Boarder Kontrol makes descending hills on a skateboard fun for beginners. As you can see, with the brake pulled you can step onto the skateboard safely without it rolling out from underneath you. Gently releasing pressure on the leash disengages the brake. As you descend the the hill, you control your speed with the leash. As your confidence builds you can progress to other things like carving and eventually riding the board on the flat without the leash.
