4. Bombardier Embrio Unicycle Concept
The Embrio concept is yet another controversial product made by Bombardier. First of all, it is a one-wheel bike which already makes us wonder what skills you need to drive it. Even though it does look fancy, the concept is rather ridiculous, but we are more worried about the fact that Bombardier is confident that this will be the most common form of transport. We are not that convinced.
