Mauricio:
Sounds like there may be a connectivity or voltage issue between the battery and motor.
We recommend a diagnostic test, testing the battery for voltage and testing for voltage to the motor,
making sure the battery is good, we have good solid voltage numbers to the motor.
A diagnostic test may reveal any other issues.
Let us know what is found.
Thank you and best regards,
Leif Fleming.
I took the battery off and checked the voltage, the voltage was good, then I took the controller off to check for voltage to the motor and opened up the controller to look for the hot wires and I found a short circuit in the controller box, the yellow phase cable and all around it has significant burn marks including the green phase cable insulation.
The controller box is the:
AA508011626
CN32QT
R3 48V
17C01249
Mr Fleming immediately ordered and got a discount for me, the part it was $199.00 after the discount = $135.00 with taxes and shipping and handling with FedEx, 3 days later the part got delivered, installed the controller and everything back together, took it for a spin and is working like the first day (smooth quiet and fast).
Thanks to Mr Fleming, Haibike Technical Support and Alta Cycling Group LLC.
I hope this information could be helpful for someone having the same problems with their Urban Plus Bike.
