I haven't weighed my primary commuter yet, but I'd guess its basic weight with racks, fenders, lights, etc (and none of my gear) would be in the 30 lb vicinity. I ride with 2 panniers in back, loaded with my day's clothes, shoes, spare tube, patch kit, pump, multi-tool, 15mm axle wrench, backpacker's first aid kit, wallet, keys, toiletries, etc. I'd guess both panniers check in at 15-20 pounds or so total, so my loaded commuter is about 45-50 pounds.

I can say that the bike does not feel that heavy when I ride.

My other commuter is probably 25 pounds as is, and I pack a single pannier for the front rack with less stuff, say 10-15 pounds max, so the loaded bike is 35-40 pounds.
