Thanks for the feedback guys! Sounds like the Sirrus Sport will be the way to go. I was considering going up to the Sirrus Elite but that's a $200 difference and I probably wouldn't even figure out what the difference is riding it. (Might as well spend the extra money on accessories)
Anybody else about drop bars vs flat bars? I remember when I was in high school I had a flat bar bike and I would take it on 10 mile rides on a nearby bike path though that was a once in a while deal vs daily.
As for lights, I'd be biking around 7-8 and 5-6 so in the summer it might not be a big deal. I have a safety vest at work that I could wear to be more visible.
I don't really bring anything to/from work other than my lunch so I highly doubt I'd be carrying anything heavy.
Thanks for all the advice so far!
