I'd planned to use just the one pannier most of the time so I hope I manage to balance okay. I do have a single grocery pannier that I thought I'd use on the other side when I have more to carry.

I use my bike to run errands on the way home from work and at the weekend so I wanted a bag I could take on and off and carry easily that would look more like a normal bag. I'll see how I get on with the attachment - if it's too much of a hassle it won't be so useful to me.

I'll post a review when it arrives next week.
