Ron, you are still mistaken, while it does take less energy to increase speed over a standing start you have lost mechanical advantage and thus have less power at any point while under power driven from that gear at the rear wheel. You do not magically regain that disadvantage just because you are already moving.
As for the lever if you have the power to lift all the way then yes you can lift higher but it takes more energy through the entire range to do so. This equates to the extra energy required to turn the rear wheel through the entire range.
I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
