We see a lot of wonderful technology and information on mobile and the internet. The mobile we use is also a wonderful device in which we see a lot of information. With mobile we can do many things sitting at home which can be called a wonderful technology.
We know that the current people love to ride. We ride in many vehicles. Some ride in a car, some in a bike and many in a bicycle. You also ride a bicycle and laugh. Two or three wheels of the bicycle you ride will laugh. But you have never seen a bicycle with one full tire and two half tires. 
You may be surprised but there are also bicycles. One person has built a bicycle with one whole tire and two half tires with his own hard work. And that cycle runs just like a normal cycle. Which has created an amazing cycle of laughter as you see in the video.
