Okay I need advice I have 52 volt bike controller the switch too turn it on and off is full voltage of the battery which is 52 volts I have a motion trigger that you wave your hand over to turn things on and off what type of relay do I use so basically I need a relay that I can trigger too allow 52 volts threw?? Does it make sense

What type relay is need?

 

You need a relay that has the coil rated for the voltage on the output of your motion trigger device, and contacts rated for the maximum current and voltage of whatever is being energized.

 

What type relay is need?

What is this motion trigger and how is it connected to the controller ?

 

In addition to the questions already posed, there is the big question of how many amps will flow in the circuit you are wanting to switch on and off. THAT IS IMPORTANT.
NEXT is a question about the "motion trigger", and how it is intended to connect with whatever it is used to control.

Without you providing the answers to those questions there is no reason to continue the discussion.

The answer is already there in post #3

 

Technically a lower voltage coil could be used with a series resistor.

 

Certainly sg is correct. BUT to suggest an arrangement to control any relay we need to know about the output connection of the "motion trigger" device. In addition, it seems like it would be rather unsafe to use an undefined device to control the drive package of an electric bike.
And still we are left to guess about the amps that any relay would need to switch.

How is your controller turned On/Off currently? Does it come on for example using a key switch? I see at least three 52 volt versions and only one shows a pinout. This is a typical example:


Since I don't see an Enable line I will assume the Battery + and - are energized somehow? Like a key switch or similar? I am not sure what PAS actually is.
