I don’t think you really remember this concept and even if you do, you didn’t read my opinion about it. At the beginning I would like to say that I love so much this concept just by the moment when I saw the first photo with it.
Anyway, the bad thing at this concept bike is that it is very dangerous as you can see on the photo on how may stay a man on this bike. A good thing is that it is electric and it can also reach high speeds but the thing that is different on other bikes, on this bike can ride only one person.
There is no doubt that this is a futuristic bike and I think I saw some bikes like this one in Sci-Fi movies. There are some chances that in the future, the streets to be full of this kind of bikes.
