Hi, I have a bit of a... weird one here.
I have a BionX G2 motor system with 350W hub installed on the 20" front of a tricycle (don't ask me why, it's how I found it), so naturally it's a throttle based system. The battery pack was toast so I added two DC-DC converters (12V and 5V), terminated the Canbus lines to the battery with a resistor, and powered it off a LiFePo4 pack I already owned. This means the system powers on, motor runs on throttle, and so on - just no regen or battery level indicator.
So on to the problem - when I enter the console codes to see what the max speed and max throttle speed are (which isn't adjustable, oddly), they both show 32kph. However, the motor rolls off power when it it 22kph, even if you have the wheel spinning freely.
Any ideas?
Edit: Is it perhaps hitting an RPM limit? 32kph on a 26" rim is roughly 265ish RPM, which works out to... 23-24kph hmmm. If so, any way around it?
