Electric Bike Review is best if you see this. You are a fool if you think you can ride fast all the time. Once you have to go slow because of the terrain, your hub is not efficient at all. Might as well let it cool down and get ready for the next straights where you can let it hum. About 1000 watts was used climbing this relatively steep but very rocky terrain. It is equal to what you can do with a few to several kw in a hub motor.
