The small wheels on the front and back are an add-on, called fangs (https://land-surf.com/products/fangs%e2%84%a2-2-1). I’ve had them on my Onewheel for years and I’m not sure they’ve ever actually saved me on a nosedive. The front of the board comes down with a lot of force very quickly and even if the little wheels do keep the board rolling, the rider has been rapidly shoved forward and will likely go over the front anyway.
