I keep a change of clothes at work (and my employer provides lunch) so the only thing I carry on the bike is a small handlebar bag with my personal items (wallet, mobile phone, etc). I hang the bag on my rear rack though because there's no space on my bars (with the bell, lights and cross top levers it's a bit crowded). I'd have ditched my rear rack long ago otherwise lol (no like riding with backpack).

This is my bike on usual commuter mode.
