Order 20 inch 48V 2000W front fat hub motor electric bike conversion kit
Q: I need to order this item Item ID #LBCK20482000FS 20 inch 48V 2000W front fat hub motor electric bike conversion kit and all have to do is install it and it should be ready to go using my 60V 20A lithium battery ? Is it very difficult set up? Will there be instructions on how to set up the LB08HU? Is there an app to connect to the LCD display? Approx time if I order to get it shipped?

Will this this kind of hub motor melt if a heavy biker rides it on a 20% grade steep hills and electric hub motors are a challenge and require a properly sized and adjusted system to avoid overheating. The torque a hub motor can make is related to the physical magnet strength, width, air gap and diameter. The winding arrangement determines the voltage and current to make this torque. I also would like to add a part for better cooling.

Did you get my update info,Please advise if the one you recommend will meet these requirements.
