I have the need to stop my tricycle front wheels from the left handlebar lever (right, rear) but can't find a handle brake that has double cable in the same handle to disconect the motor.
I bought the GM handles:

but I need:

+ the cable to stop the motor. all in one, like the GM handle brake but double.
I explain well?

someone can tell me where I can find, double and compact, not expensive and can be sent to Spain?
thanks!!
