Don't show up unprepared.
Riding to work is a joy, but it's even better if you don't have to sling your gear over your back on the way there; instead, slip it all into Timbuk2's Sunset Frame Bag, a sleek, briefcase-style bag that works as well off the bike as it does on.
Belt buckle attachment straps lash the Sunset securely onto virtually any frame, and the carry handle makes it easy to take it into a meeting when you have to leave your riding pleasures at the door. Timbuk2 integrates a zippered pocket into the top of the Sunset, making it easy to stash your keys, phone, and wallet for quick access. Internal organizers provide a more permanent space for electronics, pens, and maybe a snack or three.
