Black Bikes

Today i spent some more time on the mountain bike for just a bit of commuting. Spent roughly 40 minutes out on the bike today. Riding around town on it is ok but it does have some drive train issues i need to work out. It does its job though. I also took the old steel bike out and have plans to fix her up. I want to turn her into a black ninja bike, haha. I just need to practice my Ninja Skills.

I'm looking for ideas for my bike so here are some examples of black bikes.
