Look at the picture on the right. This strange gadget is nothing but a new brand of a skateboard with the engine. Thanks to it such skateboard reaches a speed of 31 km/h (16-19mph). Speed can be regulated with the help of a pneumatic ball in your hand. The stronger you compress it, the faster you drive. To pull up all you have to do is just to stop squeezing and as a result the skateboard will come to a halt quite rapidly but softy at the same time.
You can run this wonder of engineering the same way as a common skateboard - by body moving or bending. Besides, you're able to rotate a front wheel with your foot from side to side. Extreme lovers should be ready to pay $1500 for a Wheelman (the name for this invention). As for me I would do it with pleasure.
