We've used a variation of the pyramid logo for years and have simply changed the colors.  We would like to update the event logo.  We don't necessarily want an homage to the old graphic.  We DO NOT want "racing" style bicyclists in the logo -- nobody hunched over, looking fast, or Tour de France style.  We want more normal people enjoying bicycling (if a bicyclist or bike is used in the logo). 
No date on the logo.  We want to use the logo for multiple years.
No acronyms -- we don't like to use them for marketing.
