definitely a sweet idea, logo shouldn't be too difficult.
Pictures, why not all three, what would be so hard about taking photos of spots and while riding. post pics of the gear your using once or twice then just shoot whatever, fun spots, awesome tricks.
Personally Im a bit more of an action man myself but its all good, I would suggest trying to find a good .asp designer, that will really help the look of your site, and I do go occasionally but instead of categorizing your blog by dates maybe by brand of product reviewed? its difficult to navigate your site when many posts contain multiple reviews of varying equipment for a given date when a specific model review is desired. Just some food for thought
