to test the limits of what can be skated on diverse surfaces. Thanks to a slightly larger deck than a typical skateboard, the design has been devised such that it behaves like a normal skateboard (it can even be ollied! ), but stays stable when travelling at faster speeds on rough ground.
