The Wave rides on two caster wheels and carves like a snowboard fusing the motions of surfing and skateboarding all in one! The Wave's two 76 mm urethane wheels (with Abec 5 bearings) spin 360 degrees allowing riders to self propel by going forward, downhill and even uphill by just bending their knees and twisting their hips and shoulders. Can hold riders up to 250lbs. Item Dimensions are 34.5 inch x 8.5 inch x 4.5 inch - Weight 12 lbs.
