The Balanza Freeride is an ideal tool for anyone who skateboards, longboards or participates in any other board sport. This training board can easily be used inside to help you practice and train your balance. The inflatable balls provide feedback you can see and feel to help you fine tune your footing and weight distribution. This also helps when teaching others how to balance on their boards because you can easily see what is happening. In addition, the inflatable balls can be adjusted for a custom fit that best represents your real board. To adjust the pressure, simply use a needle ball pump. 440lb/200kgs weight capacity.
