No, D-Fly is not included. I haven't experienced the "battery falling down" issue. I'm loving the frame... definitely the fastest Giant frame. i also have a Propel advanced, and if the wind blows at all where you live you'll find the tcr to be much more stable. Even though the geometry is almost identical, i can still get more comfortable on my propel though so i need to do a little more tweaking (same saddle/stem/bars). I pretty much stripped mine down and changed everything except for shifters & brakes.
