I weigh my bikes as I ride them less WBs and panniers.

Ticycles geared: no fenders on - ~24.5#
TiCycles fix gear: no fenders on - ~20#
Peter Mooney: with fenders, Lowrider and rear racks - ~26.5#
City/rain/winter fix gear: with fenders, Lowrider and U-lock - 28.5#
Raleigh Competition: no fenders or rack - 27# (Fairly wild guess. Frame is 531 and light but nothing has been weighed as it has gone through changes. Seatpost is the very heavy SR adjustable setback post.

I don't work very hard at saving weight. I place function over weight almost every time. Now, light spokes, lightish rims and light tires make bikes really fun to ride. Almost no drawbacks to light spokes (if you are light, kind to wheels and build good ones). Ti railed seats offer a superior ride on rough roads but I offset much of that weight savings using large seatback posts to center the rails and improve rail life. On my lightest bike, I have significant weight in fenderwashers on the toestrap bolts to hand the pedal correctly for good pick-up at starts. (A first try pick-up is a huge leg saver on steep hill starts on the fix gear.)

All my bikes include a toolbag with two innertubes, patch kit, appropriate hex wrenches, usually a small tube of sunscreen and perhaps another tool or two. 2 WB cages. A full frame pump (Zephal HP or HPX size 3 or 4).
