Hey everyone! I'm new to this forum and I was hoping I could get some help.
I have a BionX D500 DV motor system installed on my road bike.

I rode it outside yesterday: first in an empty parking lot, then around town. It seemed to be functioning perfectly: throttle, pedal assist, and regenerative braking all worked.
Today I was using it on my turbo trainer to test its throttle and braking response in a controlled setting. During part of my test, I set the braking mode to 4 (the highest setting) and sprinted as hard as I could. The resistance was very high at first, then started to ease around 20 kph towards a minimum around 40 kph. After this, the resistance increased again up to about 55 kph. It eased again until at about 70 kph, the motor suddenly turned to drive mode and accelerated to 87 kph. At this time, I stopped pedaling and the motor quickly slowed the wheel down. After this, the head unit began beeping in rapid pairs repeated every 1 second. The assist mode bar on the control unit blinks in sync.
I start pedaling again while the system is beeping and the resistance is initially very high: twice what it was originally. Concerned, I dismount to examine the system.
Now I troubleshoot. I turn it off and on again, hoping the issue would go away.
The beeping resumes. I try pedaling again. I change the throttle setting through its full range and it has no effect. I push the throttle button and it has no effect. Despite pedaling again significant resistance for a substantial period, the battery charge is no longer increasing as it was. When I get to about 20 kph it decreases until the resistance is almost gone at 40 kph and does not increase again despite pedaling up to 96 kph. I shut off the system and disconnect the motor signal and battery connectors and find that the resistance is unchanged. The motor must be passively dissipating my work internally. When pedaling with the system on, the system seems to recognize that it's in generate mode and displays red, indicating that I'm charging it. At high speed it indicates a lower charge rate or even flashes slightly to green (drive) Through all this, the control unit and display seem to function without issue. I also restart the system a few more times allowing off time to no avail.
This is quite disturbing to me as I've only been using this bike for one day and now it seems inoperable.
I would greatly appreciate any expertise in trying to reset the motor to normal operating mode.
Thanks in advance,
~Bill
