Simple answer : it not only looks cool, but it is cool! You see people taking a second look when you pass them or pull up next to them.
Cowboy offers a smooth ride and I arrive quicker at the office without breaking into a sweat.
Only one point of improvement, and the reason I don't give 5 stars: the tires. They are not that good! So come on Cowboy install kick ass tires by default and the sky is no longer the limit :-)
