Hi again and thank you for the tips.
I did some and have done some searching here
There should be no problem using a relay, as it will be a NC\NO relay.
So when there is no power to the relay they are Normally Closed, on Power they are Normally Open.
This way it`s absolute impossible to have they shorted the same time the controller is giving the motor power.
The wire to motor cant have both.
Anyway, I tested this today on one motor, and the speed is reducing, but not 100%, it`s more like driving in mud feeling. But it helps.
I did also got my throttle today, but it does not work.
I dont know if my controller is "special" or stupid, but the only way to make it work is to have 2 switches.
One switch make the wheel goes SLOW, swithc and then it goes FAST, use the second switch and it will go even FASTER.
Adding a throttle does nothing..
Here is my controller:

and here is the throttle I have:

I want this car to work with both Brakes, Throttle AND reverse!
I can find many controllers for bike that have throttle and regen\Brake, but not reverse.
Maybe it`s not possible to find both?
I want to buy 4 new controllers to this car (4X hub motors) 4 wheel drive.
But before I buy 4 new one, it would be nice if anyone can reccomend any that they know can fit my needs
Thank you again for all help.
