I’m no skateboarder and never have been, but if I was, I would definitely get the Snap Folding Skateboard. I’d probably break my neck, but still. It makes it super easy to carry your board with you anywhere. The design lets you fold over both ends making it smaller and easy to throw in a backpack.
Assuming the hinged parts lock solidly into place, there’s no reason why it shouldn’t perform just as well as a standard skateboard either, so it is probably just as good as the one you use now. Just fold this baby up and stow it in a bag and you will always have your board with you, ready to go at a moments notice.
If you want to give it a try, you can get one right now for $120(USD), with free shipping in the US from the AtiUSA website. That’s not bad at all for the added convenience.
