A quick lift of the handle and the basket comes off
Handlebar without the basket attached
I also attach a mirror to the left side of my handlebar. It attaches with velcro and is adjustable. I really like to be able to see traffic behind me. It easily detaches so I can carry it with me when I lock my bike.
I decided to buy a rear wire basket to attach to my rear rack instead of panniers. It is also a Wald basket.
Rear Bicycle Basket I secured it with plastic ties and this way I can detach it easily if I need to. This basket is really handy. For groceries, I have a cloth bag liner I can carry into the store. It holds a lot of groceries and it rides very nice even when fully loaded.
With this setup I can easily carry food for 3-4 days.
