If you have close-ratio gears, you don't have as much room to gear up...if you have wide-ratio gears, you don't have as much room to gear down...if you have standard-ratio gears, you have much more room to gear up or gear down, and aren't limited by an already high or low ratio.

I gear for 40mph, but as long as you have the right battery(s), you can gear for whatever speed you want. For me, 40mph is perfect for the area I run in. If you want to gear higher than 40mph, you will need 150A or higher batteries.
