What have you list folks come up with for small load carrying if you don't have rack, basket, bag or panniers on a particular bike your riding at the time?
Perhaps you gave carrying capacity on all your bikes?
Example:
one or two grocery sacks worth.
If I'm on a bike without rack, basket, etc.
I've been using the heavier duty cloth grocery bags available at the likes if Trader Joe's, Whole Food or Natural Grocers.
I find there're easy to double tie and remove from handlebars.
One needs to be careful as to impact on steering.
Balancing out two works fine for me.
Of course I only do this for short trips of 2 to 4 miles or so.
