I am planning on a electric bike build this winter. I have a K91-4003 Motor and it is not liquid cooled. I was curious if this is going to be an issue or if there is a cooling jack or heat sink that would fit around the motor to better dispurce the heat. Any ideas or? Was curious if I could do a radiator set up having a small water pump run the coolant through the jacket to keep things nice and cool. Any thoughts would be appreciated.
