As others have said, the wider tires of the mountain bike might have helped a bit, and I'm also wondering if your mountain bike wasn't a little smaller. This would have kept you closer to the ground, lowering your overall center of gravity...
But yes, many people on Citibikes are a menace, so don't necessarily blame yourself.
