Hello,
I hope someone here can help me. I purchased a used Stromer ST2 that has less than 120 miles on it. It has the latest update on firmware. The bike is a 2016. It is no longer under warranty. Took it out for a ride and as soon as the power is applied to the Omni display, i encountered a drive error 0X210002. Tried to reset by taking out battery, wait 10 min and put battery back in same issue. Took the controller out to visually inspect, i don't see anything obvious. I suspect the hub motor (Syno drive) may be the problem. I removed the wheel and torqued to 20N-m. Still same issue. There are two connections. One for the power to the hub motor. The other is a small quick connect for low level hall sensors. Does anyone have a pin out of this connector. I am trying to see if the hall sensors are working and also make sure there is no broken wires, pins.
If anyone have seen this fault and remedy please let me know. It is an expensive bike and I am trying to make it work. I saw at the Stromer NL site, the controller may need to be replaced. problem is I do not know if this would solve it and that the controller is about 300 dollars on ebay with no guarantee. Is there a way to eliminate the controller being the culprit.?
Worse case, if the hub motor is good (not sure how to check the bldc, phase to phase resistance is consistently low i.e. 0.4 ohms), can I just purchase a generic 48VDC, 1000W controller and make it work.? It is a nice and light frame, it would be good to solve this problem. I appreciate any help any one can provide.
This would be the first time I rode this bike since purchased.
Thanks.
