I've purchased my XM-5000Li Extreme bike December 2009. Needless to say I've been very disappointed with the support from Green Max or API. I have no contact with the company for some time and have given up any hope of help from them. My XM-5000Li has less then 4k miles on it. Since last Summer I've been struggling with the constant problem of the Hub Motor lid becoming unseated due to stripped tread holes. I've had new holes drilled and retreaded with new bolts, but now the motor won't turn it just jumps for a slpit second and shuts off. I am very confidence my wiring reconnections are solid and good. I can only suspect that perhaps the rear axle or the hub motor bar maybe bent and maybe the cause to the motor not running but am not sure. I've double checked my connections and checked for loose wiring which may affect the motor shutting down. No luck.
I would appreciate any help or assistance someone can offer.
Would a new Hub motor require a new controller as well or can I salvage this motor?
Hub Motor spec
5000 watts Brushless Hub motor
