Deepa, I wonder what added benefits this design has over the regular roller skates or skateboards? Using skates or boards is quite popular while people will need to get used to balancing on this completely different design. It sure will have fancy value but may be hard to reach popularity of normal skates.

The only added benefit that I see is that they are compact and can be shoved in your work bag. Just two wheels, thats it.

Now I guess compact cars are already a thing in the pass. It’s a great idea for Daniel Julier to come up with this kind of transportation realizing that we are too dependent on fuels, batteries, electric motors when it comes to ultra-compact cars and segway-like vehicles. This concept is a one of many alternative energy sources.
