DDOS - student project

DDOS Bicycles is an actual business idea formed by a friend of mine, involving selling single and fixed gear bicycles.  I want to show grit, mechanics, and yet remain classy.  This will be challenging.  DDOS - image 1 - student project

New Logo Idea that I'm pretty sure I'm gonna keep, drew it in Photoshop and is still very basic.  Is it a keeper?  How can I add vintage bicycle elements into the logo to make sure people know it's for a bicycle company?

Here's my newest design; I'm going for a native american color scheme and theme, attempting to substitute feathers for gear teeth.
