Does your controller have power control? Don't slam it to 100% for the hill climb. Run it at say 50%, and use your legs. A long continuous hill climb can be tough, and unfortunately your hub motor isn't designed to use gear reduction.
Thanks for your reply
1 - No, they only had this electric bike model and it was end of the line (kind of a clearance sale). When I take the bicycle to the store they just accept it and then send it to the manufacturer for the motor to be replaced.
2 - Yeah, I was thinking that a 500w motor probably wouldn't work with this controller and battery, but assuming the controller is 14A, wouldn't the power output be 36V * 14A = 504w ? Or do I have to include the battery amps in the equation too?
3 - Yes, it has 3 modes (low, medium and high assistance), and I usually climb the hill on high.
