I have a Crystalyte RoadRunner Hub Motor (4825R) on 26" front Wheel. I use a 48V 10ah LiFePo4 pack with a 15amp controller. This has been working great for 2.5 years. While riding home from work last evening suddenly something bad happened. Power to the motor was decreased about 95%. The wheel will hardly move at all. There is a lunging/clicking sensation when I throttle the accelerator. I checked all the connections, and everything is fine. I turned off the controller for a while and pedaled. I then tried it again and it worked normally for a couple minutes, then it went right back into lunging/clicking and barely working. I have no idea what happened. Can anyone venture a guess??
Any help will be greatly appreciated.
