I don't know.
If I swap out controllers then I'd have to swap out the front wheel and add a disc brake. Because without the motor brake that the stock controller has, this thing is very difficult to stop.
A replacement controller is only $65. And they can be upgraded to run at 72 volts by simply replacing the mosfets.
There's someone on the VisforVoltage forum that probably has a spare controller I can get for a lower price.
