Air Cooling(Standard Shaft)
Advantage of Air cooling: Easy to build, no need extra equipment. If you want to build electric motorcycle, which have plenty wind to provide cooling air, air cooling will be perfect choice for you.
Liquid Cooling
Advantage of Liquid Cooling: You'll get a better cooling result. Besides, you can use it close position, like a car, outboard, which has no enough wind coming to cool the motor. But you need to make an extra pump to make it work.
