The color scheme can be black, red and white or black, blue and white.  I like the idea of having a logo separate from the company name like some of the examples provided.  The logo needs to incorporate a camera and bike.  It can be the aperture design and a wheel, the aperture as the front wheel of a bike, or anything you can think of.  Maybe even play with a design that highlights the two Xs in the company name.  The bike needs to be in the style of a mountain bike as well. I added a couple of logo examples of a bike and aperture. 

It was a pleasure to work with Redcrow.  The quality of the design was excellent.
