For the birthday of my lovely girlfriend I decided to make her a cycling bag. She commutes to and from work by bike and needs to carry clothing, food, tools and sundries, and has been resorting to strapping a purse to the rear rack with bungee cords. I thought that a design with the least amount of removable parts would be ideal, but it would need to be easily installed and removed. I also wanted it to double as a purse while off the bike, and she's a sucker for giraffes, so the following bag was born:
The strap is removable, and can be carried in the bag while it is strapped into place.
Continuing the giraffe theme, there are giraffe heads at both ends of the bag for the purpose of mounting a rear blinking light:
The underside serves two functions - to hold the bungee cords and also to carry the u-lock. When in place on the rack, the hooks can be snaked under the rack and hooked onto the d-rings, providing a simple and secure method of holding the bag to the rack. As they're attached to the bag there isn't any chance of losing them:
The u-lock in place. It slides into a slot on the underside of the bag and eliminates the need to carry it elsewhere:

This better illustrates how the bag attaches to the rack. It doesn't matter how much gear is stowed in the bag, as the low attachment points will keep it firmly in place no matter what:
A better shot of the u-lock in place. The bungee wraps around it and keeps it from sliding out:
