The cables have to be pushed behind the bag, but I am going to experiment with a fastening system to hold them closer to the front stem, yet still allow for the handlebar folding.
Handling is different, best described as more solid and not as nimble. I do not see that as a negative. It does not seem practical to leave the bag on while folded, at least not when loaded, but the quick release works great and I just keep the bag with me on the train (including snacks and coffee).
Hope that helps.
