The biggest issue I have with getting more than 20 miles out of my e-bike is the controller. The manufacturer of the controller set it to shut off when the battery pack hits 42v. (using a 52v pack) Sucks pushing a bike up a hill when you know you still have ~15% capacity remaining.

That's to increase the life-span of the pack. At 15% max discharge the pack will live much longer (orders of magnitude) than if you were to ride it down to zero. This is precisely why I over dimensioned my pack.
