No balance problem. You just automatically lean an extra inch to the other side. You can't even notice it.
That is, unless your bag is on the left, as mine is, and you have an 8 pack of soda in it, and it overbalances the kickstand and crashes. You can avoid that if you think to allow for it and turn the wheel away from the weight.
