For all those who says it's a penis; never mind if you think so. The deck just show your maleness and radiates humanity. It sounds fucked up, but I think it's true.
Getting to the material part, the deck has the best shape for a deck. Reinforced where most scooters are weak like they say, and that you can see in the design. Stronger in the front and the rear of the deck. Also I love the idea of changing parts. That's the problem with TSI. For example you can't change the headtube if you crack it, and that's a thing Lucky has thought about... amazing
