EZ Raider thoughts?

Hey Have you guys seen these things. They look kinda like an over grown skate board. They are calling them atvs but ye, i have wanted to build something similar to this but have have never had a whole lot of confidence that the hub motors would preform quite well enough. Would love to hear your input. I know there was a build a while back that was like this but chain driven and more of the skate board feel.

Not sure if i am allowed to link to outside website but just google EZ Raider and they come right up.
