XDS 007C Speed governor removal

[Rickard Sweden]

Hi, I have a 36V/250W XDS 007C ebike which I am very satisfied with. Ok, some components are cheap but overall it fulfilled my expectations for that bike and the price. However, as almost everyone else I want it to go a bit faster. It is regulated to 25 km/h according to swedish law so above that speed the motor will not assist.

I disassembled the controller and found a suspect jumper. Anyone with experience that could give me courage to cut that wire below the arrow?

That "jumper" is called the shunt resistor. it's on the main power supply from the battery to the motor, so cutting it would disable the bike, and since it's made of cadmium wire and calibrated to a specific resistance, repairing it once cut would not be easy.

If you have a jumper for governing the speed, it will commonly be a single wire that exits the controller, goes to a single wire connector, and then re-enters the controller. Usually they are white, but I've seen them in blue.

Otherwise, the governor is probably done through software.

Thanks. I have never seen one of them before and that was the only option on the board so my mind was lead in the wrong direction. So, the speed governor is then hidden in not accessible software. Maybe accessible with a secret combination of button input on the "display" (just power on/off and 1,2,3 assist mode and one button for GPS). That might be cheaper in stead of having separate software (configurations) for different regions.

Leaves me with trying to fool the speed sensor, if there is one that is. Can speed be monitored by the motor itself?
