BMS Q128C Motor was practically new when clutch hung up.
I complained to seller to no avail.
My wife has been riding around for past 100 miles knowing that the hub motor clutch was stuck.
I did not want to tear down....no time or desire.
Anyway, I had an idea: What if I disconnected motor, shorted out a winding, and give the motor a quick spin in forward direction?
Sure enough, immediately upon spinning wheel, drag caused by shorted winding gave enough resistance to free clutch!
I heard/felt a slight pop and wheel spun freely going forward direction.
Fixed!
I'll keep an eye on it...expect it will happen again until things get broken in.
PS: Be VERY careful when shorting out winding...you do not want to feed voltage (created by turning wheel) back into any of the hall sensors!
